From the Russian magazine,Авиация и космонавтика,

but I don't know what is exactly the issue,there was a Recce Project version of Su-34,who
heard about it ?.
 
Hi,
are there any images of s-60/t-60

Placement of weapons and location for cameras on Su-12 (RK)

Posts number 22 and 59 show a Soviet airplane designed fo rthe same role as the notsi Blohm & Voss 141 and Focke-Wulf 189 recce airplanes.

Odd how Soviets hung bombs aft of the centre of gravity. ... aft of the wings' rear spar.
That would create severe nose-down pitching problems immediately after dropping bombs.
Even with far more powerful engines, this Focke-Wulf 189/BV 141 clone proved a dud.

The bombs are placed rather far back in the fuselage booms to make room for the main landing gear bays. They could have been under the center wing section, but performance would have dropped quite a bit.
The flight characteristics of the craft was satisfactory at the end of the tests, it is just that no one wanted a glasshouse reconnaissance aircraft in the late 40’s; much less a propeller one.
 
Hi! Sukhoi T-5.
http://www.ussr-airspace.com/index.php?main_page=product_info&cPath=28_39_38_97&products_id=1558

"In the air regiments of the Su-11, they served until the middle of the 70-s and were gradually superseded by the MiG-23P and the MiG-25. The few Su-11s were the transitional machine between the first in practice Sukhoi Design Bureau supersonic interceptor and the more advanced Su-15, which earned the title of "classic" in air defense. The rapid withdrawal from serial production, which was caused by problems with the reliability of the Su-9 marines, did not bother P. O. Sukhoi, but on the contrary, stimulated him to develop a new machine.

Naturally, the search for an alternative power plant, and more than that of the AL-7F-2, was started. Almost at the same time, at the turn of 1959, the design bureau began to design a heavy T-37 fighter with a TRX Р15-300 and an interceptor P-1 with a power plant consisting of one AL-9. In the same period, tested and aircraft T-5, which was the development of T-3-51. T-5 retained the wing, tail, nose and central parts of the base aircraft, but differed from T-3-51 in a power plant consisting of two P-11F-300 engines designed by the Tumansky Design Bureau (similar engines were installed on the MiG-21). In 1958, the tests of the T-5 began. At the same time, the new machine was not considered by Dry as a ready interceptor, it was an exclusively experimental aircraft. T-5 had a lot of limitations due to rear alignment, so it was not possible to fully disclose its capabilities in all modes. One thing was certain, the new aircraft had a great power supply and rate of climb.
Interestingly, a similar evolution took place some time later through the experienced single-engine interceptor E-150 of the OKB A. I. Mikoyan, on which the Р15-300 engine was replaced by a R-11F-300 engine. The new Mikoyan aircraft received the name E-152, and its scheme was identical to that of the T-5 (a common axisymmetric air intake in the forward fuselage, two engines in the tail section and a delta wing of small elongation). In addition, at the end of 60-ies in China built a heavy interceptor, also performing it on the type of T-5 and with the same engines P-11-300. As you can see, the T-5 scheme was rated as very promising, but P. O. Sukhoi went even further."

"In August 1953, the Council of Ministers of the USSR issued a directive to launch the development of a supersonic fighter and interceptor, with wings or delta wings, capable of competing with the American F-100 Super Sabre. The Sukhai OKB-51 responded immediately and proposed two projects for each aircraft: the T-1 and T-3 with delta wings, and the S-1 and the S-3 with soaring wings; of course both had differences. It was the S-1 that was chosen. It had a 60-degree soaring wing, a 7500 kgp Lioulka AL-7F post-combustion turbojet, and an ejector seat from the same manufacturer as the aircraft.

Design studies of the S-1 ended in 1954, and by July 1955, a prototype and a static test bans had been built. The prototype made its first flight on September 7, 1955 with A.G. Kochetkov, then a test pilot from Lavotchkin, at the controls. The aircraft's 12th flight was exceptional: the test pilot managed to set a new speed record of 2170 km/h in April 1956, when the required speed in the specifications was 1900 km/h. Even before the start of the acceptance tests, and following the performance of the manufacturer's tests, the Council of Ministers of the USSR decided to order a small series of Su-7 fighters, the name given to the standard version of the S-1. On June 24, 1956, the S-1 made its first public appearance at the Touchino show."
 
