Now if we could only get them to put a jet airliner on the treadmill, we could finally answer that question from the thread on whether a jet on a treadmill would take off or not...

Re: 180MPH NASCAR Treadmill - finally an answer to the jet-on-a-treadmill debate?
if you put an airplane on there... would it take off ????
LOL
here we go again..
looks like a photochop to me

Nope, this one is real, not Photoshopped. It was built by Haas CNC Racing in conjunction with Jacob's Technology, a subsidiary of Jacob's Engineering. It's the first of its kind and is known as WindShear, Inc. It will ultimately be placed in a wind tunnel.
The rationale for this is due to the inherent inadequacy of boundary layer control for near ground surface wind velocities as generated in a wind tunnel. In addition, it permits analysis of suspension and tire interaction with the surface, at speed, in a controlled, real-time environment.
Oh, and for the umpteenth time an aircraft would takeoff as the motive force is thrust induced and not traction dependent as it is with a normal vehicle. The hypothetical treadmill is therefore irrelevant.
Re: 180MPH NASCAR Treadmill - finally an answer to the jet-on-a-treadmill debate?
It does not matter to a plane how fast its wheels are turning. The only way to generate lift is with wind under the wings.
It is possible for a plane to be going backwards across the ground if the winds into which it is flying are greater than the plane's indicated air speed. I've done that.

If a treadmill was set up for the space shuttle in the same way as the hypothetical jet-on-a-treadmill, would it still take off and be able to reach orbit?
Oh, the treadmill is pretty cool but nothing like driving on the track to test a vehicle.

It's amazing what money can buy. I also like the "high-tech" cable protectors (a.k.a. plywood boxes)
Oh, and it is air speed - not ground speed - that makes a fixed-wing aircraft fly.

NO Doubt, why did you do this? ...............You know you are starting it again. ..........Shame on you.
Thrust does not produce lift, lift is produced by differential pressure (top and bottom) on the wings. To have this differential pressure, the airplane need to be moving. In a threadmill, the airplane is not moving, so it is not taking off. Rauchy is correct.

i agree with this statement.
lift is caused by the wind beneath my wings..
hmmm
soundsl like a song

Bingo!!!
You just can't explain any easier than this.
Rocket........you're a bad man to start this over again!!!
You just weren't happy were you???!!!
