  • Mass injecting pre-compressor cooling (MIPCC) can change the co-working line of areo-engine,and then influence the operating characteristic of engine.The influence regulation of MIPCC on control plan was grasped by analyzing the effect of the MIPCC on the dual-rotor turbofan engine parts and whole aero-engine,especially on the slip between high and low rotors,and on this basis,through perfecting related control plan and verifying the effectiveness of the control plan by the experiment.Results showed that,the control static error of engine low pressure rotor speed reduced from 2.6% to 0.49%,and the step of low pressure rotor speed from throttle state to intermediate state reduced from 4.92% to 1.46%,therefore the performance and experiment security of the engine was achieved.
