Shenzhou V carrier rocket adopts 55 new technologies
( 2003-10-15 11:34) (Xinhua)
The "Long-March" CZ-2F carrier rocket that
launched manned Shenzhou-5 spacecraft has adopted 55 new technologies, including
fault detection and treatment and escape systems, said a Chinese rocket expert.
Huang Chunping, commander-in-chief of the rocket system of China's manned
spaceflight program, said that the fault detection system would automatically
detect and diagnose any fault in the initial stage of the flight and inform the
escape system, which would, in turn, separate the spaceship from the rocket to
ensure the safety of the astronaut.
He said that for the first time the rocket is assembled and tested and the
combination of the spaceship, rocket and platform is transported in the vertical
position.
To improve the reliability of the launch, dual guidance and stability control
systems have been adopted on the "Long-March" CZ-2F carrier rocket, said Sun
Ningsheng, deputy chief designer of the rocket system.
Development of "Long-March" CZ-2F carrier rocket, intended mainly for
spaceship launch, began in 1992. It is the most sophisticated and most reliable
type of carrier rocket developed in China.
