If the conveyor is stationary, where would airspeed come from?Yes it can - the airplane will have to overcome the speed of the conveyor with enough airspeed to create lift on the wings. But, the tires will probably fail before that.
My simple mind tells me this too. The argument is that the thrust is not connected to the wheels so it takes off.If the conveyor is stationary, where would airspeed come from?
The airplane can’t overcome the speed of the conveyor since the theory addresses that the conveyor is designed to exactly match the speed of the tires.Yes it can - the airplane will have to overcome the speed of the conveyor with enough airspeed to create lift on the wings. But, the tires will probably fail before that.
If the conveyor is stationary, where would airspeed come from?
Exactly! It won't be able to "take off" but it sure would fly... off the end of they conveyor if you stopped it fast enough.The wheels would have to spin faster than the conveyor in order to create lift, this can’t happen if the conveyor matches the wheel speed.
The airplane has it's own power right? Consequently, it can take off.If the conveyor is stationary, where would airspeed come from?
Ah but you miss the point that the engines are moving the airplane forward down the conveyor (runway) which creates air flow over the wings and consequently lift. The conveyor is simply "matching the speed of the wheels in the opposite direction". The conveyor, quite possibly, isn't moving at all.Negative. "They belt conveyor is designed to match the speed of the wheels". Therefore it ain't going anywhere... no lift.
If the engines were off and you turned on the conveyor, what would happen? The plane would move backwards. Now if you turned on the engines to counteract the conveyor moving backwards then the plane would be stationary, correct? Now say you sped up the conveyor so now the plane starts to move backwards again. You would have to give the plane more thrust to counteract the conveyor, correct? At what point does the plane create airflow to take off from the ground?
