- 摘要:
- 为研究某推进系统气路启动特性，找到造成影响减压阀建压稳定性的原因，获得稳定的减压阀出口压力建压过程，依据系统仿真方法及相关试验，对该推进系统气路启动特性进行了研究。结果表明，减压阀阀后压力稳定性与阀后的管径及阀内的阻尼孔存在关系。
- Abstract:
- In order to find the reason which affects the pressure-establishment stability of the relief valve and obtain the stable pressure-establishment process at outlet of the relief valve, the starting characteristics of a pneumatic system used in some propulsion system were researched by means of system simulation method and relevant tests. The result shows that the pressure stability behind the relief valve depends on the diameter of the pipe behind this valve and damping area inside this valve.
