Thermal distortion measurement of TETRUS type thermal test model of large deployable antenna for mobile communications satellite
Abstract
A thermal test model using TETRUS (tetra trigonal prism truss) composed of three equilateral triangular cylindrical trusses was trial produced and evaluated for the effects caused by thermal environments on the mirror surface. The following topics related to the thermal environmental test are described: TETRUS, the thermal environment test model, the analysis on thermal distortion of the TETRUS, the process and the results of the thermal environmental test, the estimate analysis of electric property at the ambient temperature, and a high and a low temperature, the test configuration, the results of mirror surface accuracy measurements, and electric performance estimation analysis.
