Are you sure about the first picture? It seems to me like some bigger bizjet - a very bad configuration for nuclear powered plane...

I`m not sure Matej ???

In that magazine both pics are shown in the news section and the only text below it is "Lockheed Nuclear Projects". Any help to identify it will be welcome

The illustrations shown us by Pometabla' appeared also in
'Au dela du Ciel' of January 1960.
Illustrating two nuclear powered design conceived by Lockheed.
One civilian ,with the foreplanes, and one for military purposes.

The military aircraft  was one of the preliminary
studies in 1949 for a nuclear powered bomber by Lockheed-California
under their TDD designations CL-225-263-284-286-293-313
and 319.
The research was then transferred to Lockheed-Georgia where
work was done to meet the requirements of the USAF Weapon
System 125 under a variety of TDD designations
beginning with GL-145.

Several sources but mainly:Lockheed Aircraft since 1913.
                                     René Francillon - Putnam. 1987.

Nuclear powered aircrafts are a little studied topic. In particular, we lack a comprehensive review of all the actvities done by aircraft and engine manufacturers. Lockeed and Convair are well known for having being interested, but other manufacturers were involved as well. Fairchild (the orginal one, not Republic) was in the early NEPA study,, and even Hughes had some projects (probably based on the H-4 ?) And then naturally there is the late (1959) Martin studies for a nuclear powered seaplane (seaplanes, preferibly big ones, one of my passions, d'ya notice  ;D ) Boeing did extensive studies, too.

Speaking about Martin...

There's an illustration of the Martin 331 nuclear powered
derivative of the Seamaster on the site of AAHS journal...

Two other examples for aircraft with nuclear propulsion:

1. A 1950s helicopter by Bell (the same problems to protect the passengers against the radiation in this two-deck configuration). (Source: „Hubschrauber und Vertikalstartflugzeuge“ by Just)

2. A Lockheed heavy-lift transport with a range reaching ‘round the earth’, shown in the “Flug Revue” 9/1978.

Has anybody an idea of the model numbers?

O.K devi,

I send the ' L' list to my Friend Pometabla' and he will put it on the
'designation' file.

For the reccord. Only the complete L list is in the book.No CL nor Gl numbers.

Indeed .

The list contains only Lockheed basic model numbers
starting with model 1 on to model 99 , a USAF  interceptor fighter
project who was cancelled in 1951.

Just found, when I was searching something totally different :
Proposals for nuclear powered cargo seaplanes, either with turboprops,
or turbofans, made by J.F.Brady, engineer at Convair Division of General
Dynamics Corporation.
(from :AviationWeek, 4/1960

From the opposite side of the "iron wall" - some not very often seen installations of nuclear reactors on Myasischev M-30 and Tupolev Tu-114.

It was published in article The atomic aircraft: Future in the passed time by A. Y. Sovenko in Aviation and time magazine, 3 and 4/2004.

Here is part of the info on Martin Nuclear seaplane projects from the Fall 2006 AAHS Journal.
The Martin 331-1 which was basically a modified P6M.





As the project proceeded the design diverged more and more from the P6M baseline.

This is Model 331-6, from first half of 1956. It was leghtned to house the new version of the GE AC-110 reactor with turbojet integrated in the reactor frame. From Stan Piet's "P6M".

the Lockheed also designed a nuclear powered aircraft,the L-125,
L-195 and L-212,I don't rtemember the site which mentioned
that info now,I will search about it,but has anyone a more info
about them ?.

I've often wondered how these nuclear aircraft were meant to work (or rather their engines).  How does a nuclear jet engine work?   Surely it would spew radiation all over the countryside?

Simplest version: nuclear ramjet. In short, air is fed into a reactor, a reactor which is real close to meltdown. The air serves as coolant for the reactor, in the process getting very hot. The heated air is expelled directly, producing thrust. In essense, the heat from the reactor replaces the heat from normal ramjet combustion.

Turbojet version, simple: similar as above, but instead of providing direct thrust, the heated air is blown past a turbine, with the reactor takign the place of regular burner cans in a  turbojet. The turbine then provides mechanical power to run a conpressor and/or an extenal propellor (nuclear turboprop).

Turbojet version, complex: A heat exchanger is placed between the air and the reactor. The reactor is now cooled with some fluid - compressed helium, lithium, various salts, etc. - and the now-heated fluid in turn heats the air. The fluid and the air do not come into direct contact; fluid is contained within metal tubes (like the coolant in a regular car engine, just vastly hotter).

Quote
Surely it would spew radiation all over the countryside?

In direct cycle engines, like the first two described above, yes. In indirect cycle engines, no. The reactor is still hot and emits gamma rays and neutrons, but does not emit radioactive exhaust.

There have been nuclear UAV studies quite recently. It's not as crazy as you think. First, there's no crew to be protected from long-term exposure a few feet from the reactor. Second, you can use jet fuel to climb to altitude before turning up the teakettle, so you need less shielding around the engine. Third, you can actually exploit the nuc's advantage:  unlimited endurance.

Since such high glide ratio UAV:s could get by with relatively little power, I wonder if a nuclear battery could work instead of a reactor. There are already solar UAV:s in the works.
Some nuclear materials glow even red hot by themselves. You could probably build it to survive a crash without spreading the radioactive material around. A jet, fan or a stirling engine prop might be the best way to extract power.

