glad you asked...How long were you sitting on that one?

Dammit Dave, answer my post about a jet engine on a Supra!!!
That's a dumb question, because if a jet and a Supra were to swap powerplants, the Supra wouldn't be as fast as it normally would and the 2JZ would make the jet so fast that it's wings would fall off and it wouldn't get off the stupid conveyor belt.
Duh!

I disregard my last answer...I agree with tjamz, My teacher is VERY wrong and yes the plane WILL fly, I talked with my dad about it last night and he knows VERY well about this stuff so he gave me an example.
If a train (a train big enough for a plane to land on) is moving 200mph -------------->
and a plane is moving 200mph<-----------and the plane somehow lands on this train will it stop flying?......the answer is no, just because the wheels are moving doesnt mean it isnt flying, the wheels are just moving faster so the plane doesnt really care if its on a conveyor or not, in the end it will take off!!!
Thank you education system:icon_scratch:??
This must prove that parents know more than teachers think they do....lol -
Tell your dad I said thanks,

Tjamz has my end covered! The plane will fly!

I have gone over this before, and i don't feel like reading everything, but yes it will fly because wheels have nothing to do with a plane flying as long as the wind moving across the wings is fast enough to lift it. The wind moving over the top goes faster (less pressure when air is moving) so there is more pressure below pushing it up. How would float planes and ski planes work with no wheels??

I'm just wondering how the plane gets enough lift to raise it. If its not moving than the only air would be that from the propellor. Idk we'll what happens this wednesday, I'd say depending on the plane it won't talk off. If they get an F16 theres no way any belt can go 800mph and that would take off.

It can "match the speed" in the opposite direction, but that does not mean that the plane isn't moving (in fact it HAS to be moving for the belt to move in the first place). What it CAN do is spin the wheels at twice their normal rate, but this will have virtually no affect on whether the plane moves forward or not....it might shorten the life of the tires and/or bearings, but that is all.

^^^^Im with the 2 above me, since when have wheels had anything to do with how a plane is propelled??
How would ski planes or float planes work then??

The wheels have no part other than move the plane.....they are not a part of the plane.....no power to wheels.

Wtf i never said anything about the wheels. Bernoulli's principle defines lift, and if there isn't low velocity below the wing creating high pressure than the plane won't rise.
Ex if you're running on a tread mill is there wind going by you? NO there isn't.
Ex2 If you drive a car on a tread mill at 100mph and stick you're head out the window will you feel any thing? NO
Its not going to fly.
