Oct 27, 20070183;32;The plane will not stay on the conveyor belt. The power of the plane comes from the jet engines or the propellors, not the wheels. The conveyor belt, no matter how fast it is going, will have no effect on the motion of the plane. The plane will move forward because it is pushing air, not because the wheels are making it move.
In contrast, a planes wheels arent motorized; their purpose is to reduce friction during takeoff (and add it, by braking, when landing). What gets a plane moving are its propellers or jet turbines, which shove the air backward and thereby impel the plane forward. What the wheels, conveyor belt, etc, are up to is largely irrelevant.
Imagine a 747 is sitting on a conveyor belt, as wide and long as a runway. The conveyor belt is designed to exactly match the speed of the wheels, moving in the opposite direction. Can the plane take off? The practical answer is yes. A 747s engines produce a quarter of a million pounds of thrust.
Nov 21, 20170183;32;But the weight of the plane on the conveyor belt remains the same. No air moves across the wings, so the plane does not lift and cannot take off. If the conveyor belt reaches 200 or 300 or 500 miles per hour, the plane will still be in the same spot. All the engines are doing is preventing the the airplane from moving backwards.
For those of you just joining us, quot;Airplane On A Treadmill,quot; also known as quot;Airplane on a Conveyor Belt,quot; is a thought experiment in physics. Some consider it a litmus test for assessing one's knowledge of airplane physics. In its most basic form, the experiment is worded thusly A plane is standing on a large treadmill or conveyor belt.
3Nov 30, 20050183;32;Anyways, this problem is obviously pretty difficult to visualize. I still hold, however, that the force exerted on the plane by the conveyor belt moving backwards is quite small, since the wheels can spin freely. Thus the aircraft will be able to move forwards, relative to the air, and take off regardless of the speed of its wheels.
Jul 17, 20160183;32;Some people just assume that the conveyor belt will move the plane back. The job of the conveyor belt is in both cases mostly limited to rotating the wheels. Try it at home You do not need a plane and a conveyor belt. Just get a medium size tube. Or a bottle. And place it on a smooth surface (a large sheet of packing paper is easily available).

I like this question It made me think. If there were a way, Id vote the Question up, along with almost all the answers (b/c they made me think harder). So, my answer The plane will not take off if it remains in full contact with the conveyor be

Well, the tyres exploding at some point before V1 might inhibit the takeoff (as the wheels will end up rotating twice as quickly as they normally would as the plane accelerates down the conveyor belt, so the wheels will be rotating well above their maximum rated speed by
Plane on a Conveyor Belt. Myth A plane on a conveyor belt, matching its takeoff speed in reverse, can't take off. This is a Internet meme popularized by sites like kottke.The original problem states that the conveyor belt matches the forward speed of the plane in reverse, but for this particular mythbusting they tested the conveyor belt moving at the plane's takeoff speed.
The plane could be on a runway, a conveyor belt, a set of flatbed lorries, thirty thousand roller skates or a magic carpet it doesn't matter. The engine thrust *alone* propels the plane forward relative to the air, and when the airspeed exceeds that necessary to provide lift for flight, the plane
But I agree that the plane will move forward and once its air speed is sufficient it will take off. The wheel speed is irrelevent and will always match the speed of the conveyor belt provided the wheel is not skidding. The gotcha is the misconception that by spinning the conveyor belt you will somehow prevent the plane from moving.
