The plane would still move forward until the wings created enough lift for it to take off but the wheels would never turn since the treadmill would be matching their speed but in the opposite direction…the wheels not turning would have no effect on the plane taking off.
Maybe the plane would take off just a smidge sooner because none of the energy/thrust put out by the engines would be wasted energy put into spinning the wheels against the ground while getting the plane up to speed.
Exactly…. Just imagine a boat plane or snow plane. That’s also why the conveyor belt had to be as long as the runway.
the treadmill is not going to counteract the thrust of the engines. the plane will not stay stationary on the treadmill regardless of what the wheels do. standby for takeoff.
An airboat is caught in a very strong current which just happens to equal the boat's top speed. When the boat is at top speed, it is thus stationary to an outside observer on the riverbank. Same with the 747.
The plane might move forward or backward. It is unknown it it is anchored. The conveyor belt has a limit in length. Therefore the plane will fall off the belt.
