补充资料：机翼
飞机的组成部分，其主要作用是产生支持飞机重量或作机动飞行所需的举力。机翼的空气动力性能取决于机翼的外形、飞机飞行速度和飞行姿态。机翼外形用一些几何参数描述。翼的横剖面形状，称为翼型。从翼根到翼梢，翼型不一定相同。各剖面的翼弦也不一定在同一平面上，这称为机翼的扭转。机翼在顶视图上的形状称为机翼的平面形，典型的平面形如图上部所示。从一翼梢到另一翼梢的长度称为翼展，通常记为l；Cr、Ct为翼根和翼梢的弦长；机翼面积记为S； 翼展与平均弦长(S/l)之比称为展弦比(λ＝l2/S)。机翼的前缘和后缘都可以有后掠角。低速飞机和亚声速飞机的后掠角，通常是指各剖面的1/4弦长点的连线 （图中的虚线）与机翼对称面垂线之间的夹角,记为χ1/4。负的后掠角称为前掠角。超声速飞机的后掠角通常指机翼前缘的后掠角。左右两半机翼不一定在同一平面上，半翼的中间平面和横轴之间的夹角θ称为上反角(见图下部)。按展弦比,机翼可分为大展弦比机翼和小展弦比机翼；按掠角，可分为前掠机翼和后掠机翼。
