Design and Experimental Study of Small Disturbance LE Probe for Aero-engine
The numerical simulation and calibration test study are carried out for the small disturbance LE probe,which is used to measure the inter-stage performance of aero-engine.The numerical simulation results show that the LE probe which has type B cowling has less impact for the flow field.The calibration test results show that the LE probe which has type B cowling has better total pressure characteristic,the range of insensitive angles are-30 ° to 10 °,the total pressure measurement error absolute value is not greater than 0.1%.And the optimal design scheme of small disturbance LE probe is obtained for one aero-engine,and the LE probe has been used in the whole flow path parameter measurement test.The test results provide important support for the performance verification and modification of the aero-engine.
