Aircraft Engine Valve Components Parking Response Time Measurement System

With the development of technology and society, air transportation has become themainstream mode transport of the rapid transportation industry, aviation problems ofAirlines have become the focus we take attention. Aero engine valve assembly is animportant part of aviation safety issues, it affects the aircraft engine performance, but alsoimpacts the aircraft safety.High requirement of the valve components performance to the aero engine, beforeputted into use, valve components should be detected and analyze comprehensively, and aspecial equipment for the detection is required. While a low cost, and could be to measureparameters of the engine valve assembly will be developed, in order to analyze theperformance inspection and the quality of the valve components. Aero engine valveassembly. Parking response time measurement system is a particularly important part ofvalve assembly test bed. It is based on the measured signal to complete high speedsampling, processing, data transmission, to realize a good transmission between themeasured data and test computer. At present, high accuracy and quick detection technologyis an important link to the development of science and technology, and applicate it to thevalve assembly test bed would play an important role in the aero engine valve assemblytest bed technology and aviation safety issues on China.In the test system of aviation engine valve assembly,"Parking" response timemeasurement provide important data for performance test and quality analysis. The systemis based on DSP chip and high response speed and high precision A/D converter,"Parking"response time measuring method, hardware circuit, and the design of configurationsoftware programming of CCS3.3is put forward, and complete the measurement project.For now, the system has realized parking response time measurement, which has thefunction to measure, display and transmission, and the system of parking response time hasbeen put used into test bed of one kind of aero engine, and it has realized goodmeasurement results.
