| 410132 | 2006-02-02 00:59:00 | The only thing that will stop this plane from taking off is possibly the high amount of inertia on the wheels, causing them to become unstable, and perhaps break. That is bollocks too, there is no inertia involved at all. The wheels will rotate at a maximum of 2x lift-off speed, and that will only be for a few seconds. I'd be surprised if they couldn't handle that, because planes land at speeds above lift-off velocity, and sometimes considerably higher in adverse conditions. The wheels and tyres absorb the shock of contact at that speed (while stationary) no problem at all. Time to give this thread a rest. Cheers Billy 8-{) :groan: |

| 410134 | 2006-02-02 05:38:00 | Alright here it is. Imagine a plane is sat on the beginning of a massive conveyor belt/travelator type arrangement, as wide and as long as a runway, and intends to take off. The conveyer belt is designed to exactly match the speed of the wheels at any given time, moving in the opposite direction of rotation. There is no wind. Can the plane take off? Discuss....Of course it will.. The conveyer belt is designed to exactly match the speed of the wheels at any given time, moving in the opposite direction of rotation.the faster the wheels go, the faster the belt goes in the opposite direction.. so since the wheels will go clockwise (as airspeed builds) the conveyor goes anticlockwise.. making the wheels go faster but in no way affecting the thrust |

| 410140 | 2006-02-04 22:28:00 | Imagine that a sparrow is sitting on the beginning of a massive conveyor belt/travelator type arrangement, as wide and as long as a runway, and intends to take off. Through the miracles of modern opto-electronics, the conveyer belt is able to exactly match the speed of the bird's feet at any given time, moving in the opposite direction of the bird's forward movement. There is no wind. 1) Can the bird fly away? 2) If your opinion differs to that expressed for the airplane example, explain why that is so. Cheers Billy 8-{) :D |

| 410141 | 2006-02-05 00:12:00 | 10 No. 2) I covered the surface of the conveyor belt with fast acting glue. The sparrow is just chirping in frustration. Until my falcon comes for lunch. |
