摘要： 舱外航天服采用主被动相结合的热控方式控制内部的温度,但其外形复杂,影响外热流的因素很多,因此舱外航天服热试验存在着与传统航天器热试验完全不同的特点。文章根据舱外航天服热设计的特点,对舱外航天服的地面热试验方法进行了比较分析和研究,论证了采用等效外热流模拟方法,通过进行舱外航天服系统漏热和散热能力的测试来验证热设计方法的合理性及热试验方法的可行性。

Abstract: Active thermal control technologies were used in extravehicular mobility unit(EMU).The configuration of EMU is complicated and there are many influence factors on reaching heat flux.The thermal test for EMU had the different characters with that of traditional space probe.Different simulation methods of EMU thermal test were presented,based on the characteristics of the thermal design.It′s feasible to validate the thermal design by equivalently simulating the space heat flux as the test thermal boundary and measuring the heat leakage of the EMU and heat dissipation ability.
