Looks close to Tupolev '130' '136' and '137' 'Star' (Dyna Soarski) test article, but you know - all these T test benches looks damn the same

 

[Matej]

You are right. Also description "reusable aerospace vehicle" is not much help.

Hi,


Here is the Tupolev Tu-2000 VKS projects,but what is that strange version
in picture 3,4 & 5 ?.

I don't know what version is it, but for sure is equipped with three different engines:


1) Liquid rocket engines
2) Air breathing jet engines (which retractable air intakes sporting from top of the spacecraft)
3) One single retractable scramjet engine (which sporting from the bottom of the spacecraft)


Instead to have the long time dreamed by the Americans three-cycle engine, Russians decided to divide the problem in three different "segments".

Here is another pic of the TU-674.

Where did you get this "Tu-674" index from?

Where did you get this "Tu-674" index from?

It's written on the side of the nose in the image, while the rear says "Apogei" (Apogee). It's a strange out-of-sequence designation indeed.

Model TU-2000
The answer to the developing United States transatmosfernogo X-30 (NASP) have resolutions of the Government of the USSR dated 27 January and July 19, 1986 on the establishment of equivalent. on September 1, the Ministry of Defence issued a technical specification for odnostupencheskij reusable aerospace plane (IMCC). IMCC was to provide efficient and economical delivery of near-Earth orbit; to ensure high-speed transatmosfernuju intercontinental transport and the decision of the military tasks both in the atmosphere and in outer space. OKB Tupolev, presented Yakovlev and the NGO "energy" projects received the endorsement of the TU-2000.

Tu-2000a was supposed to become a pilot, to test new technologies. When a take-off weight 70-90 t he had developing b speed up to m = 6 at an altitude of 30 km. Before work was stopped in 1992, were manufactured: caisson wings of nickel alloy fuselage elements, the cryogenic fuel tanks and composite fuel lines. Tu-2000 was to use turboprjamotochnye variable cycle engines that use methane or liquid hydrogen.

The second phase was supposed to create variations of space bomber TU-2000b and IMCC or Hypersonic passenger aircraft. Tu-2000b was designed as a single bomber 10.000 km range and takeoff weight 350 tons. Six engines powered by liquid hydrogen were to ensure speed of m = 6 at an altitude of 30 km.

Tu-2000 Variant IMCC would have a starting weight of 260 tons, altitude over 60 km and speed of up to 15 m = m = 25 (orbital velocity). 8-10 tons of payload can be displayed on a 200 km orbit. 8 turboprjamotochnyh engines supplemented by Hypersonic Jet air-jet engine (SCRAMJET) and ROCKET ENGINES. For the implementation of the project requires the creation of wide RAMJET and the technology of production and storage aboard LA pereohlazhdennogo (shugoobraznogo) of hydrogen.
Design
The plane made a "tailless aircraft" with Delta-winged. Engines installed in no gondola (HRE) and the rear fuselage (TURBOJET and ROCKET ENGINES).
The layout of the TU-2000 was shown at the exhibition "Mosaeroshow ' 92-' Sukhoi on the stand. A. N. Tupolev. To date, all the activities on the project almost frozen due to lack of government funding.

IMCC? Length is 70.6m.

What is this?
Top is Tu-2000A-2?
Bottom is Tu-2000b?

Hi!
http://alternathistory.com/tupolev-giperzvukovye-vozdushno-kosmicheskie-samolety?mini=calendar%2F2017-05
"In 1968-1971, A.n. Tupolev DESIGN BUREAU in the study had several technical proposals for VCS(space aitcraft) with horizontal launch and landing. Take-off weight of the aircraft, according to proposed projects reached 300 and tons more. As the powerplant, it was suggested that the ROCKET fuel elements using YARD, as a working body-the hydrogen. Considered variants of multi-stage withdrawal of payloads with VCS, in orbit around the Earth on interplanetary orbits using ionic and plasma mid-flight engines.

At that time the focus of OKB concentrated on PCA-1 and multi-modal thee elyh combat aircraft, and because the deployment of large-scale and costly research works on single-stage VCS was neither the means nor the necessary free scientific and technical human resources. In addition to the first successes in the American space shuttle program, "the military showed no particular interest in projects of domestic VCS, betting in defence space programmes on traditional rocket-space systems, so all these original OKB proposals did not come from the embryonic State.

To illustrate the works of that period, we can cite materials on the project VCS with a nuclear rocket engine (YARD).

Started by VKS with YARD began in OKB, together with a number of enterprises and organizations of industry in 1966 as the main powerplant was gazofaznyj nuclear rocket engine, which was supposed to have the following main features affecting the layout of the VCS:

-working body with low specific gravity-liquid hydrogen;
-high specific impulse;
-large thrust (up to 600 CU);
-tight restrictions on lateral strain;
-inadmissibility of deep throttling YARD;
-radioactivity of missile Jet;
-presence on board high power nuclear reactor, which simultaneously with useful work on heat propellant was the strongest source of radiation."

Model of the Tupolev Tu-2000 hypersonic aircraft, proposed by the Tupolev design bureau. This spaceplane design was intended to have been built in two versions powered by turboramjets and rockets. One was a long-range bomber, flying up to 10,000km at speeds of up to Mach 6 at an altitude of 30,000 metres. The other was an orbital spaceplane capable of delivering payloads of up to 10 tonnes into low-Earth orbit. Originally designed for the Soviet Union, development then continued for use by the Russian Air Force until it was eventually cancelled in 1992. Photographed in Russia.
