Skybolt - Did you see the 260" ICBM thread? Interesting talk about a super heavy lift ICBM. My dream would be more limited just 120" and about 110' for MMIII replacement and conventional prompt global strike :D

Global strike of 250 MT
if 206" ICBM use TEN B41 nuclear bomb each 25MT as payload
General LeMay would be delighted…

This was from another thread I started might interest people here:

From what appears to be a book abstract by Maurice F. Crommie. His website has this in his resume

Dec 1962 - Sept 1971

Consulting Engineer, Senior Scientist and Project Leader in strategic nuclear weapon design at General Electric, McDonald Douglas, Stanford Research Institute, Conductron Corporation and Avco Research and Advanced Design.

Jan 1960 - Dec 1962

Senior Engineer and Heat Transfer Specialist in rocket nozzle design and space capsule re-entry at TRW and Avco Research and Advanced Design.

March 1955 - Dec 1959

Aerothermodynamicist / jet engine designer

Link to his bibliography - http://home.olemiss.edu/~mcrommie/

“The subject of our paper was multiple warhead delivery systems. The title of our paper was “CLAW”, which stood for “Clustered Atomic Warheads”. We delivered this paper at a top secret restricted session of AMRAC at the secure Naval Station in San Diego in 1962. It was the first paper of its type advocating multiple warhead payloads. MIRV hadn’t been invented yet. The capability for Multiple Independently Targeted Re-entry Vehicles didn’t exist in 1962. Our system could deliver multiple warheads, but only on a single target in a circular or elliptical pattern. This was an advance in the state of the art at that time.

[snip]

“Following the success of our AMRAC paper, I was promoted to Project Engineer for the design of a heavy payload system, 39,000 pounds on top of a Titan III missile. The mission was to negate the Leningrad SAM defense system to allow our B 52′s access to the target. My liaison officer was a U.S.A.F. major, who was a B 52 pilot. His idea was that when we softened up the target with our nuclear barrage, he would fly in and finish it off.

“Me and my team designed a three tiered payload with 13 one megaton Mark 11 RV’s in each tier (39 total) which would be spun out in space and impact the Leningrad defenses in three concentric elliptical rings. Our liaison officer was ecstatic, his bomb run would be unopposed. What he didn’t seem to realize was that there would be nothing left to bomb after we laid down a barrage equal to 2000 times the weapon that destroyed Hiroshima.”

Back To Titan booster

USAF Space and Missile Systems Organization (SAMSO) and The Aerospace Corporation,
made during 1965 to 1968 Minimum Cost Design studies
as low cost alternative to Titan III family
Also they studied also to replace the Solid booster of Titan IIIC
With pressure fed Strap-ons or Hybrid strap-ons wat exceeded the Soild one.

The Aerospace Corporation proposed tow different pressure fed liquid fuel strap-on concepts
United Technology proposed Hybrid Booster
TRW proposed Low-cost throttleable pressure fed single-chamber engine

In end the Minimum Cost Design studies died quiet by politic

A simple question. Does recovery at sea of Titan III Solid Rocket Motors was ever considered ?
Could someone point me to a study ?
I can't believe Martin Marietta (or the SRM builder, whatever company was that ?) never did such a proposal.
I would say that proposal should have been done somewhere between 1964 and 1974 or so.

For the sake of comparison, ESA tried to recover Ariane 5 own solids for studies only.

It's a reasonably accurate Zenith Star Launch System model, probably based on the one painting and one drawing that were published in Aerospace America way back when.

The webpage, and thus the photos, is more than a decade old, probably from sometime in the 90's. Which means film photos on a flatbed scanner. And good film camera shots are a lot harder to get than good digital camera shots, sinc eyou can get a billion digital shots for the cost of a single roll of film.
 
The MDD Barbarian model as built by Erik Anderson matches Mark Wade's description. If you know more about Barbarian, I'd honestly like to know.

As far as I know, both McDonnell-Douglas and Martin Marietta proposed heavy launchers for SDI. According to Mark Wade, they were both tagged with the 'Barbarian' moniker.

Astronautix is just a space version of wikipedia, it is not absolute reference.

And with its own unique problems. At least with Wikipedia, if there is a glaring error, you can fix it. On Astronautix, if there is a glaring error, it's probably never going to get fixed. (Then again, on Wikipedia people who think they know stuff can introduce their own errors.)
 
Just the same, I was aware both McDonnell-Douglas and Martin Marietta had proposed heavy launchers for SDI. It was too much of a business opportunity for either company not to jump in. Astronautix confirmed that, and - news to me - with the same name: Barbarian. I can't find any other references than OBB's site and Astronautix.

If you know more, and are allowed to share...

...Pbbbbt. Given the choice, I'd trust Mark Wade on the majority of common articles over Wikipedia. At least with Astronautix, you don't need to worry about the possibility that some prepubecent troll can come across and screw with the facts as well as other acts of vandalism, just to mark their scrawl. Ergo, just because Mark doesn't let the inmates run the asylum over on Astronautx doesn't mean it shouldn't be used as a resource. In fact, over the years I've found that a *lot* of the Wiki articles on Space Exploration have had whole sections lifted from Astronautics and just C&Pd, half the time without proper accreditation.

[shakes head in totally dismay]

I wouldn't because I know better, and that is the issue, it isn't any better. One can find just as many errors in it as wiki and it has the author's bias in it. Also volume does not equate to quality.
 
