Abstract: The constraints of engine military regime is analized,and a whole range performace optimizing method is given.The engine perfomance at high altitude and high mach number is greatly improved by suitabily choosing high pressure rotor speed matching to the throttle ratio and using the “cold overrunning”and “gas temperature storage utilizing”techniques

Key words: Aircraft aeroengine;Military regime +;Thrust control;Parameter optimization

摘要： 对发动机最大状态进行了约束分析，提出了全范围性能寻优算法。通过改进设计点高压物理转速和节流比的配置，以及“冷超转”和“燃气储备利用”技术的采用，大大提高了发动机高空高速的推力特性。
