Best Tech. Debate: Groundspeed vs. airspeed

^ thats definatly the smart way to explain it. lol.

Substitue the word velocity for speed in everything ive said...

how are You getting drag but not lift?

You are thinking in velocity, not mass.

The lift is generated by the velocity of the air not the wing. It would lift up slowly gain forward momentum and then begin to fly naturally. Assuming powerful enough engines however.

By in part, this should help You all think about tuning enclosures //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif

The plane will take off like the runway wasn't moving. The prop provides forward thrust, not the wheels. The wheels are just dragged along passively.

exactly, but if there is no wind, and the velocity of the plane is 0(150mph forward while the conveyor is 150mph backwards), there is no wind velocity.

technically, the airfoil is what creates the lift from the wind velocty though. different airfoil designs can make more or less lift from the given wind velocity. Slowe planes, like ultralights, have a higher foil to slow down the air passing over the foil even more, making the overall lift greater. Compared to figter jets which have a Sleeker, more efficient air foil that creates less drag, since it dosent need such a great lift at low speeds.

either way, thats besides the point. No wind velocity = no lift.

No the engines draw air accross the wings. The Velocity of the air would be say 300mph. Thus lift.

i see what your saying. i dont really know how props work, so that could be possible...

The plane will fly.

The plane will fly.

agreed, the engine will pull the plane along because it acts on the air, the conveyor belt only affects the wheels

*edit* shit will fly and stuff, barfbag.

I was trying to avoid giving away the explaination of why //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

fine fine, edited.

Well if the engines are on, prop or jet, and the stupid runway just moves then of course it will fly.
