Trapezoidal wing

A trapezoidal wing is a straight-edged and tapered wing planform. It may have any aspect ratio and may or may not be swept.

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. In this wing configuration the leading edge sweeps back and the trailing edge sweeps forward. It can provide low aerodynamic drag at high speeds, while maintaining high strength and stiffness, and was used successfully during the early days of supersonic aircraft.
