would a plane take off if..
« on: January 07, 2010, 05:29:35 PM »
imagine a plane is sat on the beginning of a massive conveyor belt/travelator type arrangement, as wide and as long as a runway, and intends to take off. The conveyer belt is designed to exactly match the speed of the wheels at any given time, moving in the opposite direction of rotation.
There is no wind.

Can the plane take off?

Obviously he hasn't, they answered that one, all the while they were rolling their eyes.  It looked, and sounded like" we know the answer, smart people know the answer but we will do this myth for the less than intelligent."

No. No Airlift, if your going 70mph but no were, there is no air moving on the wings, thus not able to lift.

Ugh, someone please find this thread.  Yes, it flies because wheels on planes don't work like wheels on cars.  They are rolling backwards at whatever speed the conveyor belt is going, yet the plane moves forward because thrust is generated from somewhere other than the wheels. (the prop)  Therefore, the plane still picks up speed, still generates lift, and still takes off.  Again, the wheels can move in whatever direction they want -- it matters not.   :aok

Also, if this is bait, I'll take it.   :cheers:

It DOES fly, idiots...
The pegasus engines direct their thrust downward, the US Marine Corps pilot increases the thrust, and off they go.

Just saw this but I first thought no, there's no lift under the wings, since you aren't going anywhere.

It flies.  It doesn't accelerate because of the wheels, they just roll.  The prop/jet thrust accelerates the aircraft through the air and that isn't affected by any treadmill contraption.  All the treadmill would do is make the wheels spin faster as it took off.