I don't think the nuclear aircraft idea would have been successful

Nuclear cores seems don't transfer very well the heat to the medium, because the heat is absorved by the fuel/moderator mass, 1000-1500ºC would have been the best transfered temperature, not very good for a jet propulsion concept

Maybe for some kind of turboprop with steam cycle (or some kind of gas using  stirling cycle) would have worked

That's right and it will protests from many people ... if they know ! If not, then not ...
And remember, several satellites were using radioactive material, too, an sooner or later,
they all come back.
LowObservbles point is correct, I think : A nuclear powered UAV could cruise for very long
periods over an area and, if small and stealthy enough, nobody will notice. And even better :
If it comes down, there's no crew for interrogation. So, if this type it wasn't made public,
It would be quite deniable ! Who ? Me ??     ;D

It's a pity that the hafnium isomer nuclear battery concept turned out to be bunk. It's a neat neat... zap a hafnium isomer with Xrays and the isomer will release up to 60 times the energy; shut the Xrays off and the reaction stops, and you're left with a *non*radioactive chunk of metal. Tur the Xrays back on and it starts up again. A wonderful concept. That nobody was able to replicate. Sigh... more "cold fusion."

You'd have to be insane to do so. Power output of RTG is measured comfortably in *watts.* Not kilowatts, not megawatts.... just watts. Cassini's RTG, for example, has an electrical power output of 300 watts/thermal output of 4400 watts, and weighs more than 50 kg. The engine of a light aircraft can be assumed to have a power output measured in hundreds of kilowatts, and would weight roughly the same as the RTG.

RTG's make great long-lived batteries... but their power to weight ratio sucks.

Would be interesting if somebody shows a RAD table to compare the radiation between Pu-288 and Sr-90 or Cb-60, i think cobalt or strontium have better values than Pu (used on cassini), but then..im not nuclear engineer :P

The cassini generator use some kind of direct transformation from heat to electricity, not sure how could perform with a conventional mechanical cycle (stirling, since it seems the temperature is not high enough to use water/steam)

If they worked. But last I heard, they don't. One laboratory claiemd to get more energy out than was put in; nobody was able to replicate that.

*IF* the system worked, then it'd be useful for all kinds of things, down to and including "atomic" cars. It'd be easily shielded, would not activate surrounding materials, has a good power to weight ratio, and once shut off stops radiating entirely. The tiny little problem seems to be that it just doesn't work.

supposedly there was a soviet nuclear powered aircraft, based on a Bear bomber ..

there are lots of conflicting stories if that aircraft ever flew - some even state that it flew under nuclear power, but the crew dies later due to radiation injuries ..

is there any definite information source on this?

yes .. but did it ever fly - on nuclear power ..?

i can find everything from: it never flew to it flew with conventinal engines (like the US counterpart) to it flew on nuclear power ..

Tu-95 LAL - from May to August 1961 was met with 34 flights operating reactors.
Tu-119 - still at the stage of the project. In the late 60's all work on this topic have been halted due to the changing concept.

just with operating reactor .. no propulsion (like the US counterpart, where the reactor was operated, but never delivered any thrust to the aircraft)

or

actually nuclear powered propulsion ..

Hi! I find this drawing from Japanese AIREVIEW magazine in June 1970.
This was a Lockheed designed nuclear transport. Passengers were 600 and the speed was transonic.
Does anyone know the detail of this transport?

"Would the hafnium-isomer powerpant proposed by the Popular Mechanics article be practical under real world considerations?"


There were a lot of scientists who poh-poohed the isomer triggering idea as a sourve of nuclear energy, DARPA canceled their program and it seemed to disappear.
However, the latest is that, against all expectation, DARPA's make-or-break test showed that it works http://blog.wired.com/defense/2008/08/isomer-bombs-re.html

However, there's a big catch: the isomer they used, Hafnium 178m2, is extremely expensive, and it's unlikely to be used for anything other than very small niche applications such as untended sensors.

That's not exactly true...a number of the white world tests did come out positive - check out Collins site - but there was a lot of politics involved.

Isomer research continues at the DTRA, the US Navy (who still think it can be used for warheads) and the Army (who are only planning to use it for atomic batteries). And, allegedly, at Other Places.

This drawing is just shown here, to prevent anybody else to take it as
a real project, if designated so elsewhere. It really looks good and the
idea, to build the whole cockpit section as a detachable boat seems to
be quite a good one, but ... the whole thing is just the idea of the crew
of the french "L'Air" magazine, where I find it in an 1960 issue.  ;)
It takes a long time, before all mistakes are made ...

I have found an interesting project on the web and I really would like to know from which company the design originated. Here is the accompanying text:

"One idea for an operational nuclear-powered aircraft involved detachable reactor modules that could be replaced as needed. In this artist's conception, the pilots were in the section forming part of the tail, which could be detached in cases of emergency."

I wonder what the letters "US-AS" mean on the top right wing and the top of the reactor pod? At first glance, I thought that the original artwork was damaged and it was meant to say "USAF" when I first saw the art on Retrofuture. Thoughts on what this might be? A fanciful United States Atomic Service perhaps? Yet another example of 1950s exuberance for the wonderful world of tomorrow based on the mighty atom?

It is not necessary that it should be a company. Probably some sort of generic study, done by USAF or another governmental owned institution. I saw this concept for the first time in JC Carbonel web. For the link, see the reply no.20 in this topic.

It's quite an original design, but the article doesn't say if it's Ohlinger's work as an aside or if it's a Northrop endorsed project... Anyway, from the link you provided I was able to capture three enlarged images of the selfsame project. Thanks again!

Model of Lockheed-Georgia nuclear-powered tug aircraft concept towing two Lockheed C-5 Galaxy military transports circa 1980.

Quote
The nuclear-tug design shown here has a gross weight of 2 million pounds; 40 percent would be the reactor. The plane would be a seaplane, and would fly only over water. If it were to fly over land, the design would have to include protection for the reactor in the event of a crash, entailing a heavy weight penalty. The nuclear-powered plane assumes advanced nuclear technology.

