翼型翼的横剖面形状,又称翼剖面。在空气动力学中,翼型通常理解为二维机翼，即剖面形状不变的无限翼展机翼。低速和亚声速翼型的典型外形如图所示。它前端圆滑，后端成尖角形；后尖点称为后缘；翼型上距后缘最远的点称为前缘；连接前后缘的直线称为翼弦，其长度称为弦长。在翼型内部作一系列与上下翼面相切的内切圆，诸圆心的连线称为翼型的中弧线，其中最大内切圆的直径称为翼型的厚度；中弧线和翼弦之间的最大距离称为弯度；前缘的曲率半径称为前缘半径。超声速翼型的前缘也可能是尖的。翼型的相对厚度和相对弯度分别定义为厚度和弯度对弦长之比，弯度为零的翼型称为对称翼型，其中弧线与翼弦重合。当翼型相对于空气运动时，翼型表面会受到气流的作用力，其合力在翼型运动方向或来流方向上的分力是翼型所受到的阻力，垂直于上述方向的分力是翼型的举力。 这些作用力对前缘（或对距前缘1/4弦长点）的力矩称为俯仰力矩。在低速和亚声速情况下，还有一种翼型叫作层流翼型，它的最大厚度较靠后，边界层的层流段较长，因而摩擦阻力较小。在跨声速情形下，有一种翼型叫作超临界翼型，它的上表面比较平坦，翼面上一般只产生压缩波和膨胀波，间或有弱激波，因而波阻较小。
