| 摘 要： | 坡度是飞机由于左右机翼升力不一致,绕纵轴滚转而形成的一定角度。现代大型运输机机翼翼展长,发动机离地面较低,如果低高度坡度过大,可能擦翼尖或发动机。另外,着陆时坡度过大还会造成单侧主轮接地而导致垂直过载偏大,影响方向的控制,危及飞行安全。就坡度的成因进行研究,并且给出了几种修正方法,理论与实践相结合,达到安全飞行。

| Abstract: | Gradient is the angle caused by the inconsistent rising forces of left and right wings.Modern large cargo planes have long wings,and their engines are barely above the ground.If the gradient is too big,the ground may scrape the engines and wings.In addition,too big gradient in landing can also lead to the friction of the main wheel at one side with the ground,thus resulting in high vertical overload,and affecting the control of direction and endangering flying security.The article studies reasons for the fo... |
