摘要: 射流预冷(MIPCC)会导致发动机共同工作线会发生改变,进而影响发动机的工作特性。通过分析射流预冷对双转子涡扇发动机部件和整机的影响,特别是射流预冷对高低压转子转差的影响,掌握了射流预冷对控制计划的影响特性,在此基础上完善了相关控制计划,并通过试验验证了控制计划的有效性,结果表明:发动机低压转子转速控制静差由2.6%减小为0.49%,节流状态到中间状态低压转子转速阶跃量由4.92%减小为1.46%,实现了发动机的性能及试验安全。Abstract: 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.
