| 摘 要： | 针对飞机在下滑着陆阶段穿越微下冲气流的问题，建立了微下冲气流影响下的飞机纵向运动数学模型。用数值方法计算了微下冲气流对空速、迎角和航迹的影响，结果表明，飞机在穿越微下冲气流时，空速、迎角、下滑航迹变化很明显，飞行员操纵和判断的难度会增大。特别是顺风阶段，航迹比正常偏低很多，对飞机的安全着陆影响很大。

| Abstract: | The mathematical model of aircraft motion with the influence of micro-downburst was established in this paper, and the influence of micro-downburst on aircraft landing performance was analyzed using numerical method. The results indicated that aircraft landing performance could be obviously influenced by micro-downburst. When the aircraft crossed micro-downburst, its airspeed, angle of attack and glide track would change obviously, the difficulty of control and esti- mate for pilot would augment. Especially in tail wind, glide track was much lower than normal condition, it would bring det- rimental influence on safety of aircraft landing. |
