KE30Coupe Posted December 19, 2005 Report Share Posted December 19, 2005 The conveyer belt is designed to exactly match the speed of the wheels at any given time, moving in the opposite direction of rotation. This is the key line here, if the wheels are moving at 100kph -> and the conveyer belt is moving at 100kph <- the net effect is the wheels are not moving at all. In order to make the wheels move the plane needs foward thrust......therefore providing the plane provides enough foward thrust to develop the necessary pressures to get airbourne then it certainly will take off. The wheels however will be stationary. Or maybe I got it so totally wrong that I should be locked up :D Quote Link to comment Share on other sites More sharing options...
Mr Revhead[RL] Posted December 19, 2005 Author Report Share Posted December 19, 2005 remember guys: also for the purpose of this question it is assumed all engineering possibilities eg the belt is possible and jason, your on the wrong track..... think about how jet engines move a plane......

Jason Posted December 19, 2005 Report Share Posted December 19, 2005 (edited) "If its jets are going wouldn't they be thrusting the plane forward and therefore creating airflow over the wings, hence making the plane fly?" No, because the belt is compensating for the thrusting forward force. Ok, this is how I believe the jets power a plane. As they spin up, they exhaust faster air than they put in. Creating forward thrust. When a plane lines up to take off, the wheels act as kind of like 'back up wing' they don’t have anything to do with flying at all. As the engines create more thrust the planes gets faster until the point were the air resistance against the plane is great enough for the wings to do there thing (lift off). So as soon as it does, the wheels become useless. And then they jets continue powering the plane though out the flight. Right?

Mr Revhead[RL] Posted December 19, 2005 Author Report Share Posted December 19, 2005 No, becuse the belt is compensating for the thrusting foward force so your saying the belt is pushing against the plane hard enough to counter the engines force?

ancullen Posted December 19, 2005 Report Share Posted December 19, 2005 I stand by my second answer to this question: the plane will fly as it will be thrust forward by the engines. The conveyor belt will have the same effect as solid ground would have, that is, none aside from holding the plane up. Quote Link to comment Share on other sites More sharing options...
Jason Posted December 19, 2005 Report Share Posted December 19, 2005 (edited) The way I see it fly's because of wind resistance not because of the engine thrust, if that makes sence? Red engine thrust, green air resistance over plane as it goes forward.. well according to the question, the belt can go as fast as the wheels at any given time. So if there going 300km/h for take off (out of my ass figure) That means the belt is going -300km/h. 0 air speed, therfore no wind resitance. The plane can still go forwar realtive to its self, but from 3rd person its still 0 Edited December 19, 2005 by Jason Quote Link to comment Share on other sites More sharing options...
Mr Revhead[RL] Posted December 19, 2005 Author Report Share Posted December 19, 2005 ah... i think u lost me in there some where jason how can it move relative to itself, but not to a 3rd person? think again, what drives a plane forward? what do the wheels do on a plane?

Rolla__Boy Posted December 19, 2005 Report Share Posted December 19, 2005 The wheels do nothing aside from hold the plane off the ground Quote Link to comment Share on other sites More sharing options...
Jason Posted December 19, 2005 Report Share Posted December 19, 2005 (edited) well, the plane is regersting its moving 300km/h (my eg) but when you looking at it on the belt, its not moving at all. The wheel keep it moving until there enough speed to lift itself off the ground? Insted of having wheels and a belt, just have no wheels at all and make sure it can no go forward. will it still take off? The belt does nothing except keep the plane from moving.

Mr Revhead[RL] Posted December 19, 2005 Author Report Share Posted December 19, 2005 ok jason, your confused.... stop, start again. forget all youv thought of till now. think about how an engine moves a plane. think about what wheels or skids for that matter do on a plane. if an engines starts on a plane.. what happens.

Jason Posted December 19, 2005 Report Share Posted December 19, 2005 (edited) ok. it goes foward. the wheel enble the plane to move at low speeds and idle around the run way Edited December 19, 2005 by Jason Quote Link to comment Share on other sites More sharing options...
tom210 Posted December 19, 2005 Report Share Posted December 19, 2005 isnt this the same as riding a bike on a treadmill? but if the wheels stay still, the plane dosnt move... Quote Link to comment Share on other sites More sharing options...
Rolla__Boy Posted December 19, 2005 Report Share Posted December 19, 2005 It's not the same as a bike, as a planes wheels have no drive Quote Link to comment Share on other sites More sharing options...
Mr Revhead[RL] Posted December 19, 2005 Author Report Share Posted December 19, 2005 no its different from a treadmill THINK about how the engines move the plane!!! :D Quote Link to comment Share on other sites More sharing options...
