Abstract: Based on the flight test of a certain type of aircraft inlet, a compound inlet flow field measurement rake integrating total steady pressure and static pressure is developed and installed in the paper, and the flow field data under different flight conditions is obtained. The static pressure distribution characteristics of inlet flow field are analyzed and compared by two static pressure measurement methods, and the rationality of the two static pressure measurement methods is explored. On this basis, the methods of static pressure measurement and flow calculation are studied. The results show that the deviation of flow calculation using the wall static pressure is larger, followed by the direct static pressure calculation of the pitot tube, and the area correction calculation of the measured results of the wall static pressure is better.