Hi! T-3 Delta wing supersonic interceptor.
1. The first flight : 26th April 1956.
2. On 24th June 1956, the aircraft made public debut participating flypass at Tsushino airfield in Moskow.
3. From the flight test report by the manufacture.(engine lacking bleed valves)
(1) Top speed in level flight in full afterburner at 12000m : 2100km/h.
(2) Ceiling 18000m.
(3) Range at 12000m : 1400km (1800km with drop tanks).
(4) T-3's Almag-3 fire control radar had two antennas, the upper radome was for the reseach antenna and the lower
radome for the guidance antenna (located inside of the air intake).
(5) Armament : two K-7L missiles.
(6) T-3 was unable to reach the specified maximum speed(Soviet airforce requirement 1900-1950km/h) and altitude
with a fixed area air intake and the existing radome arrangement and poor engine performance.
T-3 could not do better than 1830km/h and ceiling 18000m(Soviet airforce reqirement : 19000-1950m).
(7) T-3's never-exceed speed was limited to Mach 1.83 to avoid engine surge.
(8) Modified AL-7F engine's bleed valve reduced available thrust at speed exceeding Mach 1.6.
(full military power 7500kgp⇒6850kgp, full after burner power 10000kgp ⇒8950kgp)

Hi! T-58VD.
http://www.airwar.ru/enc/xplane/t58vd.html
"The T-58VD is an experimental fighter with a short takeoff and landing, developed in the Sukhoi Design Bureau. This machine had nothing to do with the improvement of the Su-15 itself. It was used as a flying laboratory for the program of creating a shortened take-off and landing T-6-1, from which the Su-24 front-line bomber leads."

Hi! T-6-1.
As the need arose to replace the Yakovlev Yak-28 Brewer making up the backbone of the Soviet Air Force's tactical bomber fleet since 1960, the Sukhoi Design Bureau began development of a twinjet tactical bomber known in-house as the T-6. The first prototype (called T6-1) flew in June 1967, featuring delta wings and four lift-jets buried in the fuselage to improve field performance. However, the weight penalty imposed by the lift-jets was deemed unacceptable and the aircraft was radically reworked to feature variable-geometry wings, becoming the Soviet counterpart to the General Dynamics FB-111. The resulting T6-21 entered flight testing in May 1970, subsequently entering production and service as the Su-24. The bomber underwent a progressive refinement and development process, spawning dedicated reconnaissance and ECM variants. To this day, the Su-24 remains the principal Russian tactical bomber. Apart from deployment in East Germany and Poland in the Cold War days, the type has participated in "hot" conflicts as the Afgan War and the First Chechen War.

Hi! PT-7.
(1) PT-7 was a modified PT-3 No.2 aircraft. PT-7 had a AL-7F-1 engine.
(2) Basically PT-7 and PT-8 were same aircraft. Aircraft factory No.153 in Novosibirsk manufactured three PT-8.
(3) The installation of a new radar needed new forward fuselage, the tracking antenna was moved down to the air intake lower lip and enclosed by a conical radome.
(4) The maiden flight : the end of Jane 1957.
(5) Through flight test, it became clear that fixed shape air intake was not enough Mach 2 flight.

Hi! T-43.
(1) Sukhoi planned T-43 experimental fighter which increase PT-7 flight performance, using two rocket boosters and variable air intake (by movable axisymmetrical conical centerbody).
(2) The maiden flight : 10th October 1957.
(3) T-43 climbed to 21500m and marked 2200km/h(Mach 2.06) without rocket boosters.
(4) Then T-43 with Ts D-30 radar and RS-2-US AAM, without rocket boosters became Su-9.

One of the PT-8 was converted to T-47 which had only two cannons at the wing root. Later abandoned. The maiden flight was 1958/1/6.
Also one of the PT-8 was converted to PT-8-4 which carried only two missiles. Later this aircraft was called as T-47,too.
The maiden flight was 1958/2/21. This T-47 was the base of Su-11 interceptor with RP-11 radar and K-8(R-8) missiles.
Another PT-8 was converted to T-39 and converted to T-49 private venture experimental aircraft which could install larger diameter radar at the nose to have side air intake.

