Abstract :
The in-house developed NASA Lewis Research Center thermal/structural/RF analysis program was designed to accurately simulate the ACTS in-orbit thermal environment and predict the RF antenna performance. The program combines well-established computer programs (TRASYS, SINDA, and NASTRAN) with a dual-reflector-physical-optics RF analysis program. The ACTS multibeam antenna configuration is analyzed, and several thermal cases are presented and compared with measurements (preflight). The overall simulation results were in agreement with the measurements. The thermal/structure/RF analysis program could provide an indirect means of verifying in-orbit antenna performance.<>
