Back wing
回翼───Back wing
In the old days, a designer working on an airplane wing handed a bunch of punch CARDS to the computer operator and waited a week to get back thousands of Numbers on fanfold paper.───那时候，一个设计飞机机翼的工程师会把一大堆穿孔卡片交给电脑操作员，等上一个星期才能拿回来成千上万的数字，而且是写在复写纸上的。
variant of the swept-back wing is the delta wing.───后掠翼的变型是三角翼。
Vibrating in the wind, the bristles create some drag. But they also reduce the wing's slipstream, an area of low-pressure turbulence that pulls back on the wing, and hence reduce drag.───振动时，刷毛会产生反作用力，但同时它也可以减少机翼滑流，产生一个低气压乱流，机翼上形成回力，因而减小阻力。
In addition, the rolling damping of folding wing is smaller than that of diamond back wing.───钻石背弹翼的外形滚转阻尼力矩系数最大。

Usually think so, want to fly, will find back wing;───常常这么想，要想飞翔，就要找回翅膀；
A variant of the swept - back wing is the delta wing.
Its name will feature prominently on the 1993-95 Lotus cars' back wing as well as the drivers' racing suits.
