新一代载人飞船逃逸系统设计与关键技术研究

Research on Design and Key Technologies of Launch Abort System for China’s Next-generation Manned Spacecraft

新一代载人飞船发射逃逸系统用于航天员进舱直至入轨船箭分离期间发生紧急故障将航天员带离危险区域。面向载人月球探测和近地空间站任务,采用MBSE方法系统分析了新飞船发射逃逸系统任务需求和特点,研究确定了逃逸模式和逃逸系统设计,对弹道与控制、结构与分离、气动、动力、供电与信息等开展了专项技术研究,识别出逃逸技术难点并提出了解决方法,对关键技术攻关进展进行了总结,并将在后续研制中进行充分的考核验证,确保在正式飞行任务中稳定可靠工作,以进一步提升载人飞行任务的安全性。

The safety of astronauts is of utmost importance in any manned space mission.That’s why the launch abort system(LAS)of China’s next-generation manned spacecraft has been designed with meticulous attention to detail.From entering the cabin to entering the orbit,every step has been analyzed using the MBSE method to ensure the system meets the highest safety standards.This system is specifically aimed at manned lunar exploration and low-Earth-orbit space station missions,making it a crucial component of any manned space program.The launch abort mode and system design have been studied and determined,with special research conducted in various aspects such as trajectory and control,structure and separation,aerodynamics,power,and information.The identified technical difficulties have been overcome with proposed solutions,and the development of key technologies has been summarized.LAS will undergo full assessment and verification in subsequent development to ensure stable and reliable operation during formal flight missions.With this new launch abort system,the safety of manned spaceflight missions can be further enhanced and improved.
