The test of inlet/engine compatibility was carried out during aircraft maneuvers with rapidly changing angle-of-attack(AOA)

angle-of-sideslip(AOSS).The same important test data about inlet/engine compatibility by flightting test were acquired.The test data were selected

calculated and analyzed

and at last the relation among rapidly changing aircraft maneuvers

inlet total pressure distortion and the stability of engine

as well as the relation between inlet total pressure distortion and the stability of engine were obtained.It shows that

the stability of engine and inlet total pressure distortion become worse due to rapidly changing aircraft maneuvers.
