Sarnie Posted November 23, 2006 Share Posted November 23, 2006 Yes the plane will take off, but its wheels will be moving twice as fast! A plane needs to be moving forward to take off. On that conveyor belt it would be static Quote Link to comment Share on other sites More sharing options...
SwissZ Posted November 23, 2006 Share Posted November 23, 2006 Yes the plane will take off, but its wheels will be moving twice as fast! A plane needs to be moving forward to take off. On that conveyor belt it would be static Only if the power was coming from the wheels. Its the jet engines that are moving the plane forward, not the wheels. (granted, the wheels would be spinning seriously quickly) If you put a plane on sheet ice with the brakes hard on and turned the jets on it would still move forwards even though the wheels were stationary. No idea if it could get off the ground but it would move forwards because of the jet power giving you air flow and lift. The conveyor belt would just make the wheels turn backwards whilst the plane was being jet powered down the runway conveyor belt thing. My vote's a yes .

But if you bring into account that the engines pushing the plane forward on the conveyor belt then the wheels would be going round faster. If the wheels go round faster the conveyor belt would speed up neutralising the forward motion of the plane hence rendering the plane static. Therefore: NO LIFT Quote Link to comment Share on other sites More sharing options...

stevie_350z Posted November 23, 2006 Share Posted November 23, 2006 The whole problem with that question is the miracle operation of the conveyer belt, how it is somehow connected to the jumbo's wheels like gears. As that is true I suppose the jumbo wouldnae take off... Quote Link to comment Share on other sites More sharing options...

WoREoD Posted November 23, 2006 Share Posted November 23, 2006 Surely ("don't call me Shirley") the conveyor belt cant stop the plane from moving forward. The only contact point is the plane's wheels which aren't driven. The plane will move forward and take off. The conveyor belt cant stop it.... Can it?

The YES camp are presuming that the moving escalator can cause enough friction on the free-moving wheels to push pack the plane against the four Trent engines - hardly likely but since when are these type of questions realistic... even though us NO camp dudes know that the wheels on a plane could be doing anything without an effect on the plane - the bloody things could be going backwards for all the plane cares.

captint Posted November 23, 2006 Share Posted November 23, 2006 No quite simply, as soon as the plane would attempt to leave the belt, it would lose momentum and drop down, no under current to hold it up Quote Link to comment Share on other sites More sharing options...

sl114 Posted November 24, 2006 Share Posted November 24, 2006 Aircraft wheels are free spinning and the thrust will propell the aircraft forward wheels on the belt or not. If you could move the air around it in reverse then no it would not take off however just by moving the wheels will have no effect as its all to do with the thrust and air movement not ground movement. So its a trick question Quote Link to comment Share on other sites More sharing options...
Chesterfield Posted November 24, 2006 Share Posted November 24, 2006 It will take off. The converyor cant stop it, all that would happen is that the plane would move forward, and the converyor would speed up. The plane would continue to push forward and the conveyor would try and push it backward, but it wouldnt as the conveyor would just be spinning the wheels. The plane would eventually build up enough forward momentum and take off. Though it would need to be a VERY long runway and the wheels would be spinning at an infinite speed. It probably wouldnt take off in reality as the friction/heat built up in the wheels spinning at this rate would melt the tyres, cause the plane to list and wobble out of control, smash its lnding gear and end up a big messy fireball at the side of the conveyor.

stevie_350z Posted November 24, 2006 Share Posted November 24, 2006 Hopefully the conveyor would be one of those bouncy ones that you find in airports, so the plane could bounce to try and achieve lift off... the passengers would have to jump up and down at the same time, of course...
