| Till the internet explodes... and the plane takes off... |
I guess that must be a picture of you in your avatar? I can't blame you for not knowing shit about airplanes since you have never seen one, having wandered the jungle in a loincloth your entire life.

You have to realize that the conveyor belt is only acting on the plane's free-spinning wheels, which are not what powers a plane. The conveyor belt will have no effect on the plane engines' ability to move the plane forward. |
let's say the coneyor belt is moving 500mph, the plane produces enough thrust to move 500mph. It's going 500mph in relation to the conveyor belt, but not moving in relation to it's surroundings. Doesn't it need airspeed to provide lift under it's wings, or am I just living up to my avatar

It needs to have air moving over and below the wings to produce a difference in air pressure to generate lift. If the conveyor belt can somehow make the air move fast enough over the lift surfaces it will fly, if not it won't do shit. If it's pointed up at the sky with solid booster rockets like the space shuttle it won't matter because it isn't dependant on the wings for lift, it's a damn missile. |
No, it'll move 500 mph in relation to its surroundings, and 1000 mph in relation to the conveyor belt. Put on rollerskates, get on a treadmill. Put the treadmill at 10 mph, then skate at 10 mph. Not moving, right? Because you're using the interaction between your skates and the treadmill to move. This is why the treadmill vs. car works. Now attach a rope to the wall, and pull yourself forward at 10 mph. You will move forward at 10 mph, but your skates' wheels will rotate at 20 mph because treadmill is going back at 10. This is why treadmill vs. plane does not work. You're pulling on something independent of the treadmill in order to achieve forward motion, just like an aircraft. All your skates are doing is countering gravity and rotating freely. |
Is the plane attached to the belt or is it just sitting there? No air over the wings to produce lift, no fly, same with sails on boats. (no wind around the sail no move) Somehow you got to get the air flowing over one side faster then the other to induce lift. |
No shit. The belt does impart backwards force. But the plane/engine on has to generate enough force to break to start turning the wheels (this force is equal even if the belt is moveing 10mph as it is if the belt is moving 500mph). Beyond that point any excess force will move the plane forward, thus air over and under the wings, and you get lift. |
your right, the airplane is pulling the air to keep up with the treadmill, thus providing lift...in that case, it might fly
