The U.S. Air Force, one commentator has written, has put them in wind tunnels to see how they do it, and despaired.

“美国空军，”有一位评论员写道，“把它们放在风洞里，看看它们是怎么表现的，结果感到望尘莫及。”

[Derek] We made a separate video on Adam's channel that discusses the wind tunnel in more detail.

- [Derek] 我们在 Adam 的频道上制作了一个单独的视频，更详细地讨论了风洞。

Putting the bats in wind tunnels where their breath could be monitored as they flew was too challenging.

将蝙蝠放入风洞中以便在它们飞行时监测它们的呼吸太具挑战性。

So they built a wind tunnel two meters long in their bicycle store in Dayton, Ohio. They tested more than two hundred designs of wings.

所以他们在位于俄亥俄州自己的自行车商店里做了一个两米长的风洞。他们对设计的两百多种机翼进行测试。

We've done some tests in wind tunnels and all the studies have found that there may be a very small advantage to it.

我们已经在风洞中进行了一些测试，所有的研究都发现头冠可能对于飞行辅助的优势很弱。

This phenomenon led engineers to begin testing models of tall buildings in wind tunnels at design stage, assessing the potential impact of high winds on structures before they were constructed.

这一现象导致工程师们开始在设计阶段在风洞中测试高层建筑的模型，在建造之前评估大风对结构的潜在影响。

They began by building a wind tunnel in their workshop in Dayton, which allowed them to test the aerodynamics of different wing designs and control surfaces.

他们首先在代顿的车间建造了一个风洞，这使他们能够测试不同机翼设计和控制面的空气动力学特性。
