Airplane on a Conveyor conundrum

Obviously It Worked .

One would still wonder whether both speeds were equal, however.

[white akita]

the speed of the conveyor belt is irrelevant once the plane starts to move.

Yup, but whether your measuring airspeed, ground speed or whatever, if both speeds are equal that plane should never be able to reach the point where it can gather any lift, and that is the only time at which the movement of the belt would become irrelevant.

some people just cant get their head round this and probably never will.

The record is within reach Matt.

Give a scientific explanation with irrefutable proof, not some back street huckleberry demonstration, and I'll take it as the gospel itself.

About another twelve pages or so to go, isn't there?

[white akita]

its that simple it shouldnt need explaining

[Dodge]

Yep, it will take off, it's been explained better than I could by others on here.

The speed needed for take of is generated by the thrust from the engines, how fast the wheels turn is irrelevant, small wheels/big wheels they just turn at different speeds for a given air speed. Think sea plane, no wheels, or a plane with wheels in ice.

Oh and when it reaches the end of the conveyor belt, and it beeps: £102mil . . . pray you have your club card!

Well, can I throw it back at you and all the nay-sayers (and I've asked this before, but no-one has managed to answer it)... give a scientific explanation how a conveyor belt, acting solely through a set of free spinning wheels, is able to excerpt any force upon the airframe of an aircraft that will prevent it from moving forward. The simple fact is that there is no way that that can happen. The conveyor cannot halt the forward progress of the aircraft, thus it achieves forward airspeed, and flight.

I (and others) have already given plenty of information as to how the aircraft will achieve flight. Also, the simple fact that the Mythbusters crew achieved flight must prove something. Whilst their methods might not have been scientifically rigorous, their success must prove that there is at least a serious flaw in all the arguments that say flight will not happen. Tell us where they went wrong, show us the fault in their methods, the flaw in their system!

never trust a ginger beardy thats the problem !!

Let it die! PLEASE!!!!

I'd rather see the same answers for the tenth time on the 'pop quiz' thread than go round and round with this old chestnut.

Oh, and by the way, I hate that tw*t from Mythbusters.