Without a payload, the nuclear reactor could supply enough power for takeoff and landing.

there was a study circa late 1950's by the Royal Aircraft Establishment for a nuclear powered tactical bomber loosly related to GOR.339, unfortunately the appendices which would have given a basic ga. drawing had been removed form the copy of the paper at the National Archives at Kew, possibly another issue of the same paper exists at another location? Boscombe Down library?

Hesh,

Awesome find as always. But I have to ask: was such miniaturization of reactors for flight even possible back then? I'd imagine that with all the effort of Convair's X-6 program, doing reactors for aircraft would be a major pain in the a** back then. A C-130 is a bit smaller than a tricked-out B-36.

Not just that... The first screen says "N. P. Princess Flying Boat" which means "Nuclear Powered", of course. This project was undertaken by Convair from May 1958 to February 1959, under the designation ANP, and the many documents concerning that project which are listed in the Spangenberg Index are apparently still classified (Boxes 670 to 676). What a remarkable aircraft design, anyway. Such a beauty, even in model form!

From Modelarchive;

http://modelarchives.free.fr/archives_P/Aplane/Aplane_tech.html

The "Ragnarok Orbital Interceptor" was a 1975 re-issue of the "Impetus" nuclear airliner model kit from 1960 by Aurora. The "Impetus" was a fictional nuclear airliner design based on an early projected version of the Convair B-58. Therefore, it should be considered a fictional concept and a fantasy project.

Thought about it, too, but the description clearly speaks of "Verkehrsflugzeug" (airliner)
and the drawing stems from an article with the title "Wege zum Überschallverkehr"
(Ways to supersonic travel). Maybe the passeneger cabin would have been behind the
reactor  or even in the tail ? It's described as a very large aircraft.

...ISTR a thread on this one on ssh a while back. The landing gear were supposed to be a bit off-centered compared to a normal bomber, and not a tricycle arrangement by any means. I'd say do a googlegroups search, but I'm finding that a *LOT* of posts from the early part of this last decade aren't showing up, probably due to google's preservation of usenet falling way low on the priorities list. Scott Lowther, IIRC, did some research on this one for the Fantastic Plastic kit, and he might be the one to go to on this.

The e-book (I don't know if there was ever a paper edition) "Proving the principal, the history of the Idaho National Engineering Lab" has a chapter on the nuclear aircraft program called "The triumph of political gravity over nuclear flight".  It's a fascinating read and has a lot of pictures from the program.

While not dealing with the aircraft itself, I've read that the US planned to build two rather substantial airfields for flight testing of the X-6, one would have been at what was then the National Reactor Test Station in Idaho (15,000 ft runway, the hangar was built before the project ended).


(http://www.idahoptv.org/buildingbig/buildings/ineel.html)

The other was at Edwards AFB and according to the website linked to below would have run between the Muroc dry lake and Rosamond dry lake.

(http://members.tripod.com/airfields_freeman/ID/Airfields_ID_N.htm)

Similar information can also be found at:

(http://www.456fis.org/AN_AIRFIELD_WITHOUT_A_RUNWAY.htm)

Does anyone know if plans/artists impressions exist for either airfield?

I do not read Russian, but what makes you conclude these are 'nuclear powered'? The second pic shows propeller driven aircraft and designs which are somehow at odds with the nuclear concept whereas the third pic looks more like rockets to me.
So could you please provide a translation of the text so that we can at least know what we are looking at.
Having said that, and pending the translation, these pics look to me like science fiction - somewhat too far removed from realistic projects.

The link hesham posted says in the header "Nuclear Planes Of The Future" and that there are propeller driven
aircraft, not necessairly means, that the power doesn't come from a nuclear reactor, just remeber the planned
conversion of one of the Saro Princess flying boats into a nuclear powered test aircraft.
Nevertheless, looking at those drawings, I think, they are better suited to the "Theoretical and Speculative"
section, as they seem to show "imaginations of the future", not really projects.

We've posted some preliminary design drawings on the Code One Magazine Facebook page as "name the plane" contests. These images, and some other content, don't appear on our website (yet at least). The most recent one is a line drawing for the nuclear-powered Lockheed L-225 (hence the post here).

Please excuse this shameless attempt to score fans for our FB page. With that said, these drawings don't appear anywhere else and should be of some interest to the Post WWII designs forum.

Search for "Code One Magazine" on Facebook to find it.

We plan to eventually post more of these to the website as well in a special gallery devoted to recently released drawings that were rescued from the shredder. It should launch before year end.

Enjoy!

NP-2 and NP-3 look like Lockheed L-225 iterations. In fact I posted NP-2 picture long time ago in the forum from a 50's magazine and it was refered as a Lockheed nuclear powered aircraft.

You can find 1 and 2 in Soviet misidentifications topic here in the forum. They are "nuclear powered Soviet bombers" published in Western magazines in the 50's.

It's probably a long shot, but does anyone have any drawings or illustrations of Oak Ridge Laboratory's early 1950s 'tug-tow' NPB/crew glider proposal?

Emphasis mine.
Quote
There are no fundamental technical reasons why subsonic nuclear aircraft cannot be made to fly successfully providing the aircraft is large enough. The weight of a completely shielded nuclear aircraft reactor varies about as the square root of the reactor power. Hence, the larger the aircraft the less is the weight fraction of the nuclear power system. Aircraft of 0.45 million kilograms (1 million lb) or greater are required to make the payload fraction greater than 15 percent of the gross weight. With funds drawn largely from the U.S. Air Force, the Oak Ridge Laboratory's major entrance into reactor development during the 1950s came through efforts to design a nuclear airplane. British and German development of jet engines at the end of World War II had given quick, defensive fighters an advantage over slower long-range offensive bombers. To address the imbalance, General Curtis LeMay and Colonel Donald Keirn, both of the Air Force, urged development of nuclear-powered bombers. In 1946, they persuaded General Groves to approve Air Force use of the vacated S-50 plant near the K-25 Plant in Oak Ridge to investigate whether nuclear energy could propel aircraft.

