If it's running in the correct direction to keep the plane in the same spot relative to the unmoving ground then no, it won't take off. An airfoil needs air moving across it to generate lift. This air movement is generated by the engine thrust moving the plane (well the wing part of it anyway) through the air mass. If the airplane is standing still relative to the surrounding air mass then it will stay firmly planted on the belt no matter how much thrust it generates ... assuming the belt is capable of moving fast enough to match the forward thrust generated by the engines ... and assuming that there's not a hurricane in the area ... or a really, really big fan at the front of the treadmill. |
