Aspect ratio (aeronautics) An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56) In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing ...
Wing configuration. The Spitfire wing may be classified as: "a conventional low-wing cantilever monoplane with unswept elliptical wings of moderate aspect ratio and slight dihedral". The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes) is its arrangement of lifting and related surfaces.
The ratio of the length (or span) of a rectangular-planform wing to its chord is known as the aspect ratio, an important indicator of the lift-induced drag the wing will create. [7] (For wings with planforms that are not rectangular, the aspect ratio is calculated as the square of the span divided by the wing planform area.)
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 ...
First flight. 29 September 1948. Retired. 2 March 1959. The Vought F7U Cutlass is a United States Navy carrier -based jet fighter and fighter-bomber designed and produced by the aircraft manufacturer Chance Vought. It was the first tailless production fighter in the United States as well as the Navy's first jet equipped with swept wings and the ...
A developed version of the original V-173 prototype, the XF5U-1 was a larger aircraft. Of all-metal construction, it was almost five times heavier, with two 1,400 hp (1,193 kW) Pratt & Whitney R-2000 radial engines. The configuration was designed to create a low aspect ratio aircraft with low takeoff and landing speeds but high top speed. [2]
For a given wing area, a high aspect ratio wing will produce less induced drag than a wing of low aspect ratio. [16] While induced drag is inversely proportional to the square of the wingspan, not necessarily inversely proportional to aspect ratio, if the wing area is held constant, then induced drag will be inversely proportional to aspect ...
The droop nose is a feature fitted to a small number of aircraft types so the nose of the aircraft can be lowered during takeoff and landing to improve the pilot's view of the ground below. This feature is used with a very-low aspect ratio wing such as a delta wing. It is installed in aircraft capable of supersonic speeds but is lowered only ...