The initial concept called for a nuclear- propelled bomber that could fly at least 12,000 miles at 450 miles per hour without refueling. Such range and speed would enable nuclear weapons to be delivered via airborne bombers anywhere in the world. The aircraft, however, would require a compact reactor small enough to fit inside a bomber and powerful enough to lift the airplane into the air, complete with lightweight shielding to protect the crew from radiation.

Under Air Force contract, the Fairchild Engine and Airplane Corporation then established a task force at the S-50 plant to examine the feasibility of nuclear aircraft and arranged with Wigner to receive scientific support from the Laboratory. Initial studies conducted by the Fairchild Corporation at the S-50 plant showed promise and, in 1948, the AEC asked the Massachusetts Institute of Technology (MIT) to evaluate the feasibility of nuclear-powered flight. MIT sent scientists to Lexington, Massachusetts, for a summer's appraisal, and they reported that such flight could be achieved within 15 years if sufficient resources were applied to the effort. In September 1949, the AEC approved Laboratory participation in an aircraft nuclear propulsion project. Weinberg was made project director and Cecil Ellis coordinator. Raymond Briant, Sylvan Cromer, and Walter Jordan later served as directors of the Laboratory's Aircraft Nuclear Propulsion (ANP) project.

Soon after the Laboratory acquired its nuclear propulsion project, General Electric took over the work of Fairchild and relocated it from Oak Ridge to its plant in Ohio. Although some Fairchild personnel transferred to Ohio, about 180 remained in Oak Ridge to join the Laboratory's aircraft project in May 1951. Among those who decided to stay in East Tennessee were Francois Kertesz, a multilingual scientist; Edward Bettis, a computer wizard before the age of computers; William Ergen, a reactor physicist; Fred Maienschein, later the director of the Laboratory's Engineering Physics and Mathematics Division; and Don Cowen of the Laboratory's Information and Reports Division.

Much of the Oak Ridge Laboratory's initial aircraft work focused on development of lightweight shielding to protect airplane crews and aircraft rubber, plastic, and petroleum components from radiation. Knowing a nuclear aircraft would never become airborne carrying the thick walls typical of reactor shields, Everitt Blizard and his team worked two shifts daily, testing potential lightweight shielding materials in the lid tank atop the Graphite Reactor. As research progressed, however, the Graphite Reactor proved inadequate to meet the level of research activity. To continue its shielding investigations, the Laboratory added two unique nuclear reactors to its fleet.

 First, in December 1950, the Laboratory completed its 2-MW Bulk Shielding Reactor at a cost of only $250,000. To build this reactor, the Laboratory modified its earlier Materials Testing Reactor design to create what became popularly known as the "swimming pool" reactor. This reactor's enriched uranium core was submerged in water for both core cooling and neutron moderation. From an overhead crane, the reactor could be moved about a concrete tank, the size of a swimming pool, to test bulk shielding in various configurations. A 10-kW nuclear assembly (named the Pool Critical Assembly) was subsequently placed in a corner of the pool to permit small-scale experiments without tying up the larger reactor.

The Laboratory standardized this inexpensive, safe, and stable design, which became a prototype for many research reactors built at universities and private laboratories around the world. Upgraded with a forced cooling system in 1963, it supplanted the Graphite Reactor (retired that year) and proved extremely useful for irradiation and study of materials at low temperatures.

A second Laboratory reactor resulting from the nuclear aircraft project was the Tower Shielding Facility, completed in 1953. Cables from steel towers could hoist a 1-MW reactor in a spherical container nearly 200 feet (60 meters) into the air. Because no shielding surrounded the reactor when suspended, it operated under television surveillance from an underground control room.

 Containing uranium and aluminum fuel plates moderated and cooled by water, this reactor helped scientists answer questions about radiation from a reactor flying overhead; it also helped researchers better understand the type and amount of shielding that would be needed aboard a nuclear aircraft.

Experiments indicated that a divided shield, consisting of one section around the aircraft's reactor and another around its crew, would comprise a combined weight less than that of a single thick shield blanketing the aircraft's reactor. Researchers, however, could never devise a reactor and shielding light enough to ensure safe flight. They even considered a "tug-tow" arrangement in which the crew and controls would be in a towed glider, separated from, yet tied to, the reactor by a long umbilical cable. The Tower Shielding Facility reactor later was upgraded, and shielding experiments recently took place there in support of breeder reactor development, long after visions of a nuclear aircraft faded from memory.

The Bulk Shielding Reactor and Tower Shielding Facility were designed to test materials that might be used on a nuclear-powered aircraft. For the U.S. Air Force, improved materials represented a means toward an end: a nuclear-powered engine that could drive long-range bombers to takeoff speeds and propel them around the world. To achieve this goal, the Laboratory designed an experimental 100-kW aircraft reactor as a demonstration.

This small reactor, operating at high temperatures, used molten uranium salts as its fuel, which flowed in serpentine tubes through an 18-inch (46-centimeter) reactor core. A heat exchanger dissipated the reactor's heat into the atmosphere. In 1953, the Laboratory constructed a building to house this experimental reactor.

To contain molten salts at high temperatures within a reactor, the Laboratory used a nickel-molybdenum alloy, INOR-8, designed by Oak Ridge researchers and fabricated at the International Nickel Company. Able to resist corrosion at high temperatures while retaining acceptable welding properties, the alloy was commercialized as Hastelloy-N by private industry (an early example of technology transfer) to supply tubing, sheet, and bar stock for industrial applications. The aircraft reactor also compelled Laboratory personnel to learn how to perform welding with remote manipulators and how to remotely disassemble molten-salt pumps. In addition, Laboratory researchers also devised two salt reprocessing schemes to recover uranium and lithium-7 from spent reactor fuel.