Hi! T-58D and Su-15.
(1) Sukhoi began construction of private venture single engine T-58(Su-11M) in September 1960.
(2) T-58 had rectangular side air intake and Su-11 wing/tail stabilizer.
(3) But PVO requested twin engine fighter with area-ruled fuselage.
(4) Then Sukhoi offered twin engine T-58D and PVD accepted this design.
(5) T-58D had two R-11F2-300 engines. The wing design was from Su-11.
(6) The maiden flight of T-58D was on 30th of May 1962.
(7) The main problem of T-58D was short range compared with requested value by PVO.
(8) Sukhoi modified T-58D-3 by applying non area rule fuselage to increase fuel tank volume.
(9) Modified T-58D-3 became the prototype of Su-15.

One Su-9 was used for research on side force control.
For a normal airplane, it is necessary to tilt the aircraft when turning to the left or right, but in this airplane, the fully floating control surface was set vertically at the nose, and the direction is changed while maintaining the horizontal attitude by the operation.
This research aircraft was called L.02-10. The L.02-10 had control surfaces installed above and below the nose, but the control surfece on the upper surface obstructed the pilot's view, so the flight test was conducted with the control surface on the upper surface removed.

Hi! T-58M.
http://www.alfa-industry.ru/news/104/101284/
"Already in 1964, the work received a new T-58M, which was associated with the adjustment of the technical task for the new aircraft, which the military began to consider as a low-altitude attack aircraft, which had to meet the requirements of the possibility of shortened takeoff and landing. Another requirement on the part of the military was to ensure a low-altitude flight at supersonic speed, it was necessary to overcome the air defense zone of the likely enemy. On the plane in this version proposed to install in the middle part of the fuselage at once four lifting engines RD-36-35 (short takeoff and landing mode). And the full composition of the power plant also assumed the presence of two engine TRDF R-27F-300. The flight weight of the new aircraft was estimated at 22-23 tons.
Since the spring of 1965, the Sukhoi KB has been undergoing full-scale work on the design of the T-58M aircraft, which at that time was held as a low-altitude attack aircraft, capable of also acting as a fighter. Curiously, in the same 1965 it was decided to change the layout of the future aircraft, in which the pilots were placed in the cockpit side by side, and not tandem after each other. Later, this crew deployment will be implemented on the Su-24 serial front-line bomber, and then on the modern Su-34 fighter-bomber, which came to replace it. At the same time, the T-58M was moved to a similar layout due to the fact that the cross-sectional size of the antenna of the Orion sighting station, which was located in the bow of the projected aircraft, increased."

What is the relation between these two aircraft?

The top one is T-58M, a tactical strike aircraft.

Lower drawing is of a very brief development (possible joint project?) of the T-58M with lift engines in the fuselage for STOL operations.

Hmmm, I didn't know that. Is it possible that it was a NATO designation, or an internal designation for a projects?
 
According to page 77 of SOVIET SECRET PROJECTS FIGHTERS SINCE 1945, TONY BUTTLER & YEFIM GORDON,
(1) Advanced interceptor development project based on the original Su-15 was initially called T-58PS.
(2) T-58PS was studied in1972 and 1973.
(3) T-58PS was given new large wings of ogival form based on the first T-10(Su-27) prototype.
(4) TsAGI confirmed that the T-58PS performance and agility would be far superior to the basic Su-15.
(5) During the later stage of the project's life the official correspondence between the design bureau and it's customers referred to it as Su-19.
(6) Later Su-19M planned to have new R-67-300 engine.
(7) But Su-19M did not have look-down/shoot-down radar. This brought the end of the Su-19 series.
 
Please cease and desist with this ragbag topic. It goes against the principles of the forum.

Most of these recent posts are on well-known designs we already have existing topics on. In at least one post I have deleted, the source was this forum itself! Quite what the purpose is of putting this material here, I don't know - it's quite exasperating.

f you have contributions to make, POST THEM IN THE SPECIFIC TOPIC!

If there's no specific topic, MAKE ONE!

It really shouldn't be that hard.
