Structurally and aerodynamically more efficient than a constant chord wing, and easier to make than the elliptical type. Trapezoidal: a tapered wing with straight leading and trailing edges: may be unswept or swept. [13] [14] [15] The straight tapered wing is one of the most common wing planforms, as seen on the Messerschmitt Bf 109. Inverse or ...
An elliptical wing is a wing planform whose leading and trailing edges each approximate two segments of an ellipse. It is not to be confused with annular wings , which may be elliptically shaped. Relatively few aircraft have adopted the elliptical wing, an even-smaller number of which attained mass production ; the majority of aircraft that did ...
Lifting line theory supposes wings that are long and thin with negligible fuselage, akin to a thin bar (the eponymous "lifting line") of span 2s driven through the fluid. . From the Kutta–Joukowski theorem, the lift L(y) on a 2-dimensional segment of the wing at distance y from the fuselage is proportional to the circulation Γ(y) about the bar a
(If a wing has a rectangular planform, rather than tapered or swept, then the chord is simply the width of the wing measured in the direction of airflow.) The term chord is also applied to the width of wing flaps, ailerons and rudder on an aircraft. Many wings are not rectangular, so they have different chords at different positions.
Trapezoidal planform. In aeronautics, a trapezoidal wing is a straight-edged and tapered wing planform.It may have any aspect ratio and may or may not be swept. [1] [2] [3]The thin, unswept, short-span, low-aspect-ratio trapezoidal configuration offers some advantages for high-speed flight and has been used on a small number of aircraft types.
The introduction of swept wings took place during a move to more highly tapered designs as well. Although it had long been known that an elliptical planform is "perfect" from an induced drag standpoint, it was also noticed that a linear taper of the wing had much the same effect, while being lighter.
