概述了国内外满足航天员安全的不同逃逸系统方案及特点,从逃逸发动机配置、逃逸飞行器规模、运载能力等方面综合分析了逃逸塔、逃逸级、自逃逸模式对运载火箭的影响,综合对比后认为逃逸塔方案优于逃逸级方案,建议优选方案为无整流罩状态的逃逸塔方案,将液体逃逸级方案作为备选方案.%Various escape schemes in the world that could satisfy the astronaut safety requirements were reviewed. The effects of the escape tower, escape stage and self-escape mode on the manned launch vehicle ( MLV) were studied and analyzed from the aspect of escape engine configuration, escape aircraft scale and launch capability. After comprehensive analysis,it was found that the es-cape tower scheme had more advantages than that of the escape stage. Thus, it is recommended that the escape tower scheme ( without fairing ) is the optimal scheme, and the liquid escape stage scheme is the backup.
