drag do efficient 阻力系数
A modern sports glider, with long, slender wings, is the most aerodynamically efficient aircraft, with a lift-to-drag ratio of around 50:1.
现代运动用滑翔机的机翼长而细薄,拥有最佳的空气动力学效率,其升阻比达到50:1。
There is little in the way of future predictions, apart from the suggestion that aeroplane wings may soon have bristles, a "fuzziness" that would reduce drag and therefore be more fuel-efficient.
他几乎没有对未来做预言,除了暗示飞机翅膀可能很快就会有短毛,因为这种“羽毛特性”会降低拖力,因而更节约燃料。
Strong in the sense that it 's designed to withstand high speed deployment, and efficient in that it provides for a high drag force for a given size and weight.
在强烈的责任感,它奇摩设计足以承受高速的部署,和有效率的,因为它提供了一个高阻力为某一特定的尺寸和重量。
