Aiming at the problem of performance degradation caused by the long-time running of the aero-engine rear variable area bypass injector, the fatigue strength of the components will be degraded under the action of load, and the degradation of the performance of these components will lead to the degradation of the performance of the mechanism, failing in the adjustment accuracy to meet the design requirements. The degradation will also lead to the failure of the mechanism to meet the speed regulation, resulting in the degradation of the engine's variable cycle, which in turn affects the overall performance of the aircraft flight.
