Abstract:
Based on the test-port form of high-pressure pipeline for Shenzhou spacecraft propulsion system, the theoretical formula of tightening torque for the sealing-plug was obtained. According to the results of theoretical calculation and finite element simulation analysis, the quantitative tightening torque of the high-pressure sealing-plug of spacecraft is recommended as [T]=(24±5)N·m combined with the empirical checking torque.. The recommended tightening torque value has been applied to the Shen-zhou-11 spacecraft and has passed the flight assessment of spacecraft.
