The top view shows a simple wing geometry, like that found on a light general aviation aircraft. The front of the wing (at the bottom) is called the
leading edge; the back of the wing (at the top) is called the
trailing edge. The distance from the leading to trailing edges is called the
chord, denoted by the symbol
c. The ends of the wing are called the
wing tips, and the distance from one wing tip to the other is called the
span, given the symbol
s. The shape of the wing, when viewed from above looking down onto the wing, is called a
planform. In this figure, the planform is a rectangle. For a rectangular wing, the chord length at every location along the span is the same. For most
other planforms, the chord length varies along the span. The
wing area, A, is the projected area of the planform and is bounded by the leading and trailing edges and the wing tips.
Note:The wing area is NOT the total surface area of the wing. The total surface area includes both upper and lower surfaces. The wing area is a projected area and is almost half of the total surface area.
Смысл, естественно, такой же, как и в английском языке.
