The gull wing, also known as Polish wing or Puławski wing, is an aircraft wing configuration with a prominent bend in the wing inner section towards the wing root. Its name is derived from the seabirds which it resembles and from the Polish aircraft designer Zygmunt Puławski who started using this design in his planes.
Inverted gull wing: anhedral on the root section, dihedral on the main section. The opposite of a gull wing. May be used to reduce the length of wing-mounted undercarriage legs while allowing a raised fuselage, as on the German Junkers Ju 87 Stuka dive bomber. Cranked or canted tip: tip section dihedral differs from the main wing.
The wing was redesigned with slightly increased span, taken from the PZL P.8, and shorter ailerons were used, and structural changes eliminated external ribs from the wing upper surfaces. [1] P.7a production began in mid-1932 and the last of the 149 (plus two prototypes) were completed in 1933. [1] The Polish Air Force received the P.7a in 1933.
The aircraft was marketed in the United States as the Royal Gull by American distributor Kearney and Trecker. During the late 1950s, a land-based utility aircraft , the Piaggio P.166 , was developed from the P.136 and shares many design similarities, despite the deletion of the hull in favour of a conventional fuselage.
It was designed with a small amount of inverted gull wing bend; the inner sections had a 1° anhedral, while the outer sections, attached just outboard of the undercarriage legs, had a dihedral of 5 + 1 ⁄ 2 °. [10] The airfoil was a NACA 22 wing section, with a thickness-to-chord ratio of 19.5% at the root tapering to 12% at the tip. [19]
