Research on Aeroengine Intake Air Distortion Test System
The intake distortion test of aeroengines is of great significance for their stability.In order to meet the needs of the aeroengine intake aberration generator test system,a test system design method based on 3D print-ing technology and high-speed multi-channel data acquisition is proposed,which improves the efficiency of the system design and completes the high-speed real-time acquisition of data under the premise of ensuring the ac-curacy of the data.On this basis,the data are processed using spatio-temporal filtering and fluid flow recon-struction,and the test system interface is designed based on MATLAB.Finally,the calibration test of the pres-sure measurement rake and the wind tunnel test of three kinds of distortion maps are carried out respectively,and the test results show that the total pressure value of the test channel and the wind tunnel outlet is less than 0.2 kPa,and the error between the test distortion index and the target distortion index of the distortion maps is less than 1.2％,the validity and accuracy of the adopted data processing algorithm and test system are veri-fied.
