lift must be more than wieght, drag must be less than thrust or else you wont fly anywhere, seems how no lift will be created, you cannot fly dont yall get it????
The plane will roll and gain speed, don't you all get it? The wheels have no way of changing the forward motion of the plane. They just spin.

The wheels are just idlers used for steering and ease of movement.

if the conveyer belt is the distance of a normal run way and it travles the whole distance then it does not matter how fast or slow the conveyer belt is moving. it still moved its required distance at take off.

There is no required distance to take off. Speed is the only thing required. In this case the engines should move enough air into the flaps and slats to lift the aircraft.

so your saying i could sit in one spot with the wheels moving and it will take off? no it wont. even with the engins at 100% its till does not have the power to lift it at a dead stop even with the flaps down.

it needs the distance to get the required air speed for take off. the conveyer belt dose nothing it might as well not be there.

there is no plain in the would that would have enough power to lift the plane on just the engines and the flaps. not even a jet. excluding hovering plains.


if i had a tried mill i would try it with my rc plane. altho power to waight might efect somethings.

just like the gif showed the plane whent from the start of the conveyer belt to the end taking of at the end. not in the middle or start but at the end.

The plane will NOT take off. If the conveyor belt matches the speed of the wheels at all times (in the opposite direction, the plane wouldn't move forward and if the plane is just sitting in one spot there is no wind to go over the wings therefore the plane cannot not make lift, even if the engines were super powerful the plane would just sit on the ground increasing the speed of the wheels and the conveyor belt. And the wind would be the same, you can't fly a plane from a dead stop you need to move forward to createwind so the wingscan do their job and create lift.The motors don't fly the plane, the wings do.

He is correct. Without airmovement there is no way possible the plane could fly. basically it would be the largest treadmill in the world. The people who said the the wings create lift are correct but its because the air passes underneath of them. because the plane is essentially stationary = no air movement = no lift
