后掠翼

后掠翼是机翼设计的一种型态,特指机翼沿着翼展方向的轴线与机身具有一个向后的角度,即掠角为锐角。机翼的后掠程度由后掠角大小来进行表示。 后掠翼是平直机翼发展而来的,适用于较高的飞行速度,气动特点为可增大机翼的临界速度,并减小超音速飞行时的阻力。

后掠翼的理论最初由德国人在1930年代提出,第二次世界大战期间,使用后掠翼设计的飞机开始出现,包括德国的Me 262战斗机和Me 163战斗机。但是Me 262使用后掠翼的原意并非针对高速飞行下的控制。

第二次世界大战之后,随着飞行速度的提高,后掠翼和其他适合高速飞行的机翼同时受到广泛的注意,但是随着使用经验的累积,后掠翼逐渐成为1950到1960年代很常见的设计之一。

Swept wing 後掠翼

A B-52 Stratofortress showing its swept wing.
A Burgess-Dunne tailless biplane: the angle of sweep is exaggerated by the sideways view.
Adolf Busemann, proposed the use of swept-wings to reduce drag at high speed, at the Volta Conference in 1935.
The de Havilland DH 108, a prototype swept-wing aircraft, produced in 1944.

A swept wing is a wing which angles either backward or, occasionally, forward, from its root rather than in a straight sideways direction. Wing sweep has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore often used on jet aircraft designed to fly at these speeds. Swept wings are also sometimes used for other reasons, such as structural convenience or visibility.
