如何区分飞机的襟翼、副翼、升降舵?

飞的姿态操纵是由升降实现舵、方向舵、副翼此三舵操纵飞机沿三个转轴,转动。1.纵轴(从机头中心点到机尾中心点的连线垂直于横/立轴的直线)
2.横轴(从机翼左右沿气动中心的轴线且垂直于纵/立轴的直线)
3.立轴(从飞机的上表面穿过气动重心倒下表面且垂直于纵/横轴的直线)
以上三条直线是想象的直线,它在物理上并不存在,但是在飞机的操纵运动规律上确实存在的。
其中升降的使得飞机沿横轴发生转动。而襟翼的作用是增加机翼的升力,它的作用不是使飞机沿轴向转动而是使飞机沿立轴产生水平的上下运动。

襟翼主要是用在飞机起飞和着陆时增大升力用的,其原理是增大弯度使升力系数增加!一般说来,弯度增加越多,升力增加也越大,但阻力相应会越大,所以飞机起飞和降落时襟翼偏转的角度是不一样的:起飞时偏转角度较小,大约在20度左右,降落时偏度较大,大约在35度左右。
升降舵的原理与襟翼类似。只是襟翼只能向一个方向(只能向下)偏转,而升降舵可以上下偏转
