Space heat flux simulation and programmable load for thermal test of space optical remote sensor
摘要
Abstract
The whole process of space heat flux analysis, heat flux simulation and programmable load for ther-mal test is expatiated for a given space optical remote sensor working in sun-synchronous orbit.Firstly, space heat flux simulation process of space optical remote sensor is summarized.Secondly, calculation methods of solar radiation, earth albedo and earth infrared radiation are introduced.Thirdly, the space total absorbed heat flux for the given space optical remote sensor is calculated, and the average heat flux of the sunlit area and the shaded area is gained.Finally, the space heat flux simulation method and tactic of thermal test are confirmed, and open-loop control program of programmable power is written using LabVIEW language , and space transient heat loads of thermal test are accurately applied.The results of test indicate that the deviations of applied heat load are within ±2.5%, and the deviations which can meet the requirements of thermal test.关键词
