产品描述
Aerodynamic Noise
Several sets of test devices including microphone, 160-channel PXIe high speed acquisition system, sound source and etc. are equipped, microphone array design method is mastered, two sets of microphone array (63 channel and 110-channel, respectively) are developed, and all test devices required by the whole procedure of acoustic wind tunnel test from calibration to acquisition and then to process are available.
Deep research and wind tunnel test validation are carried out for several test technologies like aerodynamic noise source positioning method, wind tunnel test shear layer correction method, background noise influence elimination method, mobile noise source positioning technology and so on.
