Abstract:

A monopropellant hydrazine propulsion system for satellite, which has been successfully used to launch the China geostationary communication satellite, is presented. The propulsion system is long-life and high-reliability one. The preformance of this system and its components, the characteristic of critical components and reliability test, the compatibility test of materials, the control of microparticles and whole system firing test are also discussed. The reliability calculationhas been carried out based on the data in flight and ground tests.
