摘要
Abstract
The technology characteristics and development trend of liquid apogee engines for satellites at home and abroad are summarized in this paper.The performance specification and the application of the typical engines abroad and the 490 N engines of three generations made in China are introduced.Since 1990s,the performance of the injectors in liquid apogee engines for satellites has been increasingly improved,and all the thrusters have adopted new type high-temperature oxidation resistant materials such as iridium/rhenium and C/SiC composite materials.Benefiting from the modified injectors and new materials,the performance of the liquid apogee engine has been significantly improved,and its specific impulse is up to 323 s.关键词
