航空发动机总体方案论证耦合模型研究

Research on Coupling Model of the Aero Engine General Scheme Argumentation

方案论证是航空发动机设计流程中的重要环节,本文提出了一种航空发动机总体方案论证耦合模型。该耦合模型可以对发动机压比、压气机流路、压气机效率、涡轮效率、涡轮前温度和涡轮冷气量进行快速评估,并给出调整建议。加速发动机方案论证的进程,缩短航空发动机设计周期。

Scheme argumentation is the main step of the aero engine design, and coupling model of the aero engine general scheme argumentation is proposed. Pressure ratio, compressor streamline, compressor efficiency, turbine efficiency, turbine inlet temperature and turbine air cooling mass are evaluated quickly, the adjustment is given. This method can accelerate the process of aero engine general scheme argumentation, and shorten the time of aero engine design.
