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 has a low aspect ratio. [1]
It featured broad chord, low aspect ratio swept wings, with twin wing-mounted tail fins either side of a short fuselage. There were no flaps. [4] The cockpit, which was pressurized, was situated well forward to provide good visibility for the pilot during aircraft carrier approaches. [1] The pilot was provisioned with an ejector seat. [4]
Low aspect ratio: short and stubby wing. Structurally efficient, high instantaneous roll rate, low supersonic drag. Structurally efficient, high instantaneous roll rate, low supersonic drag. They tend to be used on fighter aircraft, such as the Lockheed F-104 Starfighter , and on very high-speed aircraft including the North American X-15 .
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]
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.
A tall, fixed main undercarriage combined with a small tailwheel gave the aircraft a 22° "nose-high" angle. [4] Ground testing of the V-173. The disc wing design featured a low aspect ratio that overcame the built-in disadvantages of induced drag created at the wingtips with the large propellers actively canceling the drag-causing tip vortices ...

The aircraft is unusual in that it is a lifting body – the whole aircraft acts as a low aspect ratio wing: a flat, angular lifting shape, unlike traditional aircraft which use distinct lift-generating wings attached to a non-lifting fuselage.