I have posted a layout diagram of the Tu-135 (see below). We also have mentioned the Tu-135 in the artwork sections of the forum (see also http://www.secretprojects.co.uk/forum/index.php/topic,10847.msg102015.html#msg102015 and  http://www.secretprojects.co.uk/forum/index.php/topic,1670.msg188818.html#msg188818).

The 12 page article covers the Tupolev Tu-135, Tu-119, Tu-95LAL (including reactor diagram and photo), American NX-2, Convair NB-36H, NX-2, Myashischev 3M-A, Samolet (Aircraft) 60, Samolet (Aircraft) 30 and others.

Hi!

No source, no name for the project. Was that a real projct or a fantasy? And if real, what does the "MI" stand for? Mitsubishi Industries?

Factory display model of the Martin M-331-10 supersonic (mach 1.5) Nuclear Patrol Seaplane concept, equipped with the GE AC-110 reactor and hydroskis.  The forward exhausts are for a pair of conventional (chemical) auxiliary P&W J-75 turbojets.

From my dear Scott,


here is the Convair XC-99 nuclear powered version;


http://up-ship.com/blog/?p=20433


Quote
A 1953 General Electric study for a Convair C-99 cargo plane modified with nuclear turbojet propulsion. The pusher-prop engines were removed from the wing and replaced with a 65,000-pound AC-2 nuclear powerplant within the fuselage. This was equipped with two separate jet engines, giving a total sea level static thrust of 35,500 pounds. Two additional conventionally fueled J77 engines were mounted in the wings for takeoff thrust. A lead and polyethylene shielded crew compartment weighing 20,000 pounds protected the crew, giving radiation doses of 0.5 roentgen per hour.

Here is a drawing that was simply identified as "Atomic engine transport".  It appears to be a C-133 with the "atomic" engine mounted in the fuselage hold.  Also note it only has 3 propeller driven engines, don't know if this was a mistake on the part of the artist.  San Diego ASM has more of the artists paintings in their online archives.  From looking at the photos it appears he may have worked for General Electric.  Below is a link to this gallery.  Don't know if was an actual project but thought I'd put it out there for people to see.

This concept has been discussed before. It wasn't a transport, as such, but an idea for a nuclear turbojet test aircraft. The engine shown here has one reactor feeding two separate turbojets; in this concept, only the starboard turbojet would be "live," with its own inlet and exhaust.

I suspect the lack of an inboard engine on the port wing is a "deleted for clarity" issue.

Hi! Myasishcchev M-60 nuclear bomber project.
http://testpilot.ru/russia/myasishchev/m/60/m60.htm

https://topwar.ru/77826-m-60-atomnyy-samolet-vm-myasischeva.html

https://ru.wikipedia.org/wiki/
"M-60
Originally, the designers saw the task of equipping m-50 special Motors Chief Designer a. m. Lyulka. But to the year 1956, it became clear that these engines have a number of problems: it was required to protect the crew from a large number of radiation, maintenance was supposed to occur remotely, strongly zagrjaznjalas' the environment Wednesday.
To protect the crew anticipated ispol'zovalat' dead lead capsule weighing approximately 60 tons. In the capsule would have maintained a positive pressure and Visual survey used television, radar screens and periscopes. Control of the plane partially fall on automatics. It was later invited to abandon altogether the crew as the plane could take off, climb, attack the target and return, but the idea was rejected.
For service of such aircraft needed special complexes. Required runway with a thickness of at least 0.5 m Engines were installed on the aircraft would automatically, immediately before the flight. Filling, delivery crew, suspension arms and so too should have been be automated because of the high radiation background."
"M-60 m
Due to the complexity of such land seaplane developed in parallel systems, m-60 m. All in all it was everything the same m-60, only the best engines raised above the ground. For take-off has been used a complex system of retractable underwater wings and gidrolyzh. These aircraft can be based not only in the southern latitudes of the USSR, but also in the North. At that time already possible to maintain such bases in unfrozen."

Hi! M-60 nuclear bomber two types.
http://tehno-science.ru/voennaya-texnika-710.html

②. M-60 with engines rocker "schema:
     takeoff weight is 225 tons, payload-25 t, altitude is 13-25 km, length — 58.8 m, wingspan — 30.6 m.

③. M-60 with a combined engine, flight characteristics are the same length: 51.6 m, wingspan is 26.5 m; are marked by numerals:
     1—turbojet engine; 2-Atomic Reactor; 3 — the cockpit. (Nuclear reactor was used as afterburner.)

④. combined turboreaktivno-Atomic engine:
     1-electric starter; 2-flap; 3-air duct straight through circuit; 4-compressor;
      5— the combustion chamber; 6-nuclear reactor; 7 — fuel Assembly.

Bottom picture shows M-30 nuclear bomber project with closed system nuclear jet engine. Red color part shows nuclear reactor. Primary heat transfer system(coolant :for example liquid Na, boiling temperature 882.8°C) is closed to confine radioactive substance. Engine intake air was heated by heat exchanger.

PWR : Pressurized Water Reactor. Reactor power control is conducted by control rod which insert to the fuel assembly to absorb nutron generated by chain reaction.

Oh you did it!! ;)

http://www.secretprojects.co.uk/forum/index.php/topic,855.180.html

http://energyfromthorium.com/2006/04/22/a-brief-history-of-the-liquid-fluoride-reactor/

Surprisingly this design has intermediate heat transfer loop. Coolant of primary heat transfer loop is fluoride salt with liquid fuel which generate fission heat at reactor moderated flow pass(center of the reactor which surrounded by beryllium metal refrection moderator that moderate nutron to increase chain reaction). Coolant of secondary heat transfer loop is Nak. Heat transfer between primary heat trasnfer loop and secondary heat transfer loop is conducterd by intermediate heat exchanger(IHX).
Engine intake air is heated by Nak to air radiator. Perhaps fatally heavy system for the aircraft.
Engine inlet Nak temperature is 1500°F(815.6°C).

