Analysis on Distortion Preventing Measures in Engine Flow Channel of Carrier-based Aircraft
The interaction between engine thermal wake and carrier deck wind can generate complex airflow fields during take-off and landing of carrier based aircraft,that has a significant impact on the stability and reliability of aircraft engines.Reducing the distortion of the inlet flow field of carrier based aircraft,ensuring the matching of carrier based aircraft inlet and engine,and improving the safety and reliability of aero engines are important evaluation indicator for the compatibility between the carrier and the aircraft.The article introduces the wake field conditions around the deflector and the tail nozzle of the aero engine on the aircraft carrier,analyzes the causes of the engine exhaust in-halation into the inlet of the carrier-based aircraft.It describes the working conditions of the carrier-based aircraft after inhaling the engine exhaust,and proposes specific measures to prevent the flow channel distortion of the carrier-based aircraft aero engine on the carrier.It is of certain significance for improving the working conditions of the aero engine on the carrier and preventing the surge of the aero engine.It also has certain reference value for the use of domestic aero engines on the carrier.
