Steady Enhancement Control Technology of Aircraft Turbofan Engine for Surface Takeoff
In order to improve the aerodynamic stability of aircraft turbofan engines for surface takeoff,two methods are proposed to identify engine inlet temperature rise using compressor inlet temperature and total supercharging ratio,and then the adjustable blade angle of the compressor is adjusted to improve the engine stability margin during takeoff.In ad-dition,to improve the intake distortion circumstances,a method is introduced that reducing the afterburner oil gas ratio di-rectly while the main engine state remains unchanged to reduce the exhaust temperature of the engine outlet.The simula-tion results show that the measure are effective and feasible.The above methods and measures can provide reference for carrier-based fighter engine stability control.
