摘要： 载人航天中，应急救生分系统是火箭一飞船系统的重要组成部分，以联盟号应急救生系统为例介绍了其组成、工作程序并研究分析了逃逸动力装置──主逃逸发动机和控制发动机的性能参数与逃逸飞行弹道特性之间的相互关系；从逃逸弹道设计技术指标出发来选取动力装置的主要性能参数（推力大小及工作时间）。仿真计算得出了有益的结论。

Abstract: Emergency lifesaving system(ELS) is a major component of rocket-spaceship system in manned spaceflight.By taking the ELS of " Co" for example,it's composition and process program are introduced in this paper, the relationship between the performance data of escaping power unit (main engine and control engine) and the escaping trajectory is also approached in detail by means of numerical simulation.Some good result are obtained in this paper.
