为了解决高压强固体发动机压强测试过程中压力传感器损毁率高、压力测试数据失真的问题,提出了一种测试缓冲结构设计方法。通过合理设计弯管的弯曲角度、曲率半径等参数,强制气流转弯以削弱高温高压气流冲击波能量,从而在保护压力传感器的同时有效测量工作压强。结果表明,该压强测试缓冲结构可解决高压强测压时压力传感器损坏和测试精度问题。

One kind of impacting damper design method has been proposed to solve the problem of high pressure sensor damage rate and pressure testing data distortion in the process of high pressure motor pressure test. Through reasonable designing of parameters such as bend pipe bending Angle and radius of curvature, the high temperature and high pressure airflow has been forced to turn to weaken the shock wave energy, accordingly pressure sensor can be protected and the pressure can be effectively measured. The results show that, the problem of pressure sensor damage can be solved and the test precision can be ensured by this pressure test method.
