航天器非地球轨道热环境模拟技术探讨

月球、火星探测器等非地球轨道航天器与地球轨道航天器对热控的要求有很大的不同,为验证热控设计的合理性,必须在地面做好充分的热环境模拟试验.国内绝大部分空间环模设备都是以模拟地球轨道航天器在轨环境为目的建设的,显然不能满足深空探测需要.文章针对航天器非地球轨道深空热环境模拟技术进行探讨.

The simulation technology of the non-earth orbit spacecraft thermal environment in deep space

After the successful launch of Chang'E-1 lunar satellite, more deep space probes of non-earth orbit will be developed. Since the thermal control requirements for deep space probes ( such as lunar probe and Mars probe ) are very different from those for spacecraft in earth orbit, sufficient thermal environmental simulation tests for the probes have to be performed on ground in order to validate rationality of their thermal design. However, most of test facilities in our country are constructed to simulate in-orbit environment of geostationary spacecraft, which could not well meet the requirements of deep space exploration. This paper discusses the simulation technology of the non-earth orbit thermal environment in deep space.
