December 19, 200520 yr comment_90187 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 Report
December 19, 200520 yr Author comment_90189 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...... Report
December 19, 200520 yr comment_90190 "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? Edited December 19, 200520 yr by Jason Report
December 19, 200520 yr Author comment_90191 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? Report
December 19, 200520 yr comment_90193 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. Report
December 19, 200520 yr comment_90196 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, 200520 yr by Jason Report
December 19, 200520 yr Author comment_90200 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? Report
December 19, 200520 yr comment_90202 The wheels do nothing aside from hold the plane off the ground Report
December 19, 200520 yr comment_90203 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.

December 19, 200520 yr Author comment_90205 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. Report
December 19, 200520 yr comment_90206 ok. it goes foward. the wheel enble the plane to move at low speeds and idle around the run way Edited December 19, 200520 yr by Jason Report
December 19, 200520 yr comment_90207 isnt this the same as riding a bike on a treadmill? but if the wheels stay still, the plane dosnt move... Report
December 19, 200520 yr comment_90208 It's not the same as a bike, as a planes wheels have no drive Report
December 19, 200520 yr Author comment_90209 no its different from a treadmill THINK about how the engines move the plane!!! :D Report
