The modern airplane design works well, but from a fuel efficiency standpoint, could planes be designed more aerodynamically — to lower drag and increase lift?
现代的飞机设计做得很好,但立足于燃料效率来看,飞机是否能设计得更符合空气动力学——降低阻力还是增加动力?
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。
When it comes to the phenomenon of face-lift, which is nothing new but still hot-discussed in this modern society, there is no complete agreement among people.
