F119发动机总体性能特点分析与评估

Analysis and Evaluation of F119 Engine Overall Performance

根据航空发动机总体性能设计的一般规律,对不同的资料数据进行筛选,初步选定了F119发动机相对准确的总体及部件性能参数,并以此为参照基准进行了F119发动机设计点、起飞点和超声速巡航点的总体性能计算,评估了F119发动机在这三个典型状态点的性能,概要地梳理了F119发动机的总体性能设计理念。

According to the principles of overall performance design for aero-engine, the relatively accurate overall and component performance parameters of F119 are chosen initially. By using these parameters as the basic reference, the overall performance parameters at the design point, the take-off point and the supersonic cruise point are calculated and the performance of F119 engine at the three typical point is also evaluated. The concept and ideas of overall performance design for F119 engine are summarized briefly.
