Pressure Surge Reduction for a Cold Gas Attitude Control System using a Novel Valve Design and Charging Procedure

摘要

The present study proposed a solenoid valve with a groove on the upper surface of the lower poppet and a charging procedure to reduce the occurrence of pressure surge. The grooved solenoid valve minimized the impact of the surge pressure, and an increased suction force was not required even under surge conditions. Moreover, this antisurge thruster was successfully operated under a pressure surge condition, as verified through component level tests and system level tests. The charging procedure was a simple method to reduce pressure surge. No additional weight to minimize pressure surge was necessary with the proposed method.