"Heat generated in the fluoride salt was removed by a liquid sodium coolant loop and then dumped in an air-cooled heat exchanger. The ARE(Aircraft Reactor Experiment) showed that not only was the UF4 chemically stable in the solvent, but also that the fission products generated by fission formed stable fluorides in the salt mixture and did not plate out on surfaces. Another surprise was that gaseous fission products were removed essentially automatically by the pumping action of the reactor, accumulating in the pump bowl above the reactor. The fluid fuel had a very strong negative temperature coefficient, and the reactor could easily be started and stopped by changing the power demand on the reactor, without control rods. Despite its success, the engineers were not anxious to run the reactor for an extended period, since the “in-and-out” tubular configuration could not drain the salt from the core in the event of an accident. After 8 days the reactor was shut down.

Flushed with success from the ARE, ORNL engineers proposed the liquid-fluoride reactor as the baseline for the Aircraft Reactor Program and it was selected. Plans were made to build a “real” liquid-fluoride reactor that would operate at 60 MWt and would be of a flight-like configuration. This reactor was to be called the Aircraft Reactor Test, but the engineers referred to it as the “Fireball”
. The Fireball was a reflector-moderated design that used the NaF-ZrF4-UF4 fuel of the ARE, but was moderated by beryllium metal and cooled by liquid sodium-potassium eutectic (NaK). The NaK was planned to carry the fission heat to the turbojet engines that would provide thrust to the aircraft in flight."

Hi! Chinese site.
http://www.afwing.com/intro/nuclear_aircraft/nuclear_aircraft-1.htm
"This is the nuclear-turbojet engine СКБ-500 designed for the Milacherx.  Soviet engineers tested several types of nuclear-powered engines, including ramjet engines, turboprops, and turbojet engines.  Engineers have repeatedly tested the different transmission mechanisms of the engines, with a focus on verifying the heat transfer of the nuclear reactors. After extensive trials and repeated scenarios between the engine and the transmission system, the Soviet engineers concluded that the direct cycle of the turbojet is the best option.  Designers decided to use a direct cycle of energy transmission mode.  This method will use the reactor as the energy source of the power plant to replace the combustion used by the jet engine.
 In the direct recycle energy transfer device, the incoming air is first fed into the compressor of the turbojet engine and then passed through a duct that directs air to the reactor core.  This time into the air as a reactor coolant at the same time is heating up.  The air behind the core reactor reactor is returned to another air duct and is ejected from there through the turbine of the engine. "

Perhaps this engine also act as pure nuclear ramjet engine to shut control valve located front of the turbojet engine.

Engine structure: 1-electric start, 2-control valve, 3-ramjet housing , 4-compressor, 5-combustor, 6-flight control system, 7-fuel assembly

"Tupolev is well aware of the complexity of the task, the Bureau of the Group estimated that the manufacture of a prototype to up to 20 years time!  Because a lot of technology is still immature or there are research and development problems, so the aircraft really shape to be time.  They considered the first experimental nature of the nuclear power as a supporting power of the aircraft until the late 1970s or early 80s to launch.  The purpose of the current program is to explore the feasibility of the technology.  At the end of 1955, the designers began the first phase of the design and testing of a small nuclear reactor.  In March 1956, the Soviet ministerial meeting designated Tupolev as soon as possible to produce flight test platform.  Tupolev engineers decided to convert the existing chart-95M bomber into a "flying nuclear laboratory".  The final figure -95LAL turned out.

 By 1958, after the nuclear reactor was installed, the aircraft was ready for ground phase testing.  During the summer of 1958, the nuclear power plant began testing.  Shortly after the test, the designer was surprised to find that the reactor power reached the previously set requirements.  The expert group immediately decided to begin preparations for the flight pilot phase.  Between May and August 1961, Figure -95LAL completed 34 flight test missions. "

"All of the test flight, Figure -95LAL nuclear power plant are in a closed state. The main purpose of the flight is to obtain the flight parameters of the modified aircraft to verify that the machine is suitable as the ultimate nuclear power plant equipped with aircraft.  A large amount of liquid sodium, beryllium oxide, cadmium, paraffin and fine steel are used to make the radiant cockpit - the core part that protects the pilots from lethal radiation.  The result is so exciting Tupolev Design Bureau.  It is estimated by the instrument that the radiation level in the cockpit is low, which paves the way for the design of a new body that can meet the actual requirements.  The next stage of the program is to produce a new verification machine.  This design from the outset will be nuclear energy as its main driving force.  This new verification machine number 119 is designed on the basis of Figure -95.

 The main difference with the general figure -95 is that there are two of its four engines for the NK-14A turboprop engine with new heat exchangers installed. NK-14A is a very similar direct-loop engine.  The main difference is that the air through the compressor, and did not lead to the reactor, but directly to the heat exchange system.  At the same time, the heat generated by the nuclear reactor passes through the fluid to the heat exchange system.  The combination of these two forces will allow the engine to produce the thrust required.  The other two outboard engines are NK-12M. "

