Experimental Investigation on High Temperature Starting of Carrier Based Aircraft Engine

In order to solve the problem of high temperature starting of the engine for carrier aircraft, a high temperature starting test has been designed and carried out on the high and low temperature starting law testing facilities.All experimental data are normalized, experimental results show that, at high temperature working condition, if disengaging speed of starter increased 10%, engine's starting time is shorten 0.01, engine's starting maximum exhaust temperature is dropped 0.05.If high-pressure compressor varying stator vane angle of engine is opened 2°, the engine's starting maximum exhaust temperature is dropped 0.03.If ignition speed of engine increased 2%, engine's starting time is expanded 0.03, engine's starting maximum exhaust temperature is dropped 0.02, and if maximum output power of starter increased 3kW, engine's starting time is shorten 0.06, engine's starting maximum exhaust temperature is dropped 0.02.The above four methods have all been proved to improve engine starting performance at high temperature working conditions, it is of great significance to optimize high temperature starting performance for carrier based aircraft engines. © 2018, Editorial Department of Journal of Propulsion Technology.
