The Application of IRAs Optimizing Design in Vacuum Thermal Test


Article Preview

The thermal vacuum environment simulation test is indispensible for the development of spacecrafts. And the simulation of the external heat flux exerted onto the spacecraft is one of the determining elements of the simulation test. In China, the infra-red simulation is a common method that used as simulation equipment of the external heat flux. The planar infra-red arrays is the most typical structure elements for planar spacecraft surface, but the margin effect of infra-red arrays influences the flux uniformity on heated surface severely. Based on Monte Carlo theory, some optimizing design guidelines had been drawn about planar infra-red arrays in past investigation. This paper introduces some testing and experiment that could confirm these guidelines, and these guidelines had been applied in some vacuum thermal tests of spacecrafts successfully.
