大型空间环模试验设备主要用于为卫星、飞船、探月飞行器的整星真空热试验与大尺寸天线真空低温环境下展开试验提供高真空、全吸收的冷黑背景及空间热辐射环境。该系统设计配备了外热流模拟测控系统、无油真空系统、真空罐、中央控制系统、热沉、氮系统等组成部分。本文概要介绍了本空间环模试验设备的主要性能指标、系统组成以及主要参数设计。
Large-scale space ring mode test equipment is mainly used for satellite, spacecraft, lunar exploration moonlight vacuum thermal test and large-size antenna under low-temperature vacuum environment to provide high vacuum test, full absorption of cold black background and space thermal radiation environment. The system is designed with an external heat flow measurement and control system, oil-free vacuum system, vacuum tank, central control system, heat sink, nitrogen system and other components. This article gives an overview of the main performance indicators, system components and the design of the main parameters of the space ring mode test equipment.
