飞机上耐高液(气)压部附件易发生泄漏破损等问题,对飞机的安全运行至关重要。本文开发了一种测试系统,以气体和液体为介质,以飞机蓄压器为例,通过压力检查、泄露测试、摩擦阻力测试,检测待测部件是否合格。检测结果证明,该测试系统可作为飞机机械系统耐高液(气)压部附件检测的一种参考方法。 Aircraft high-pressure (gas) pressure attachment prone to leakage damage and other issues, the safe operation of the aircraft is essential. In this paper, a test system has been developed, which uses gas and liquid as the medium and aircraft pressure accumulator as an example. Through pressure check, leak test and frictional resistance test, the tested components are tested. The test results show that the test system can be used as a reference method for testing the attachment of high pressure resistant (air) pressure parts of aircraft mechanical systems.
