The invention discloses a manned spacecraft cabin pressure protection system, and belongs to the field of spacecraft environment control and life support. According to the system, cabin re-pressing and space suit combined pressure protection is adopted, and when a spacecraft encounters pressure emergency conditions such as cabin gas leakage and the like, the life safety of astronauts is guaranteedunder the pressure protection of space suits; and when the astronaut is engaged in cabin activities such as feeding, excretion and the like, the astronaut needs to take off the space suit and is exposed to the cabin environment, the system completes cabin re-pressing before the astronaut acts and maintains cabin pressure in the activity stage to guarantee the life safety, and the pressure protection system is periodically switched among the three modes of a space suit mode, a cabin re-pressing mode and a cabin pressure maintaining mode. Life safety guarantee and physiological activity requirements of the astronauts under the cabin pressure emergency condition are met, and long-time pressure protection is provided for the astronauts through combined pressure protection of cabin re-pressingand the space suit.

    本发明公开一种载人航天器座舱压力防护系统,属于航天器环境控制与生命保障领域。该系统采用座舱复压与航天服的组合压力防护,在航天器遇到座舱气体泄漏等压力应急状况时,航天员在航天服的压力防护下保障生命安全;航天员从事进食、排泄等舱内活动时,需要脱去航天服并暴露于座舱环境,系统在航天员活动前完成座舱复压并在活动阶段维持舱压以保障生命安全,压力防护系统在航天服模式、座舱复压模式与舱压维持模式这三种模式间周期性切换。本发明实现了座舱压力应急状况下航天员的生命安全保障以及生理活动需求的满足,通过座舱复压与航天服的组合压力防护,为航天员提供长时间的压力防护。
