    if you launched a 747 from a conveyer belt, and the belt was moving in reverse, would the plane take off ??

    i can't remember exactly how that question goes, well you get the idea right

    A plane is standing on a runway that can move (some sort of band conveyer). 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?

    Hey downhill,you mentioned about Mt. everest. Thank you for referencing Mt. everest. i'm proud to say that i from Nepal(Land of Mt. everest and Lord Buddha).
    thank you all for having me although i didn tget my required answer.
    From this discussion forum all i can expect is to get nonsense answer rather than helping me specially in Maths pro.

    This is a general discussion forum. If you wanted help with a math equation you should have gone to a math forum. WHOA! One of those light bulbs just burst over my head!


    Stick around and have a good time. You will see math is not something usually discussed as it doesn't have much to do with what goes on around here.

    so the plane is not really moving forward then,

    it's like walking on an escalator backwards at the same speed as the escaltor,you will stay in one place

    the plane needs wind over and under it moving to lift, does'nt it?

    I say no

    lol..here we go again. I think the last time this question was asked, the internet imploded, the [H]ardForum db shat on itself (again! haha), and Moses came down to part the land of SpeedGuide. The answer is yes, it takes off since the conveyor can't spin at infinite speed (I thought it was no as well, believe me, but I learned otherwise).

    See that's what I would think, the wheels would just spin under the plane, but it wouldn't actually go anywhere, it needs lift.

    But, if the plane is going forward, but the belt is going backward, what then? With this I woul say it WOULD fly, because the wheels do not act as thrust for the plane like it does for a car.

    but the wheels still need traction for the engines to make it move down the runway to get the lift?

    well theoretically if the engine is powerful enough you wouldn't need wheels at all, it'd be a bumpy ride, but as long as you can get the hunk of metal up to speed and create lift it'll fly

    the wheels on the plane don't act as thrust

    at least it makes sense in my head, i don't know if that is actually right, but kinda sounds logical eh?

    no sir, the wheels just roll -- the engines push the plane. think of it this way, the wheels spin normal speed on a normal runway -- the same speed as the plane is moving forward..now, put it on the conveyor and they move at that normal speed + the speed of the conveyor, but the plane moves the same speed..basically, the wheels just spin twice as fast (if the conveyor is matching the plane's speed, somehow). yea, yard's head is gonna implode, glhf, i'm going to sleep yea, al gore can be pissed from his private chartered jet as he helps melt the world...yea right.
