NEIN | Actually a plane stays in the air because of the lift created when air traveling over the top of the wing is moving faster than the air traveling under the wing. The basics of flying. On a fixed wing plane the movement thru the air is created by the pull of the propeller with the slipstream pretty much being straight back from the front. On a rotor craft machine, ie a helicopter where the wings move, the lift is created by the air going over the rotor blades (wings), a combination of the wing and the propeller in one, and the slip stream is almost straight down, especially in a hover. How much difference there is when flying forward and is it enough to matter is another subject I suppose. | |
