对俄出口GVU-600空间环境模拟器研制

摘要

GVU-600空间环境模拟器是我国首次为俄罗斯研制的一台航天专用设备,它可以模拟真空、冷黑和太阳辐射3项空间基本参数,主要用于进行卫星热平衡、热真空试验.该设备为卧式圆柱结构,容器内径8m,总长13.5 m,容积600m3,极限真空1.4×10-5 Pa,热沉温度-190℃.文章主要对该设备的技术指标、系统组成及功能进行了介绍,并给出了研制结果.%The space environment simulator is used to simulate the vacuum, the cold and black and the solar irradiation.GVU-600 is the first aerospace facility developed by China for Russia.It is mainly used for the thermal vacuum test and the thermal balance test.GVU-600 is horizontal and cylindrical with a dimension of 8 m(inner diameter)×13.5 m(total length), an ultimate pressure of 1.4×10-5 Pa, and an average temperature of -190 ℃ in the thermal shroud.This paper discusses the facility's specifications, configuration, and functions, with test results.
