Can A Plane Take Off On A Treadmill?

small plane, of course!!! bigger plane, nope... it has nothing to do with the speed of the wheels, so much as the air flow beneath the wings to lift it up, so, nope, impossible.

your wheels could go at mach 45, wouldn't change the fact that you have no air pushing the plane upward....
 
I don't think so; I believe you need to have the plane moving to have it lift up. Without the lift force against the wings, I don't think it can rise up.
 
No !

Since you have equilibrium, there is no lift !

And this also why they have fans installed on those fancy pansy thread mills to keep you cool since your not getting any draft whiel running on it.

Well a plane could take off on a treadmill if there is sufficient wind.

Yes, if the wind is suffcient to counter the drag and gradually increases to match the speed/thrust of the plane to provide lift until it can get its own air speed.
 
If the treadmill was as long and wide as a runway yes it could. It doesn't matter how fast the treadmill is spinning, a planes thrust comes from the jet blast created by the engines, not the wheels. Even if the treadmill is spinning at 1000kmh, the plane could take of as normally as it would on a stationary runway.

However, the question gets confusing because everybody is thinking about a small personal treadmill, so the question is ****ed because it gives the impression that you're setting a big jet on a five foot treadmill expecting it to take off stationary.

Theoretically it's possible, realistically, there is no treadmill long enough for a plane to roll on for it to be possible.

actually, that's wrong, the thrust doesn't lift the plane, it just pushes it forward fasterso to create the negative flow faster thus getting up in the air faster


so no, impossible, as long as you have friction and gravity, without wind, you'll stay grounded. PERIOD

threadmill or no threadmill


look at it this way, you wouldn't even need a runway or threadmill if the negative flow was strong enough I.E. (kite)
but for a comercial plane, not even mount washignton's 300+km/h winds could even remotely lift it up :p

so we need to create that negative wind, thus the runway and thrust...
 
hmmm depends....is the treadmill motorized? Meaning does the treadmill increase its speed accordingly to match the thrust of the engines? Or is it just one of those feespinning treadmills with no motor?
