Plane on a conveyor belt
-
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.

Why would the plane not move though? The wheels do not propel it forward, otherwise it would not fly. It will 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.

Dammit, this thread was put to bed... who woke it up?
Bassplayer, you are making the mistake that a plane and a car are propelled the same way. You are correct that a car will be stationary on a treadmill, because it is driven by it's wheels (which are tied to the treadmill). A airplane will not be stationary, because it's driven forward by a propellor or jet. It doesn't matter how fast you have the treadmill spinning under the airplane because the wheels on an airplane just free-wheel. The plane will start moving forward just like always (except the wheels will be turning like a mofo on the treadmill), gain airspeed, and take off.

Now, what is going to make the car go 100mph?
Put it in neutral and the wheels spin at 100mph cause thats how fast the treadmill is going?If you set a hotwheels on a treadmill and turn it off, what happens? It will just fly of the end. If you would strap it down, it would stay still and not move.
This is talking about having the treadmill speed match the speed that the aircraft is moving(doesn't matter what kind). If the aircraft is going 1mph forwad the treadmill would be going 1mph in the oposite direction........... same thing goes for 100mph, and even 1000mph.

That was exactly my thinking when this thread first started. Unfortunately, you're forgetting that the wheels don't make the plane go forward, the jets or propellers do, and they're not connected to the wheels in any way.

Read my responses. The plane moves forward relative to the ground and there isn't a darn thing the conveyor belt can do to stop it. So long as the conveyor belt is long enough for the plane to accelerate to take off speeds, the plane takes off. Basically, the plane is as likely to be stopped by the wheels rolling along the conveyor belt as it is to fall out of the sky every time it flies over a conveyor belt.
