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.
The Schleicher Condor, also referred to as the Dittmar Condor, is a series of German high-wing, single and two-seat, gull winged, gliders that were designed by Heini Dittmar in the 1930s, produced in small quantities before the Second World War, produced again between 1952 and 1955 by Alexander Schleicher GmbH & Co and also by Ferdinand Schmetz.
The general layout of the glider was inspired by the Lippisch Fafnir II. [1] [2] The Zanonia is an all-wood design, with a mid-gull wing. Take-off is performed from a dolly and landing is on a fixed skid. Only one was built and it is registered as an amateur-built. [1] [2] [3]
Flight trials of the Gull 4 began in late 1947 revealing no major vices and very similar, if not superior, handling to the Olympia. Performance was superior, a measured L/D ratio of 24.2:1 compared very favourably with the Olympia's L/D ratio of 22.5:1, and minimum sink speeds were similar.
The 1938 Spalinger S.21 is one of a series of gull-winged gliders designed by Jakob Spalinger which began in 1934 with the S.15 and included the 1936 Spalinger S.18 which competed in that year's Berlin Olympic Games and dominated Swiss competitions and national records. [1] The heavier, two-seat S.21 has a wing increased in span by 23% and ...
The 1930 S.15 led to Jakob Spalinger's long series of wooden, gull wing gliders. The earlier versions of the type are not well recorded but all had high wings with rectangular inner panels, tapered outer panels and pairs of single external bracing struts.
The 14.0 m (45.9 ft) span wing is a gulled design, employing a Goettingen 535 airfoil, with air brakes for glidepath control. The structure is stressed for aerobatics at +/-12g. [1] [3] The Moswey III was constructed by building the fuselage around a large tube, which was then removed after construction. [1]
The Ibex was designed by Hall to investigate the reduced wetted area of the pod and boom configuration, hands off spiral stability of a gull wing, and the low speed performance of wide NACA slotted flaps. It also features a V tail, 135 lb (61 kg) of water ballast and a 15 m (49.2 ft) wingspan to comply with FAI Standard Class rules. [3]
