Abstract:A high pressure turbine rotor dynamic stress test method of “telemetry+long span lead wire pipe” was designed for the dual-rotor turbofan aero-engine in the whole engine state. Combined with the simulation design of telemetry cooling amid the dual rotor and customized high temperature strain gauge, the dynamic stress test of the high pressure turbine rotor of the dual-rotor turbofan aero-engine was completed for the first time in China, and the dynamic test data of the high pressure turbine rotor blades in the full speed range and the whole engine state were obtained. The test results showed that the test mechanism and its cooling method designed can effectively solve the problems such as the difficult test signal extraction and poor signal transmission stability of the high pressure turbine rotor in the whole dual-rotor engine, the customized high temperature strain gauge and its installation and protection technology can effectively overcome the harsh installation conditions of the high pressure turbine blades on the whole machine, such as extreme high temperature, airflow erosion and narrow space. The method proposed can provide an important reference for the relevant test tasks.
