摘要
飞机发动机单喷嘴测试中,喷嘴喷射角度、中心角及流量不均匀度的测试是其主要的测试项目。针对以上测试项目及相应测试要求给出试验器的液压控制系统原理图,提出适用于特定工作环境的液压控制元件及小流量检测方法,描述大范围压力闭环控制的具体工作方式。试验结果表明,该试验器能满足喷嘴测试的具体要求。
During aircraft engineer single nozzle testing,the right nozzle spray angle,center angle and flow un-uniformity test are the main test items.The hydraulic system control schematic diagram of the tester was given in response to above test requirements and items.The hydraulic control components and small flow detection method applicable in a particular work environment were presented.The pressure of large-scale closed-loop control of specific work was described.The results show that the test can satisfy the specific requirements of the nozzle test.
