随着深空探测任务的发展,载人飞船规模不断加大,返回舱再入返回的质量越来越大,主要依靠降落伞方式减速的难度也随之增大。分析国外在研载人飞船研制特点,特别是国外载人飞船配置反推发动机的可行性,提出利用反推发动机实现制动着陆的方案设想,重点是反推发动机点火高度、反推前返回舱下落姿态,以及反推发动机安装位置等对发动机推力、工作时间等参数分析。
With the development of deep space exploration missions, the manned spacecraft is constantly expanding in size and the quality of the return capsule entering and returning is increasing. The difficulty of decelerating mainly by parachutes also increases. This paper analyzes the feasibility of developing a manned spacecraft abroad, especially the feasibility of a foreign manned spacecraft equipped with a thrust reverser engine, and proposes a scheme of using the thrust reverser engine to achieve braking landing. The key point is to reverse the engine ignition altitude, Drop posture, as well as the location of the thrust reverser engine installation on the engine thrust, working time and other parameters analysis.
