AbstractIn the flight test, the matching compatibility of the fighter inlet and the engine is the key to the test flight of the engine performance quality. Especially at high incidence of high attack angle and over stall maneuver, the characteristics of the inlet are very important to the engine. The current traditional test scheme cannot real-time telemeter the inlet distortion signal.This paper aims at the problem by designing an embedded airborne real-time processing unit which can real-time calculate and telemetry of the inlet distortion signal. Then the results are displayed in the ground monitoring station by cloud image mode. So we can evaluate the matching performance of the inlet and engine during aircraft flight, and achieve the aim of prejudging the risk of inlet distortion.
