Abstract: Inlet/engine compatibility is very important for developing a new aircraft.A usual way of compatibility test is to measure the inet instantaneous pressure distortions and find the peak value, and then to compare it with the allowable value of engine.In this paper, the editing and data analysis system for inlet dynamic pressure distortion is depicted.By increasing data sampling frequency, the described method might be useful in inlet/engine compatibility test.
