>>646597299 Once again, for the newfriend. 180kts, air speed, not ground speed you fucktard. In order for an aircraft to achieve lift, air must travel across the wing, whereby it moves slower as it travels over the top of the wing than underneath it, creating a differential of air pressure, thereby creating lift. A treadmill running the wheels at 180kts will not move the necessary wind speed over the wings to allow it to lift off the ground Duh. Don't be such an autist
>inb4 this is bait Some dumbass is going to believe this shit.
The point the video makes, is that the propeller/jet turbine move the plane independently of the wheels. A plane will always move forward on a conveyor belt running in the opposite direction, because the wheels just spin freely, they don't provide the forward thrust.
What's the difference between your car and a plane? A plane has wings. Your car doesn't. What typically causes a vehicle to leave flat ground? Lift. Wings cause lift. Your car doesn't have wings. A plane does. What makes wings create lift? It's wind resistance that pushes the plane up. A treadmill moves the ground underneath, but NOT the air above the ground. Wings NOT moving against wind cannot create lift. This means the fundamental feature, lift, the ONLY meaningful difference between a plane and your car is removed. Trying to get the PLANE to fly on a treadmill is identical to trying to get your CAR to fly on a treadmill. Of COURSE we can't get your car on a treadmill to fly, it has no lift. Of COURSE we can't get a plane on a treadmill to fly, it has no lift. You may as well take giant jacks, raise the plane off the runway, spin the tires, deactivate the propeller, and try to take off. On a treadmill, that's almost exactly what it's doing. The answer to this is obviously, no, a treadmilling plane cannot take off.
