飞机的机翼有各种形式,除了平直翼以外,还有前掠翼、后掠翼、变后掠翼、斜机翼和X翼等。它们有一个共同特点就是都有掠角(前掠角或后掠角),因此我们把装有这些机翼的飞机统称为掠翼飞机。本文将从纵横两个方向,来谈一谈掠翼的由来与作用和各种掠翼飞机的特点与发展。 There are various forms of aircraft wings, in addition to the straight wing, there are swept front wing, swept back wing, after swept wing, inclined wing and X wing and so on. One thing they all have in common is the sweep angle (sweep angle or sweep angle), so we will refer to these wings as aircraft. This article will talk about the origin and function of swept wing and the characteristics and development of various swept wing aircraft from both vertical and horizontal directions.
