Thanks for posting those, borovik. Now if one could get hold of this issue... Also you said "initiated a historical review", does this mean there will be a second part?

Another image of the OOS was posted by flateric here: http://www.secretprojects.co.uk/forum/index.php/topic,28.msg1125.html#msg1125. Perhaps it could be moved to this thread?

And Triton, the description you posted has been directly lifted from http://www.astronautix.com/craft/tu2000.htm.

That's not Tu-2000, its a TsAGI Mach 5 passenger aircraft model presented at the 1989 Paris Air Show. There should be a color image of the model along with additional information somewhere on this forum, but guess if I can find it now  :(

Here's an image of the real Tupolev hypersonic passenger airplane study. From "Aviation and Cosmonautics" 1/2010. Unfortunately there doesn't seem to be more information available.

Most accounts of the Soviet 1980s VKS program state that

Quote
It is known that the Tupolev, Yakovlev, and Energia design bureaus submitted designs. No details of the Yakovlev design have become available to date.

It seems that this information has been copied everywhere from Encyclopedia Astronautica (http://www.astronautix.com/craft/yakvmvks.htm), which in turn gives the Piotr Butowski article "Black Reds" in Air Forces Monthly X-Planes Special, February 1998, p. 35 as the original source. What I find interesting that no Russian sources seem to mention a Yakovlev proposal, either independently or when discussing the Tu-2000 or the NPO Energia VKS. Actually I don't remember seeing mentions of any Yakovlev hypersonic work in general. Does anyone have any comments on this?

It's also interesting to note that much of the information on late Soviet "secret projects" such as the Mikoyan 301, 701 and Tu-360 seems to originate from that same Piotr Butowski article.

The VKS accepted the requirement for an tail-less aerodynamic configuration consisting of four turbojet engines including the main booster being located under the rear fuselage. Another prototype consisted of a liquid-propellant engine for manoeuvring in space and placed between the turbojet engines. The design resulted in a delta wing with a relatively small area and low aspect ratio overall. The bulk of the lift was to be created by the fuselage by compression lift. As such, this aerodynamic configuration would have made it efficient for high-speed hypersonic travel but would have complicated low-speed operations and landing. Controls of the Tu-2000A/B was to be made by small elevons on the wing and a simple rudder on the tail fin. The base engine was to house an adjustable oblique-cut combustion chamber and with multiple-fuel supply systems.

The fuselage-bow of the Tu-2000 was house the cockpit with a seating for two and with the remainder housing fuel tanks containing liquid hydrogen. The nose-piece contained a detachable cab/lid  which was to house a detachable parachute for escape from the cockpit.  The cockpit itself was to contain a separate electronic-equipment compartment to which the nose landing gear also retracted. For the supply of the liquid propellant oxidizer, there was to be an oxygen tank rear fuselage and this single tank system was to be used by all engines. It was thought that such an aircraft would be able to deliver a payload of 6-10 tonnes into orbits of 200-400 km.

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

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

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".
