摘　　要：随着部件间干涉影响加剧、学科间耦合影响加深,在航空发动机零维总体性能仿真过程中引入高维度因素影响、进行变维度仿真具有重要作用和意义。剖析了变维度方法的提出背景,明晰了变维度方法的发展现状,对比分析了实现变维度仿真的不同技术路径,并以进气道、风扇/压气机、尾喷管、核心机/低压系统等为具体对象总结了变维度混合仿真方法的应用成果。结果表明:变维度仿真方法可以有效提升整机系统级性能仿真精度,自主可控的0D至3D程序是实现基础。部分耦合或特性修正方法在精度、耗时、灵活性等方面最具优势。应着重发展新构型发动机(如变循环发动机)、真实工作环境(如吞雨)等影响的变维度性能仿真研究。With the increasing effects of gas turbine components interaction and multidisciplinary coupling,incorporating higher-dimensional factors into zero-dimensional overall performance it is of important role and significance to introduce high-dimensional factors and conduct a variable-dimensional simulation in the zero-dimensional overall performance simulation of aero-engines.The background of variable-dimensional methods is analyzed,the development status of the variable-dimensional method is clarified,and the different technical paths for realizing variable-dimensional simulation are compared and analyzed and the application results of the variable-dimensional hybrid simulation methods are summarized with the inlet,fan/compressor,tail nozzle,and core engine/low-pressure system as specific objects in this paper.The results show that the variable-dimensional simulation method can effectively improve the system-level performance simulation accuracy of the whole machine,for which the autonomous and controllable 0D to 3D program is the basis for implementation.Partial coupling or characteristic correction methods have the most advantages in terms of accuracy,time consumption,flexibility,etc.The research on variable-dimensional performance simulation under the influence of new configuration engines(such as variable cycle engines)and the real working environments(such as rain swallowing)should be focused on.
