摘要
Abstract
Space large rotating payloads,being complex in structure and constantly rotating,are a challenge to the test validation of their thermal characteristics.A case study of the thermal balance test method of the microwave scatterometer in Haiyang-2 satellite is presented.A direct validation method is used in the engineering model phases,which can used to forecast the in-orbit temperature directly from the ground test result.Meanwhile,an indirect validation method is used in the flight-model phases,which may used to predict the in-orbit temperature through the thermal analytical model.A comparison between the thermal test results,the thermal analytical results and the flight results shows the correctness and the effectiveness of the thermal balance test.关键词
