Title: Will it Take Off?
Post by: Langanobob on November 27, 2011, 05:34:13 PM
I must have too much time on my hands at the end of a four day holiday.  With all due respects to Johnny Organ Donor I'm going to re-post this on the DMF, I don't think it was ever posted here:

A plane is standing on a runway that can move (some sort of conveyer belt). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in the opposite direction). Can the plane take off?"

Yes it will take off, and the reason why is because the airplane's wheels just roll free, the propeller is what makes the plane go therefore, the plane will take off regardless.

Post by: RAT900 on November 27, 2011, 11:10:04 PM
the thrust of the engine will move the plane forward getting the leading edge of the wing to lift-off speed

irrespective of what the wheels are doing or how fast they are spinning due to any opposing speed conveyor belt

the critical relationship is between the airframe, the engine creating thrust and the air

did someone have a problem wrapping their brain around that?

Because lord knows I want to stay away.

*sigh*

What causes planes to fly? Lift. How do we get lift? Airflow over/around wing (and/or any other "lifting surface") surfaces. What does a convener belt not provide, no matter how much thrust is applied to the airframe?

regardless of how fast the conveyor belt is moving, the plane will not stay on it.  The propeller or jet is pushing against the ambient air, not the speed of the belt.  The wheels rotate freely.  Once the plane is free of the belt, which may take a little longer than rolling away from a surface that is stationary, if there is enough room, it will roll forward and take off normally.

We're still trying to forget the pipemod.

I was intentionally not going down the pipemod road.  [roll]

Besides, IZ probably packed up again to move and can't find his pipe anymore.  And since he recently had "issues" with his computer, I'm sure the pictures can't be found either.

Both an absolute blessing.
