摘要： 着陆缓冲技术在航天器回收系统中的应用日益广泛,文章对着陆缓冲过程所使用的两种发动机推力制度进行了比较;分析了着陆缓冲过程中影响系统最终性能的因素。认为影响最大的因素是初始条件和环境条件的改变,对此提出了一种较为实用的控制方法。应用这一方法,可以最大限度地消除初始条件和环境条件的改变对着陆缓冲装置性能的影响。

Abstract: The impact attenuation technology is more and more widelyused in recovery system of spacecraft.The two kinds of retrorocketthrust mode applied in impact attenuation process are compared in thispaper,and the factors are analysed which influence the final perfor-mances of the system in impact attenuating process.The changes of systeminitial and environment conditions are regarded as the maximum inf-luence factor,so a pragmatic control method is put forward to solve thisproblem.By applying this method the influence of the changes of theinitial and environment conditions on the performances of impact attenu-ation device can be eliminated ultimately.
