采用F100-PW229的参数,对发动机增设级间燃烧室后进行了非理想循环分析,比较了不同马赫数下级间燃烧室与加力燃烧室的性能差异,分析了部件效率对带级间燃烧室发动机性能的影响,对比了主燃烧室、级间燃烧室、加力燃烧室的燃烧效率;计算结果与理想循环存在差异:亚声速下,级间燃烧室发动机推力的增加需要相近增量的耗油率,超声速下同等耗油率可增加约10%推力;其经济性、机动性介于常规发动机和带加力燃烧室发动机之间;最后对增设级间燃烧室的发动机进行了参数优化.
The parameters of F100-PW229 were used to analyze the non-ideal circulation of the engine after the inter-stage combustion chamber was added. The performance differences between the sub-stage and afterburner were compared, Engine performance, the combustion efficiency of the main combustion chamber, the interstage combustion chamber and the afterburner was contrasted. The calculated results differed from the ideal circulation. The increase of the thrust of the interstage combustion chamber requires a similar incremental consumption under subsonic conditions The fuel consumption and supersonic speed increase the same fuel consumption by about 10%. Its economy and maneuverability are between the conventional engine and the engine with the afterburner. Finally, the parameters of the engine with the interstage combustion chamber are optimized.
