We are essentially burning the airfoil as we fly it.

在我们飞行时，我们实质上是在燃烧机翼。

The wires in front and airfoils in the back both carry high electricity – up to 20,000 volts each.

前面的钢丝和后面的叶片剖面均带有高压，最高电压均为200伏。

It might even alter its trajectory with an airfoil or mini compressed-gas thruster.

它甚至可以通过翼面或小型压缩气体推进器改变自身轨道。

The electrodes in the front are made of thin wire. In the back, they take the form of thicker airfoils.

电极前面由细钢丝制成。后面则采用了较厚的叶片剖面形状。

In the back, they take the form of thicker airfoils.

在后面，它们采用较厚的机翼形式。

I mean, you really have to have an airfoil to make it a lifting surface.

我的意思是，你确实必须有一个机翼才能使其成为升力面。

At that speed, the surface of the airfoil is the temperature of molten steel 3,500 degrees Fahrenheit like a blast furnace.

在这个速度下，机翼表面温度是钢水的温度，华氏3,500度，就像一个高炉一样。

It's acting like an airfoil in the back.

它的作用就像后面的机翼。

I'm... so, I take back everything I said about it not acting like an airfoil.

我… … 所以，我收回我所说的关于它不像机翼的一切。

You wanna fly one of these, you gotta be familiar with airfoil, drag, lift and thrust...and these are all principles of aerodynamics.

要想成功让它飞起来，就必须了解螺旋桨 、拉力、空气浮力和推力等等，全都是航空动力学的基本原理。

Based on the Eurocopter AS332L2 Super Puma, it features a five-bladed main rotor and a modified airfoil shape that reduces vibration levels.

它基于欧洲直升机公司 AS332L2 Super Puma，具有五叶主旋翼和改进的翼型形状， 可降低振动水平。

NARRATOR: The wing feathers are asymmetrical, with veins wider on one side of the shaft than the other, which forms an airfoil contour, like an airplane wing.

旁白：翼羽不对称，羽轴一侧的叶脉比另一侧宽，形成翼型轮廓，就像飞机机翼一样。

So where you see a typical flight feather that has a closed vein and an offset rachis to give it an aerodynamic airfoil shape, the ostrich is have done away with that completely.

所以如你所见这是一个典型的飞行羽毛，有一个封闭的静脉和一个偏移的羽轴给它一个符合空气动力学的翼型形状，鸵鸟已经完全失去了这种羽毛了。
