How to pronounce “wind tunnel” in English

The wind tunnel-- the wind tunnels are a really core part of what we do.

And wind tunnel and sim data often gives you a direction, but there's quite a few times where it's wrong, and so you're trying to spend a lot of time

- Typically this wind tunnel is used in the development of advanced wing geometries for innovative sustainable aircraft design.

But the wind tunnel gave LeMessurier a dynamic analysis, how the forces change when the building is moving around.

- So this is the low-speed wind tunnel here at the university.

- You can see this in the wind tunnel.

This shot is from the inside a wind tunnel.

This is last week in the wind tunnel with Team Ineos.

So we went into the wind tunnel, and we optimized that bike by producing some 3D printed packers to change all of the tube profiles to get more out of the sailing effect,

And that's all measurable in the wind tunnel.

These flights were tested hundreds of times in JPL's wind tunnel, and tens of thousands of times in simulation.

And all of these athletes come with us in the wind tunnel.

So we've had over 100 athletes in the wind tunnel in the last few years to learn, which is some of the tips I'm going to try and give

So the idea there is not everyone can go into the wind tunnel, so we want to take the wind tunnel to the end consumer.

This is world champion Patrick Lange in the wind tunnel with us.

And so here's a picture of me in the wind tunnel having a bit of a play.

So a more serious example-- I did a test in the wind tunnel.

He was an engineer in the full scale wind tunnel at Langley.

To LeMessurier's horror, the wind tunnel analysis showed that the stresses could increase up to 60% more than originally anticipated.

LeMessurier squirreled himself away in Maine and worked through the data from the wind tunnel again, joint by joint on every floor.

literally it's a-- the relationship of the hours spent in the wind tunnel to the amount of improvement is almost linear.

And so we developed a special load cell and a special balance for our wind tunnel, where we can actually measure that.

So that's the type of things that we measure in the wind tunnel.

And I managed to take one of those bikes and those wheels into the wind tunnel, as well as some suits and a proper time trial helmet.

But what we can say and what we do see in the wind tunnel with our testing is that a suit that

ended up completely rusting a brand new, expensive wind tunnel.

So armed with this data, let's analyze Brady's throws in a wind tunnel.

where cars and airplanes are tested, down into the wind tunnel down in San Diego.

Certainly at that time, structurally, it was the best wind tunnel in Formula One.

basically aerodynamics in the computer, as well as our wind tunnel testing, which is really the cornerstone of what we do.

Here's one of our athletes, Laura Phillip in the wind tunnel with us just a few weeks ago.

So what do we measure, whether it be in safety or in the wind tunnel?

This is what a graph looks like, whether it's in the wind tunnel or out of CFD.

And like this, one of the problems of testing in the wind tunnel is you get a result.

And from then on, he went on to build the world's first functional wind tunnel, which is at the base of the Eiffel Tower,

To find out why, we ran a full computational fluid dynamics analysis, tested spinning balls in a wind tunnel, and even embedded sensors in real footballs.

And today, we're gonna see whether his findings hold up by simulating Tom Brady's own throws in a wind tunnel.

He didn't wanna rush to conclusions, so he flew to Canada to check his calculations with Alan Davenport at the Boundary Layer Wind Tunnel.

I was like, I couldn't find any data on how a steak tumbles at hypersonic speeds, but if you have a wind tunnel capable of those speeds,

we were just finishing our doctoral research, and we had a couple of hours left on the wind tunnel.

And they did mention that, after they were done, the entire inside of the wind tunnel had flecks of raw meat all over it,

But if you're there, where I feel like I transcended to that top step of the podium is saying, OK, so I took my bike down to the wind tunnel

And we can quantify this with these sorts of rakes, which gives us a really important correlation between real world, wind tunnel, and also CFD approach.

I actually did, two weeks ago, a test with an athlete in the wind tunnel where we built, from a 2 by 11 to a 1 by 12 system, step by step removing all the parts,
