Selection Method of Sensor Locations of Aero Engine under Aerodynamic Load
This paper presents a method for selecting sensor measuring points of aeroengine under aerodynamic load.Based on the finite element model of the test rig of a single rotor system of similar design,the aerodynamic load characterization model was established.A response calculation method was proposed to calculate the sensitivity of the response to aerodynamic load according to the surface response of the casing.Based on the results of sensitivity analysis,the effective independence method was used to analyze the independence of measuring points on the casing surface.Combined with the sensitivity and independence,the optimal sensor location was selected,and the response of the control group was compared.The results show that the response of the optimal location is at least 8 times higher than that of the control group,which verifies the effectiveness of the method.
