一种舱内/月面兼用登月航天服总体概念设计

Conceptual design of dual-purpose lunar EVA spacesuit

航天员在月面驻留与活动离不开登月航天服的保护。文章考虑载人登月任务环境对登月航天服的各种特殊要求后,从满足环境适应性的服装工艺设计角度对登月航天服进行了总体概念设计:应用基于模型的系统工程(MBSE)方法,利用SysML搭建登月航天服模型,采取舱内/月面兼用设计模式;主要对其头盔、躯干主体部分、手套、靴子、生命保障背包,以及安全性可靠性等方面分别开展设计与说明。该设计思路和方案可为我国载人登月以及载人深空探测航天服设计提供参考。

The lunar residency and the extra-vehicular activities of astronauts depend very much on the protection of the lunar EVA spacesuit.In view of the special requirements of various constraints on the spacesuit for manned lunar landing missions,the overall conceptual design of the spacesuit for the lunar landing is carried out from the point of the clothing process design to meet the adaptability of the environment.The model based systems engineering(MBSE)method is used to build a lunar EVA spacesuit model by the SysML,with a dual-purpose design philosophy for both in-cabin and on-the-moon use.The detailed conceptual design is described part by part,including the helmet,the main body of clothing,the gloves,the boots,the life support package,as well as the reliability and the security.The related design ideas and schemes may serve as a reference for the EVA spacesuit design for the manned lunar landing or even further planet landings.
