在常规循环双轴分排大涵道比涡扇发动机模型基础上,通过引入间冷器、回热器和间冷涵道模型,发展了间冷回热航空发动机(IRA)性能模拟方法.编写了相应的性能计算程序,计算并分析了一种间冷涵道独立排气的IRA的高度速度特性和节流特性.计算表明:全包线内,回热器一直可以正常换热,IRA可以正常工作.不同工况下,IRA的净推力都接近或大于对照常规循环涡扇发动机,而耗油率较对照常规循环涡扇发动机降低9%~20%.
Based on the conventional two-axial high-bypass ratio turbofan engine model, a simulation method of intercooled regenerative aero-engine (IRA) performance was developed by introducing intercoolers, regenerator and intercoolers. The corresponding performance calculation program was used to calculate and analyze the high velocity and throttling characteristics of an IRA with independent exhaust of intercooled ducts.The calculation shows that the regenerator can be normally heat- Normal operation.Under different operating conditions, the net thrust of the IRA is close to or greater than that of the conventional circulating turbofan engine, while the fuel consumption rate is 9% -20% lower than that of the conventional circulating turbofan engine.
