Shoulder wing

An ARV Super2 with a shoulder-wing.

A shoulder wing (a category between high-wing and mid-wing) is a monoplane aircraft wing configuration in which the wing is mounted near the top of the fuselage, but not on the top.[1]

Shoulder wing designs include a wide range of aircraft from pre-World War II airliners, World War II bombers and strike aircraft, through Cold War fighters, civil and military transports to light aircraft and gliders.

Shoulder wing on light aircraft

The shoulder wing has particular advantages for smaller aircraft with a canopied cockpit, in that it gives the pilot unrestricted forward visibility, especially prior to and and during turns.[2] Optimally, the shoulder wing is put at the level of the pilot's eyes, to minimise any obstruction to visibility from the wing.[3]

On a light aircraft, a shoulder-wing may need to be swept forward to maintain CoG. A shoulder wing is like a high-wing, in producing a pendulous fuselage requiring no wing dihedral and its limited ground effect reduces float on landing.

History

In the 1920s the term "shoulder decker" was applied in Germany to note a monoplane where the wing was attached near the top longerons; the Junkers G.38 being an example.[4]
