| 摘 要： | 基于进气道/发动机推进系统一体化动态数值模拟计算系统,对飞机快速俯仰机动飞行过程中的性能进行了计算分析研究,获取了飞机快速俯仰过程中的推进系统气动性能的变化特征,数值计算结果表明:快速变化的外部扰动会诱发发动机内部热力循环参数和性能更大的动态波动；在机动飞行的同时,增大燃油量,发动机推力下降程度得以减缓,发动机的单位燃油消耗率上升. |

| Abstract: | Based on an air inlet/engine integrated dynamic simulation system,the engine performance parameters were investigated and obtained in fast maneuvering flight.The numerical calculation shows that fast-changing exterior turbulence reflects on more dynamic fluctuation of thermal cycle parameters and performance parameters,due to the history of engine fuel mass flow,engine thrust descend degree minishs,on the contrary,engine specific fuel consumption ascends with increase of attack angle. |
| Keywords: | highly maneuverable aircraft aircraft/engine matching air inlet/engine matching integrated design coupled calculation |
