So if this was on a conveyor belt... would it take off?

 

that doesn't even make sense, since the force you are applying is still using the ground as a bench mark for push or thrust. A plane "pushes" against the air...the conveyer belt can be going 2034823048 mph in the oposite direction of the plane who cares, all it is going to do is spin the wheels on the bottom of the plane faster, it has no effect on the thrust of the engines using the air as a wall to push off of to accelerate.

it will lift off, but it won't fly for long given the situation. /thread.

 

People that think the plane will take off make me laugh.

 

Don't say that, Pete. Look at the picture! Read my words!


Let me try and explain this at simple as I can. The wheels touching the conveyor have no impact on the plane. The landing gear system is low-impact to the airframe. Essentially, the airframe is suspended in air. The wheels are just a means to reduce the friction during normal take-off. In this case, the wheels will spin twice as fast as normal, however, the thrust of the engines will still propel the airframe forward to attain lift and take-off.

 

So if a plane had no wheels, it would still take off? I see what you're saying, but the plane is heavy and all the weight is on the wheels. just because the wheels are spinning doesn't mean there is any less weight on them.

Gravity is pushing the plane down, it has to move pretty fast to get enough lift to go anywhere. With the inability to move forward because of a conveyor countering the forward motion of the wheels, physics says the plane stays grounded. It's not my guess or opinion. This is physics.

 

No, because the friction coefficient between the fuselage and runway would be too great for the engines to overcome. Hence, the wheel which is the centerpoint for gravity forces against the airframe to meet the runway on a small contact patch. This gives planes the ability to take off. A moving runway opposite the planes take-off trajectory will only spin the wheels 2x faster than the planes speed. However, the thrust of the engines will still push the airframe against that small friction up the conveyor to take-off speeds.


edit: you keep editing so I have to keep updating this. First, gravity is pulling the plane down. Atmospheric pressure is pushing the plane down. You're thinking of physics involving power to the wheels. The wheels on a plane have no use other than to suspend the fuselage off the ground, reduced friction upon take-off, and make landing easier.