"At the same time when the Kuznetsov Design Bureau developed the engine, the schematic of the 119 aircraft was completed.  The inside of the drawing shows that the internal magazine will place the reactor.  From the reactor to the engine connecting pipe through the main body, and then forked up to the two wings, and ultimately directly connected to the two NK-14A engine heat exchanger.  Tupolev estimated that by the end of 1965, 119 would take the airport takeoff and landing tests.  After the test, the mixed engine group of No. 119 was replaced by four all-in-one NK-14A engines. The replacement of the NK-14A is different from the earlier test flight used.  New engine changed from Figure -114 Business flight using NK-14A. However, the original drawings did not make any changes to the 119 facelift engine.  Perhaps this episode seems to imply that the whole plan is stalled.  In August 1966, due to budget constraints and major design bureaus took over the design task of developing new conventional aircraft, time-consuming, and not very safe figure-95LAL project came to an end.  The cancellation of the plan did not mean that the Soviet Union had terminated its nuclear-powered aircraft research project.  Because the same period, the other nuclear-powered aircraft project did not dismount.  For example, later on the implementation of No. 117 in the 120 project.  120 is different from 119, it is nuclear power supersonic bomber project verification machine."
Around this project, the Soviet Union made a lot of research.  The Soviet Union will focus on the new turbojet engine research and development and re-layout of the nuclear reactor system research.  The newly designed system is required to provide more protection to crew and airborne avionics systems.  120 is expected to install the two new turbojet engines designed by the Kuznetsov Design Board.  This time the installation of the reactor is different from the 119 practice, but installed in the tail.  The reason is simple, the reactor from the cockpit farther the better, is to reduce the radiation on the crew of the most vulnerable to the law.  The crew consisted of pilots, co-pilot and navigator, and their seats were placed in a heavy, confined, radiation shielded cockpit.  120 with 45 degrees swept wing, rear swept wing and front triangular landing gear design.  From the appearance point of view, compared with the previous use of the traditional power of the Tupolev series bombers compared to 120 does not seem bloated.  The goal of the Tupolev Design Bureau was to complete all R & D and testing work in the late 1970s and then put it into use.  Unfortunately, 120 did not wait until that day.  And 119 the same reason, 120 project in 119 after dismount was canceled.  This plane did not even made the prototype of the 120 long-range fighting dream can only dusty in the yellowing of the design drawings.

 Tupolev design bureau has made the next attempt.  It is 132.  But 132 is generally considered to be an attacker, not a bomber required by the plan.  The installation of the power plant is similar to that of 120, and the reactor is mounted at the tail, before the two turbojet engines.  And the entire power system all on the tail, unlike 119 and 120 there are still many auxiliary parts installed in the machine throughout. This engine can be operated either by conventional kerosene and by nuclear power.  However, the Soviet designers only intend to use kerosene for aircraft takeoff and landing. All kerosene is poured into a special cabinet type container in front of the reactor.  The other parts of the aircraft are almost the same as 120, but the right inside made some changes.

(Engine is like this?)
http://www.secretprojects.co.uk/forum/index.php?action=dlattach;topic=855.0;attach=575109;image
(Or like this? In this case air route to conbustion chamber or to mercury to air heat exchanger is selected by control valve?)
http://www.secretprojects.co.uk/forum/index.php?action=dlattach;topic=855.0;attach=575139;image

132 is expected to use delta wing, which is likely to be considered an important reason for attack aircraft.  The tail is also used in the back sweep design, the level of stability in the wing roof.  Technical problems quickly let 132 into a dead end.  132 was canceled in the mid-1960s.  The last effort of the Tupolev Design Bureau was a plane that had not yet been completed.  The aircraft is designed to be a supersonic bomber designed to compete with the US-based B-58 medium bomber.
 However, by the funding, technology, security and other factors under the influence of the Soviet Union in the late 60's nuclear power aircraft enthusiasm finally exhausted.  The Soviet Union decided to end all the projects launched, while giving up the results of the feasibility study.  In general, the reason for the end of the plan is that the nuclear strike capability of the intercontinental ballistic missiles on the Soviet nuclear submarines is more accurate and cheaper (relative to the development of nuclear power aircraft).  For the implementation of the planned economy of the Soviet Union, to strengthen the already underwater nuclear strike capability than to continue in the nuclear-powered aircraft this project burn more cost-effective. "

Of course No.3 drawing is little strange. Condenser(heat exchanger) should be located at front of the turbine.
I imagine that NK-14A engine shape is almost same as NK-12 turboprop engine. Nk-14A had condenser(mercury to air heat exchanger) instead of NK-12 conbustion chamber. Mercury to air heat exchanger must be very large compared with conbustion chamber.

Hi! Weapon system 125.
https://en.wikipedia.org/wiki/WS-125
http://www.hitechweb.genezis.eu/pohon.htm
http://www.hitechweb.genezis.eu/pohon1a.htm

"The WS-125 was an American super long-range strategic bomber project during the cold War to develop a nuclear-powered aircraft, which was scheduled to be designated the B-72.
In 1954, the United States Air Force (USAF) issued a weapons system requirement for a nuclear-powered bomber, designated WS-125. In 1956, GE teamed up with Convair (X211 program) and Pratt & Whitney with Lockheed in competitive engine/airframe development to address the requirement.
In 1956, the USAF decided that the proposed WS-125 bomber was unfeasible as an operational strategic aircraft. Finally, after spending more than 1 billion dollars, the project was cancelled on March 28, 1961.
Powerplants
Two General Electric J87 turbofan engines were successfully powered to nearly full thrust using two shielded reactors.

"Proposed projects
 In 1955 , two teams were formed, with the task of furthering the study of the new bomber.  These were formed by Convair and General Electric , and Lockheed and Pratt & Whitney .  Subsequently, a project was presented also by Douglas .

 In general, these were projects with very innovative ways.  Lockheed opted for a radically new project, while the Convair decided to start from an existing model, or at least under development (special consideration were the projects of the Convair B-58 and ' XB-70 ).  However, all aircraft should have been driven by a variable number of turbojets .

