The wheels are independent of the plane you r-tards... they are not drive wheels... and have nothing to do with the lift of the plane...

well if the conveyor belt surface has enough friction to keep the wheels in place (relative to the conveyor belt) while the engine is theoretically moving the plane forward at the same speed the conveyor belt is moving backward then it still would not move correct?

It's like when your on a boat thats going one way while your walking the other way. Your moving, but your staying in the same spot.

so for those saying that it wont cause there is no lift....then you would also say that if you stopped the conveyor belt after it was moving to a speed equivalent of what a plane would usually take off....the plane should almost instantly be at full speed and in a perfect situation would take off instantly without having to move forward? like if you hold a ball in a car its speed relative to you is 0 but if you drop it the instant it hits the stationary ground it will try to accelerate to the speed of the car it was previously in?

Such feeble little minds...

I don't think they could get the conveyer belt to move that fast. But the ball couldn't move as fast because the instant you let it go it is subject to wind, friction, bounce, and probably other factors I have no idea of what they are.

I mean, I'm nowhere near a Aeronautics or Physics genius, not even a beginner really, but I'm just letting my thoughts float.

I like to double post.

when did i double post ngsm? I mean, I posted twice in a row, but they are two different posts...

Give up Konechiwa, it was already been discussed dozens of times, the friction caused by the conveyor belt spinning the wheels twice as fast is nothing compared to the thrust generated by the plane itself...

The plane can not lift off unless there is air moving past the wings. The wheels can move all **** day but if there is not enough wind speed to force the wings upward the plane will sit on the ground.

On the other end of the spectrum:

If you tied the plane to a pole and placed a huge, high speed fan in front of it the plane would lift off, yet not move forward, like a kite.

This is why they use a wind tunnel to test down force on race cars and not a dynomometer. //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

OK this is what would happen. The plan would move forward because the propeller will draw it forward. Even if the plane was totally off, with the brakes off, and the belt running, the body of the plane will largely remain stationary with only the wheels spinning.

So, if they turn the propeller on, no matter how fast the conveyer is going, it won't take off.

However, if the plane remains stationary, relative to the ground, it won't take off.

think of it this way, a hot wheels car with a spring, which will move as fast as the conveyer belt, and the car would fly if were to land on the table and fly off. But at the end take off theres pavement, but the plane is fast enough at this time and takes off. Not a conveyer belt would be ideal for something like a plane, but more like something that ataches to the plane and pushes it like the hotwheels car spring thingy.

yah your right. I kept thinking that the wheels would have the same ammount of thrust as the engine would (when they are on a conveyor belt).

I pwned myself //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I love how easy this simple question makes it to point out tards...
