Then from the equation for a trapezoid, the area is one half the sum of the tip and root chords times the semi-span; Other firms tried trapezoidal wings, or ones that approximated an ellipse with two or three trapezoidal panels, and found them not noticeably inferior to the elliptical.

To date, all major aircraft to use this design have come from the United States.

A trapezoidal wing is a straight-edged and tapered wing planform.It may have any aspect ratio and may or may not be swept.. 2.1 X-planes; 2.2 Military planes; 2.3 Civil planes; 3 See also; History.

The SKYLEADER 600 is an all metal two-seat, low wing constructed aircraft with a trapezoidal wing. The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes) is its arrangement of lifting and related surfaces.. Aircraft designs are often classified by their wing configuration.

Trapezoidal The trapezoidal wing is a high performance configuration such that the leading edge sweeps back and the trailing edge sweeps forward.

This wing configuration offers efficient supersonic flight and has very good stealth characteristics. ( delta wing , swept wing , swing wing ,Trapezoidal wing ) why aircraft like mig-25 , f-15 use swept wing in stead of delta design ( they are much faster than mirage , F-106 ) why the nose of space shuttle is not so sharp ( isn't it reduce more drag if it sharp :confused:) The trapezoidal wing area (842 m 2) is taken as the reference area for the aerodynamic coefficients and the mean chord (C ref = 12.3 m) is taken as reference chord for the pitching moment coefficient and the lift per unit of span definition. 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. F-104) Nose shape for the space shuttle was a trade of material (inconel, carbon/carbon, ceramic), weight, cost, durability. 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 rounded wingtip survived as a relic of the ideal ellipse until North American’s P-51 and Grumman’s F6F Hellcat abandoned even it. For example, the Supermarine Spitfire is a conventional low wing cantilever monoplane of straight elliptical planform with moderate aspect ratio and slight dihedral. The aircraft has a tricycle towed fixed landing gear with wheel pants and a steerable nose wheel, either retractable gear option. Flow about the NASA trapezoidal wing is computed with several turbulence models by using grids from the first high-lift prediction workshop in an effort to advance understanding of computational fluid dynamics modeling for this type of flowfield. The trapezoidal design allows for a thin wing with low drag at high speeds, while maintaining high strength and stiffness.

Transition is accounted for in many of the computations.

Especially when this wing is covered with sheet metal, it makes sense to have only one direction of curvature, thus trapezoidal planforms soon became the preferred way of building wings once aluminium became the primary structural material for aircraft.