Found another reference for McDonnell-Douglas proposing a heavy launcher for Zenith Star.

Zenith Star Launch System Stafford, Larry; Rendine, Michael J. Aerospace America (ISSN 0740-722X), vol. 28, Sept. 1990, p. 40-43. <blockquote>The Zenith Star Launch System (ZSLS) will be used by the SDIO to loft the Alpha Laser and its Large Adaptive Mirror system to orbit. ZSLS performance requirements were rendered especially severe by the weights of these systems, which involved not only the 40,000 lbs of the laser and 15,000 lbs of the mirror, but the weight of laser fuel, laser coolant, beam-control system, target acquisition system, and laser pointing/tracking system. The Titan IV launch vehicle could not have lifted more than 40,000 lbs to LEO. The requisite 100,000 lbs will instead be boosted by a composite launch vehicle consisting of three Shuttle SRBs surrounding a cluster of six Delta II liquid-propellant first stages, and an air-started Delta II first stage. The payload fits within a Titan IV fairing. </blockquote> Keywords: HIGH POWER LASERS, LARGE SPACE STRUCTURES, LAUNCH VEHICLES, SPACEBORNE LASERS, LIQUID PROPELLANT ROCKET ENGINES, MIRRORS, PAYLOADS, SPACE SHUTTLE BOOSTERS

interesting find by Hexham
index.php


A Titan I with Centaur as Second stage, here for X-20 Dyna-Soar Phase Alpha booster study.
for Step IIA consider Orbital flights here:
the Titan I first stage add 105000 lb of Lox/RP-1 fuel and the engines are uprated to max 400000 lb. thrust.
as second stage Centaur B with two RL-10B engine
because this Titan-Centaur is on limit of size and thrust they study also a smaller version
with 360000 lb. Thrust and 66000 lb. additional fuel in first stage.

Titan IIIG.

EDIT: No wait, Titan IIIG was the first of many proposals by Martin for "fat core" Titans.

IIIG would have been a 180" diameter core , compared to the later 192" (16 ft) core proposed for Titan IIIL-1207-4 (Spread) for the Grumman H-33 Orbiter or the 196" diameter core proposed for 'straight' Titan IIIL 2/4/6.


IIIG would have had option of two UA-1207 or UA-1565 (156" diam 5 segment SRM) boosters, and would have had four engines.


No idea if these were stock LR87s or the 'cut down' single chamber LR87s of only 226 klbf used in Titan IIIL-1207-4 (Spread).

Titan III-L, here in configuration 1207-4 Spread. 5 Aerojet General LR-87s
Click to expand...


If you read the document that's from, you'll notice they're an as yet uncategorized LR87.


They had an expansion ratio of 12 (vs 8 of the ones used on Titan III), and were single chamber, not dual chamber

Thrust was also substantially lower as a result.
 
Hi ,
What fat body Titan designs were there in the the Fifties? The US and UK used a common diametric standard for the missile,
The UK did a lot of work for the 15' (180in) as well as the16' (196in) and the 14' (168in) these were dedicated SLV variants.
Prior to Blue Streak 15' and 16' missiles were suggested (before 1954) with the observation that the 15' would be rail transportable. One source only for the rail transportability at PRO Kew.
There must have been work on a fat body Titan missile and SLV variants must have been considered in the fifties?

The Titan I was only briefly look at as an SLV much less a wide body. Titan II contract was only started in 1960. Transportability was a prime consideration. So, there was no work in the 50's on wide body Titan.
 
on Fat body Titan been considered in the fifties

there was the 1957 Titan-C proposal
based on Titan I hardware. it feature first stage 4 meter ø with 4 x Engine LR-87-3, as second stage the Titan 1 first stage.

also I remember vaguely on Titan-1 with Polaris SSLB as stage 3 and 4 for Interplanetary mission.
 
From ABMA's Proposed National Integrated Missile and Space Development Program, from March 1958
Titan I as Space launcher with payload 450-1400 kg
Titan I with Polaris SSLB as stage 3 and 4. Payload 1400-2300 kg
also they proposed a Titan I with this feature:
First stage recoverable; 2 and 3 stages with N2H4-F2 or H2-O2 fuel. Payload 2300-4500 kg

From NACA Working Group's Recommended Space Vehicles, July 1958
Titan I with N2H4-F2 upper stage with 53 kN engine. Payload 1400-2700 kg
Uprated Titan I, first stage recoverable. with high-energy upper stage. Payload 2300-4500 kg

but already in 1959 under NASA the proposals for Titan I as Space launcher is disappear.
while the Air Force's Titan C proposed by the Glenn L. Martin Company as a launch vehicle for Dynasoar.
The first-stage was 4 meters in diameter and was powered by four Aerojet ICBM engines of 667 kN each.
The second stage was powered by two of the same engines but equipped with larger nozzles for high-altitude operation.

I just wonder about the designation Titan-C
because there Two titan rockets with that designation, this all O2-RP-1 fuel and another with Titan II first stage and H2-O2 second stage.
or could it be that here was made error in identification ?
that the Titan II first stage and H2-O2 second stage is in realty the Titan I with centaur for Dyna Soar ?

nope, was consider as Dyna Soar launcher.


i found on Titan-IIIM new variant, a Titan-IIIM(LDC)
i have no idea what LDC means, the paper* show only that carry more payload in orbit
while Titan-IIIM carry 36000 lb. in 125 n.m orbit at 90°, a Titan-IIIM(LDC) brings 48300 lb. in same orbit
