examples of wing shapes
From one era to the next and depending on the type of aircraft, the shape and position of the wings in relation to the fuselage has varied.
delta wing 
Thin triangular wing that is especially aerodynamic.
variable geometry wing 
Arrow-shaped wing found on combat aircraft; the angle it forms with the fuselage can be changed in flight.
tapered wing 
Wing that is perpendicular to the fuselage and whose width decreases toward the tip.
straight wing 
Long wing of consistent width and perpendicular to the fuselage; it is found on low-speed planes such as cargo and light planes.
swept-back wing 
Arrow-shaped wing that is found on jet planes.
