It is theoretically possible that a propeller driven aircraft with an abundance of power could throw enough propwash to generate a sufficient deflected slipstream against flaps and over elevator control surfaces creating enough lift for the aircraft to fly itself off the conveyor belt.

How long is the conveyor belt?

Just watched a mythbusters segment of that question, Their plane took off. So I'm going to say yes the plane can take off because mythbusters 'kind of" proved it.

Come on . . . seriously? This thread doesn't need to be revived.

Somebody please lock it and save us all the trouble.

This is a hypothetical, and hypothetically speaking such a magical conveyor cannot be replicated in real life. The instant the wheel would speed up, so would the conveyor, without any delay. The increase in speed would be so great and so rapid that the wheels would burst. But since this is a magical conveyor, with magical wheels, they won't, so now the friction becomes the only force really holding the aircraft back. Eventually it will become so great (due to the rapidly accelerating conveyor) that it will become enough of a rearward acting force to become at equilibrium with the forward force the engines are producing and hold the aircraft back from accelerating and gaining airspeed.

The question is:

Will the plane take off or not?

[Emphasis added]


The plane moves...


Therefore, the plane flies.
