摘要

摘要: 针对航空发动机部件蜕化导致性能变差问题,设计了航空发动机性能恢复控制系统,系统根据发动机的工作状态以及健康状态在常规转速控制模式、稳态性能恢复控制模式和加速性能恢复控制模式之间切换.稳态性能恢复控制模式在常规转速控制模式的基础上设计了一个外环控制回路,通过自适应修正稳定状态下压气机转速指令达到蜕化发动机性能恢复的目的;加速性能恢复控制模式通过综合常规转速控制方法和喘振裕度控制方法,在保证发动机气动稳定的同时,充分挖掘发动机潜力,从而达到恢复蜕化发动机加速性能的目的.通过不同状态不同部件蜕化下的仿真结果表明恢复蜕化发动机性能的有效性.

Abstract: The performance recovery control system of an aircraft engine was designed for deterioration compensation due to aging.The system switched among the conventional speed control mode,steady state performance recovery control mode and acceleration performance recovery control modes,based on the engine operation condition and healthy condition.Steady-state performance recovery control mode is an outer control loop added on the conventional speed control mode to recover the deteriorated engine performance through adaptive adjust engine compressor speed command at steady state.Acceleration of recovery control modes ensures the air stability of the engine and fully taps the potential of the engine by integrating conventional speed control and surge margin control.Simulation results of different states under different components deterioratation show the validity of the proposed system.
