| Abstract: | In the vacuum thermal test for spacecraft with sealed cabin, the pressure in the cabin should be under control and adjustment. A pressure control system(PCS) is designed for this purpose, with functions such as depressurization, repressurization and keeping the pressure unchanged. The structure, principle and design method of the PCS are discussed. The simulation results indicate that the PCS can satisfy most requirements of the vacuum thermal test. |
