基于双轴涡扇发动机热力学模型,采用高低压涡轮间补燃的方法,实现了对发动机性能的改善。研究 分析了高低压涡轮间补燃对发动机高度特性、速度特性以及转速特性的影响。计算结果表明采用高低压涡轮间补 燃的热力循环后,发动机的推力明显提高,耗油率基本保持原来的水平或有所降低。
Based on the thermodynamic model of a dual-axis turbofan engine, the engine performance is improved by using the method of inter-combustion between high and low pressure turbines. The effects of interchain combustion between high and low pressure turbines on the height, speed and speed characteristics of the engine are analyzed. The calculation results show that the thrust of the engine is obviously improved and the fuel consumption rate basically maintains the original level or decreases after using the thermodynamic cycle of recuperation between high and low pressure turbines.
