You can bl00dy well see a shuttle perched on top of that plane!!
I like your declaratives..
"no you are wrong"..
well at least tell me why you think Im wrong..
On one side I'm trying to defend you chinese from all these american copying accusations.. and Im getting it from you all as well!!??!!
Very pathetic... maybe you deserve to be accused of copying because I only see a very strong retort when non-americans bring up the copying claim on
All american posters' anti-chinese taunts on the subjects strangely go unanswered or are replied at most with a feeble cry!!
Is it because most of you chinese on this site are living in america, and fear a reprisal of sorts if anything anti-american is said??
weird.. really weird..
I'm not standing up for you guys any more..
the space shuttle could be this
Class: Manned. Type: Spaceplane. Nation: China.
The first model of the planned 921-3 manned shuttle was exhibited at Hannover Expo 2000. This showed a double-delta winged spaceplane with a single
vertical stabiliser, equipped with three high-expansion engines. Based on the size of the presumed two crew side-by-side cockpit, dimensions could be
very roughly estimated as a wingspan of 8 m and a length of 12 m, and a total mass of 12 tonnes. This seemed about half the size but the same
configuration as the six-engined orbiter designed in the mid-1990's.
The Chinese 921-3 shuttle concept was a two-stage system with horizontal takeoff and landing. The appearance and layout of the system was similar to
the West German Saenger-II. Launch mass would be 330 tonnes. An aerospace plane with accommodation for two to three crew and a payload of 6 tonnes
would be mounted atop the first stage. It was felt by the Chinese that the horizontal launch method would result in lower system weight and provide a
more flexible system that could be operated from any airfield.
The hypersonic lifting body first stage would be 85 m long and 12 m in diameter with three vertical stabilisers. The stage would have a launch mass of
198 tonnes and a landing mass of 79 tonnes. At launch the stage would be powered by six Lox/LH2/Methane engines with a thrust of 40 tonnes each and a
specific impulse of 370 seconds. These would be supplemented by eight LH2-powered direct-flow ramjet engines with a specific impulse of 3500 seconds.
The rocket engines alone would power the vehicle from the runway to a speed of Mach 0.8, at which point the ramjets would ignite. Up to an altitude of
9 km and a speed of Mach 1.8 to 2.0 the rocket and ramjet engines would operate in parallel to provide a constant acceleration, the rocket engines
throttling back as the ramjets increased in thrust. Thereafter the first stage would be powered by ramjet thrust alone until it released the orbiter
at an unspecified hypersonic speed. It would then return to its launch base.
The orbiter would have a launch mass of 132 tonnes, a landing mass of 25.3 tonnes, and would be equipped with four Lox/LH2 engines with a specific
impulse of 460 seconds and thrust of 21 tonnes each. These would take the stage to an elliptical orbit of 100 to 300 km altitude. Further engine
manoeuvres could take the spacecraft up to a 500 km altitude orbit.
China published photographs of a two-seat spaceplane simulator as early as 1980. This was possibly a test cockpit in an aircraft that flew parabolic
trajectories to provide brief periods of zero-G. Given Tsien Hsue-shen’s, lifelong interest in winged hypersonics, it seems likely that this two
seater was indeed the cockpit for a Chinese Dynasoar-type spaceplane. Reports of the existence of a wind tunnel model have continued through the
years. However lack of funds prevented full scale development from beginning.
In April 1992 the Chinese leadership decided that an independent manned space program could now be afforded. The Chinese National Manned Space Program
was given the designation Project 921. The third stage, 921-3, was a modern space-earth transportation system, using a delta winged orbiter, to be
operational by 2020. The 921-1 manned capsule entered full scale development in 1993 and the 921-2 space station in 1999. Only preliminary work has
been undertaken to date on the 921-3.
Some photographs have been released of a wind tunnel model. The narrow fuselage and wing tip vertical stabilisers were strongly reminiscent of the
United States’ X-20 Dynasoar spaceplane of the 1960’s. Another picture shows computer simulations of airflow around a different double-delta
winged spacecraft. This has an appearance very close to the US space shuttle, but without a tail. This more closely resembled the Hannover model,
except the latter was equipped with a modest vertical stabiliser similar to that on the Russian BOR-4 spaceplane.
This very ambitious project will probably be realised in a different form than that originally planned some time in the first half of the next
century. The Hannover model suggests that a modest spaceplane, launched by expendable boosters, would be flown before proceeding to any full-scale
reusable winged launch vehicles. By 2002 Chinese space scientists were speaking of a two-stage to orbit, ballistic recoverable transport as the first
recoverable Chinese space vehicle.
Crew Size: 2. Length: 12.00 m. Maximum Diameter: 2.00 m. Span: 8.00 m. Mass: 12,000 kg.
LOL i live austraila and trust me no one in the melbourne area likes americans
very anti-bush anti-american
