[quote= “The Question”)This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same.[/quote]
Actually, my example above with the pulley that pulls the toy car, and at the same time drives the conveyor backwards answers the question. And satisfies the constraints of the question as well.
The plane moves. If the plane can move, it can take off.
Hell, tie a cable on the back of the plane to the rear roller of the conveyor (you’ll have to wrap it underneath. See it?) As the plane moves forward, it pulls the conveyor backwards under its wheels. Here is another system that satisfies the constraints of the question and the plane takes off.
