The surface area of the wing is slightly reduced, resulting in a reduced ability to generate lift. The effective aspect ratio is reduced, helping to increase wing tip vortices. Also, it is harder to recover from a stall with a swept wing aircraft, as the rear of the wing tends to stall first. This produces a greater nose up pitch on stalling, which is far harder to recover from than with a straight-winged aircraft.
reduced drag
"Swept back' just refers to the wing shape. It can be a commercial, private or military aircraft.
Delta wing is the swept back wing design seen on jet airplanes like the Concorde. It is also a race car used in Le Mans in 2012.
The F-22 Raptor possesses a trapezoidal wing configuration: a low aspect-ratio tapered wing wherein the leading edge is swept back, and the trailing edge swept forward to form somewhat of a diamond-shape.
A swept back wing reduces induced drag by allowing the wing to better distribute lift across its span. This helps to minimize the formation of turbulent wingtip vortices which contribute to induced drag. Additionally, the sweep angle reduces the effective angle of attack at the wingtips, which further reduces induced drag.
Wing shape means the shape of the wings, of which there are three main types. Straight, Swept-back and Delta. Straight wings are plain straight, and are stable, however, less aerodynamic. The Cessna Skywhawk is a good example. Swept-back is used on faster craft but sub-sonic and are used on craft such as the Boeing 737. The Delta wing is used for craft that fly above Mach 1, such as the Concorde or Space Shuttle.
1. swept back wings are contributes to more lateral stability, 2. swept back wings produce less lift, so in turbulent weather they are less susceptible to abrupt changes, 3. They are designed with low thickness and high fineness ratio, hence less form drag, 4. genarally they are tapered, so less induced drag, 5. Capable of flying at high mach no. as actual relative wind speed is at an angle to the wing leading surface and therefore the wind component perpendicular to the wing leading edge is less, and hence the wing senses less speed than actual. so they can fly to high mach no.'s. if a straight wing is changed into a swept back wing similar parameters of area,aspect ratio, taper,section and washout, the CL is reduced. this is due to premature flow separation from the upper surface at the wing tips. suppose sweep angle of 45 degree CL reduced 30%
It's considered a swept wing design.
The word swept is the past participle, past tense of the verb to sweep (He swept the floor.), and an adjective, a word that describes a noun (The plane had a swept wing.). There is no plural form for a verb or an adjective. Nouns and pronouns have plural forms.
Swept wings are preferred in supersonic aircraft to facilitate vertical take off and reduce runway length during take off.
The back of a bird's wing. :D
