【摘要】 为对比探究未来大推力航空混合动力系统与传统航空发动机的优劣,依托某概念型齿轮传动涡扇(Geared turbofan,GTF)发动机,在Matlab/Simulink数字仿真软件中建立基线发动机模型以及氮氧化物NOx排放和噪声预测等性能参数计算模型,并在飞行任务剖面下初步分析了基线GTF发动机的性能状况。飞行任务剖面动态仿真结果表明,所建模型具有较高的准确度和精度,具有一定的省油降噪潜力,为开展大推力并联混合动力系统多能源管理策略研究创造了基础。更多还原

【Abstract】 In order to compare and explore the pros and cons of the future high-thrust aviation hybrid power system and the traditional aero engine, in Matlab/Simulink digital simulation software, a baseline engine model and a calculation model of performance parameters such as nitrogen oxide NOx emissions and noise prediction are established relying on a conceptual geared turbofan(GTF) engine. Performance of the baseline GTF engine are preliminary analyzed under the flight mission profile. The dynamic simulation results of the flight mission profile show that the built model has high accuracy and precision,and has a certain potential for fuel-saving and noise reduction, which creates a foundation for the development of multi-energy management strategies for high-thrust parallel hybrid power systems.更多还原
