Ok.
The Conveyor moves at the same speed as the planes wheels.
They both start stationary, then the plane starts its engines. To begin with the conveyor is stationary because the planes wheels are stationary so the thrust of the engines pushes the plane forward.
The conveyor then reacts and goes the other way, slowing the plane down but before it can stop it completely the speed of the plane and hence it's wheels has dropped and so the conveyor slows down too.
This then allows the plane's engines to thrust it forward again. The planes speeds up - the conveyor speeds up - the plane slows down etc etc.
So I reckon how the plane moves depends on how quickly it accelerates and how quickly the conveyor accelerates and reacts but in short the plane will move forward but the conveyor's reactions will stop it taking off before the end of the runway.
That's my take on it anyway. |
