迎角又称“攻角”。是指飞机速度方向线在飞机对称平面内的投影与机翼弦线之间的夹角。飞行时,作用在机翼上的空气动力与迎角有关。在一定迎角范围内,增大迎角,升力系数和阻力系数都增大。为了获得支持飞机重力的升力,飞机高速飞行时以小的正迎角飞行,飞机低速飞行时以较大迎角飞行。 基准迎角的计算公式为W/Cl*Q*S

Within the field of ground effect, aerodynamic forces of the wing-in-surface effect crafts are not only decided by the angle of attack, but also by the flying height, and they lead to more complicated stability problems.
在地效作用区域内,地效飞机的气动力不仅与迎角有关,而且与飞行高度有关,因而其飞行稳定性问题更为复杂。
