| 摘 要： | 建立了微下冲气流影响下的飞机运动的数学模型,用数值方法分析了微下冲气流对飞机滑跃起飞的影响。结果表明微下冲气流对飞机滑跃起飞性能有明显的影响,特别是微下冲气流中心的位置对飞机滑跃起飞的影响十分显著。如果飞机离开斜板时处于顺风微下冲气流场,那么飞机的爬升高度和爬升率将严重下降,对飞机的滑跃起飞性能产生不利影响。

| Abstract: | The mathematical model of aircraft ski-jump takeoff with the influence of micro-downburst is established in the paper,and the influence of micro-downburst on aircraft ski-jump takeoff was analyzed using numerical method.The results indicate that aircraft ski-jump takeoff can be obviously influenced by micro-downburst,especially by the position of its center.If the aircraft take off in the tailwind field,the climbing height and speed will decline badly,and micro-downburst will bring negative influence on aircraft ski-jump takeoff. |
