Believe it or not, the Navy did look into this idea. Or a form of it.threeyardmiss wrote:If the plane does take off, then whats the big fuss about all these jet powered on the spot take off jets? Why dont they just bung a big conveyor belt on these war ships?
Will it take off ?!

Just imagine the runway is a moebius strip... a bit like this thread!

Well, in theory, airplanes don't need a conveyor belt to take off, just a normal runway will do...threeyardmiss wrote:So you dont need the conveyor belt at all? If its as long as the runway...Fuzzy Logic wrote:the conveyor belt still needs to be as long as the runway is.
as long as there's enough room to get up the necessary airspeed, bingo.
Can't believe this is still running

But Doug Ellis built a brick wall and DO'L taxied the plane until its nose butted against the wall. A new captain is being looked for but he may be put off by the current situation even if he can negotiate his way across the conveyor belt to get to the steps up.dead parrot wrote:this thread is probably still running because someone has likened Aston Villa to a plane attempting to take off while on an opposing conveyor belt?

you never read that post correctly!murf wrote:How did (s)he get a degree when (s)he incapable of reading a question correctly?Fido wrote:I asked my flatmate who has a degree in aviation. He said "There's no chance in hell it would take off".
Especially since there is no wind.
Fido asked her flatmate - she never said the flatmate read this question (or the other 16 pages of answers I'm guessing!)

Lift is generated by the vacuum created under the wing as the air is forced under the flap and so the pressure drops. When the flap moves then the air is routed and so provides lift. But if the plane is static then none of the weight has been reduced through kanetic enregy so requires VTOL engines like the Harrier has..

Aye but this plane isn't static. A fact the flat-earth society are still failing to grasp.theswinger wrote:Lift is generated by the vacuum created under the wing as the air is forced under the flap and so the pressure drops.

I'll come round later with my etch-a-sketch and prove it if you like

Already been done.AKNel1 wrote:Can somebody not forward this to Mythbusters or Brainiac
Mythbusters website has about 500 threads on the thing, with simple people asking the question again without bothering to look through the site and then being flamed for being idiotic and pointed in the right direction.
It DOES take off by the way, just incase anyone was still under the misguided impression it doesnt.
Worth a look if you have time, I did after this thread (actually towards the end as we were debating it). Dont know the link and cant be arsed looking, sorry.
Brainiac didnt get back to us, although we suspect that they have thousands of the same question and its not worth replying.

If I was standing on the wing of the plane (which I could do since the velocity of the plane and the runway cancel each other out) trying to fly a kite in no wind, would it fly?
If not, how could the plane?
OK, having probably demonstrated my complete ignorance of physics and aerodynamics in my only contribution to this thread, I'll wait to get flamed.

yep - the runway simply serves to hold the 'plane up on its wheels so that it can get up to take off velocity. Whether it's moving or not is irrelevant as the force pushing the plane forwards is the action of the jet engine, and nothing to do with the 'planes interaction with the runway. Once it clicks that a plane is not driven through its wheels, it should be a simple step to realise that the plane will take off (as long as the moving conveyor is as long as a standard runway)murf wrote:That is the incorrect assumption and the crux of the whole thing.....Raisin wrote:the velocity of the plane and the runway cancel each other out
