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]
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. Moderate aspect ratio: general-purpose wing, very widely used, for example on the Douglas DC-3 transport. High aspect ratio: long and slender wing. More efficient aerodynamically, having less ...
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.)
The natural outcome of this requirement is a wing design that is thin and wide, which has a low thickness-to-chord ratio. At lower speeds, undesirable parasitic drag is largely a function of the total surface area, which suggests using a wing with minimum chord, leading to the high aspect ratios seen on light aircraft and regional airliners ...
Aspect ratio (aeronautics) – 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. [23]
This tends to increase the lift-induced drag of the foreplane, which may be given a high aspect ratio in order to limit drag. [33] Such a canard airfoil has a greater airfoil camber than the wing. Another possibility is to decrease the aspect ratio of the canard, [34] with again more lift-induced drag and possibly a higher stall angle than the ...
The ratio of the length of a nose cone compared to its base diameter is known as the fineness ratio. This is sometimes also called the aspect ratio, though that term is usually applied to wings and tails. Fineness ratio is often applied to the entire vehicle, considering the overall length and diameter.
Pixel aspect ratio; Photolithography: the aspect ratio of an etched, or deposited structure is the ratio of the height of its vertical side wall to its width. HARMST High Aspect Ratios allow the construction of tall microstructures without slant; Tire code; Tire sizing; Turbocharger impeller sizing; Wing aspect ratio of an aircraft or bird
