the wheels must spin for acceleration to take place until sufficient speed is generated and lift occurs. the reason they "must" spin is because if they didn"t the plane would drag across the ground and friction would prevent it from ever getting enough speed to take off. anyway, i"ve been...

It does affect it, in proportions though. And to clarify on the wheels, the HARDER wheels will coast FARTHER than softer. Harder wheels have LESS rolling resistance than soft ones. The soft wheels under pressure will create a bigger ?footprint? on the surface. That larger footprint means more...

i"ll buy it.

Because freerolling wheels are not effected by ordinary conveyor belts. You"d need to have the conveyor belt going like mach 5 to keep the plane from going forward 100mph. The friction is that off.

Wrong wrong wrong wrong. Quit bullshitting us with your crap. It is not wise to tip the vessel of knowledge. Ed Grubberman, you fail to grasp Ti Kwan Leep, aproach me so that you may see ... BOOT TO THE HEAD !

is there a difference between "pulling" air and "pushing" via jet propulsion? i would imagine at low speeds propeller powered planes, which tend to sit on a tripod set of wheels with the nose pointed upward, would do nothing but spin the wheels. As the plane picks up speed and just before it...

how is this tricky at all? it"s exactly the same as a car on a dyno. the plane won"t do shit; no fancy physics needed. air isn"t moving over the wings so there is no lift. the wheels will spin and that"s it. this would not be a fun environment to hang around in as the gusts generated by the...
