Matej said:Tupolev Tu-2000 derived SST
flateric said:Mato - nice to see you. I'm not sure if that Tupolev HST is really Tu-2000 derived. This model as shown at LeBourget in 1987 and became a subject of close interest of GD/FW guys who tried to make another study based on model photographs.
At the 1987 and 1989 Paris Air Shows, Soviet Aviation officials indicated that a civil hypersonic transport would undergo development in the near future. According to these officials, the Tupolev Design Bureau - which, according to Central Aerohydrodynamics Institute (TsAGI) Director German Zagaynov, conducts "extensive" work in hypersonics - will design the six-engine, Mach 5 to Mach 6, 300-passenger aircraft that would fly from Moscow to Tokyo (about 7,250 km) in about two hours. Central Scientific Research Institute of Aviation Motor Building (TsIAM) Deputy Director Vladimir Sosunov has stated that the proposed airliner "could" use turboramjets. The airliner - about 100 meters in lengthand 4 meters in fuselage diameter - reportedly will use a cryogenic fuel, likely to be liquid methane, for the propulsion system and to actively cool aircraft structures and subsystems. A.A. Systsov, Soviet Minister of the Aviation Industry, stated in 1987that the aircraft would be created in the next 15 to 20 years.