Hi! Is this a Douglas WS-125A proposal?
http://www.aviationmodels-online.com/Featured_model9/Douglas_Atomic_Bomber.htm

"Douglas Model 26 ‘Atomic Bomber’
 A wooden, in-house Douglas model of a proposed nuclear powered bomber for the USAF. The layout was clearly designed to keep the crew as far away from the engines as possible!  It was possibly a contemporary of the Convair NX-2 project, proposed in response to requirement WS-125A, dated 1954.  The Aircraft Nuclear Propulsion programme was abandoned in 1961, so the model probably dates from the mid/late ‘50s."

I can't see additional two J-75 engines. ;D

I remember that I used to see this aircraft somewhere in this forum.

Hi!
Convair blueprint for the nuclear-powered Princess. Photo via Scott Lowther

https://warisboring.com/her-majestys-nuclear-seaplane-7043b94b09aa#.oc7uq1ct8

"So when the U.S. Navy approached Convair with a really weird idea, the San Diego aircraft maker responded with alacrity. If the Princess flying boats were brought to America, asked the Navy, could Convair convert them to nuclear power? Yes, said the company, and drew up blueprints for the modifications. Like the Convair Crusader, the nuclear Princess would be a testbed for atomic-powered flight and crew shielding.All that room prepared for Imperial dignitaries and posh travellers would accommodate a Pratt & Whitney liquid-metal-cooled reactor, a heat exchanger and some serious plumbing to run superheated (radioactive) air into special P&W gas turbines; the “hot” gas would replace gas heated by jet fuel once the big plane reached cruising altitude.

Four turboprop engines would get the seaplane airborne while two nuclear turboprop engines(Nuclear-chemical P&W T57 turboprop engine) would take over during cruise. The great weight of the nuclear power system played to the flying boat’s strength — it’s easier to float great weights than land them on runways. The Air Force’s planned nuclear bomber would have required a 3-mile long runway, as long as the Space Shuttle’s."

If an atomic airplane falls, it'll be a catastrophe. The crews rescue will be very difficult. A resident around the fall spot has to take refuge for an extended period, too.

Unfortunately, no.  The model appears to have been modified at some time from the "Hughes Interceptor" concept shown below.  Mention of GEN Laurence Kuter as CINC NORAD in the caption would date the photo as having been released between 1958 and 1961.

Super!! I lost it.
And Nuclear Navy sea plane powered by CCR(compact-core reactor) which proposed by the Nuclear Development Corporation.
This nuclear reactor had solid fuel which cooled by liquid metal.

Also modified AC-110 (perhaps direct cycle)power plant and AC-107 power plant installation was studied.(AC means air cooled reactor?)

Hi! B-52G XNJ140E-1 nuclear turbojet engine test bed and nuclear powered supersonic aircraft design.
XNJ140E-1 engine is very large or this picture shows LF-2 engine?

XNJ140 was a nuclear engine with single X211 turbo machinary.
Each X211 air intake diameter : 1.4m.
J-57's diameter is abut 1m.

GE also investigated liquid-circulating-fuel nuclear reactor called LF-1 to LF-6. I think that LF means liquid fuel.
Intermediate heat transfer liquid of this reactor is NaK. Engine intake air was heated by Nak/air heat exchanger.
This report said that Nak has fire hazard.

I find this aircraft as Douglas Model 26 Atomic Bomber in Tony Buttler AMERICAN SECRET PROJECTS BOMBERS, ATTACK AND ANTI-SUBMARINE AIRCRAFT 1945 TO 1974, page 94.
He said that "It carries a Tactical Air Command crest on its fin". He also told about Hughes mach 3 interceptor.

Hi! Early nuclear powered aircraft concept from "Popular Science In October,1951".
The frist picture shows indirect nuclear reactor system. Primary coolant is liquid metal and secondary coolant is water. This system is same as Liquid metal cooling fast breeder reactor(LMFBR). But generally LMFRB has intermediate cooling system to protect reactor from sodium/water reaction which occured in sodium/water heat exchanger(Steram Generator) by heat transfer tube water leak.
The second picture shows also indirect nuclear reactor system. Coolant is water. This system is same as Boiling water reactor(BWR).
Perhaps the cooling water is maintained at about 75 atm (7.6 MPa, 1000–1100 psi) so that it boils in the core at about 285 °C (550 °F) same as BWR), and became heavy weight system.

Yeah, that was everything awesome about the 1950's in one crazypants idea. Then came the 1960s with it's horizon-contraction... sigh...

I am just grateful that these nuclear powered aircraft did not come to be, we have enough problems from dropping conventional aircraft.

Does anyone have more information on the first Northrop nuclear-powered flying wing proposal?

I would say something about the Convair nuclear seaplane proposal but I don't think it would be off to assume you actually know more than me.

It's just stuff from the Convair Advanced Designs books.

I imagined at least Orion would have them already.

A lot of us have those books. Some of us even have some of the original reports and diagrams. But your original statement remains confounding. English not your language?

Well...maybe I'm making too many assumptions. Basically, what I meant was that I felt that you probably knew more about the Convair seaplane than I did, so I didn't feel there was much I could say to contribute to the topic myself. And it felt wrong to ask when I didn't have something to provide myself, though I guess I've provided maybe one or two things on other boards since then.

I was probably confused, and I was also in a rush, so that would probably contribute to it. Sorry about that.

Perfectly fair to ask. There are, however, three generally accepted rules about asking for stuff;
1: Go through the thread and make sure it hasn't already been asked & answered
2: Don't get pushy and demanding.
3: Don't ask for high-rez scans of books and articles that are currently available for purchase.

There is no quid pro quo demanded, nor can one be reasonably expected. There is always going to be a "hierarchy" where a few people have mountains of archives and a lot of people have very little.

That said, feel free to put a few hundred thousand dollars into my tip jar.
