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 wing can be mounted to the fuselage in high, low and middle positions. The wing design depends on many parameters such as selection of aspect ratio, taper ratio, sweepback angle, thickness ratio, section profile, washout and dihedral. [31] The cross-sectional shape of the wing is its airfoil. [32] The construction of the wing starts with ...
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 ...
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 wing. [35] A design approach used by Burt Rutan is a high aspect ratio canard with higher lift coefficient (the wing loading of the canard is between 1.6 and 2 times the wing one) and a canard ...
Relying partly on electric power might reduce specific fuel consumption (SFC) compared to a standard turbine-only design (turbofan or lower-consumption turboprops). SUGAR Volt is designed with a long, braced, high aspect ratio wing that decreases induced drag due to lift. The wings of SUGAR Volt would enable it to take off in a shorter distance ...
Planform view of a 787-9 showing its 9.6 wing aspect ratio and 32° wing sweep Front view of a Vietnam Airlines 787-10, the fuselage is 19 ft (5.8 m) wide and 19 + 1 ⁄ 2 ft (5.94 m) high while the fan has a 9.3 ft (2.8 m) diameter
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.)
