دانلود جزوه Wing Structures aircraft
Wings were previously referred to as main planes; they produce the lift that supports the aircraft in flight. When air flows over the top surface of a wing from the leading edge [Le] to the trailing edge [Te] the distance that it has to travel is increased by the camber [curve] of the surface compared with the distance that it would have to travel when passing under the wing, as shown in diagram 3.1 above. The air flowing over the cambered surface increases its velocity, which results in a decrease in the static pressure above the wing. The amount of lift produced is dependent on the speed of the air over the wing, the camber and the surface area of the wing.
