The Upturned Wing Tip of Soaring Birds

A JET plane in flight creates rapidly spiraling swirls of air at the tips of its wings. These vortices cause drag, increasing fuel consumption. They also buffet planes that may be following closely.

飞机 在 飞行 时,机翼 的 尖端 会 产生 急速 的 气流 旋涡。这些 涡流 会 产生 阻力,增加 油耗,也 会 冲击 紧 随 其 后 的 飞机。

Airplane engineers have discovered a way to reduce these problems. Their solution? Winglets, inspired by the upturned wing-tip feathers of soaring birds, such as buzzards, eagles, and storks.

飞机 工程师 已经 找 到 一 个 解决 方法,他们 从 鸟翼 尖端 翘 起 的 羽毛 得到 启发,在 机翼 的 尖端 安装 小翼。秃鹰、雕、鹳 等 会 滑翔 的 鸟 都 有 这样 的 羽毛。
