context_page_description: The PWS-101 was a high performance Polish glider first flown in 1937. One made the longest distance glider flight in Europe in 1938, gathering prizes for aircraft and pilot.
context_section_description: Podlaska Wytwórnia Samolotów, generally known by its initials PWS, expanded into glider design and manufacture in 1936. Their first example, the PWS 101, was designed by Wacław Czerwiński who was a specialist glider designer, most recently of the 1934 CW 7 and CW 8. The PWS 101 was flown for the first time in the spring of 1937.
  The single-seat PWS-101 was an all wood sailplane with a high aspect ratio, mid-mounted, gull wing. The inner 40% part of the span had a dihedral of about 8° but the remainder had little. In plan the wings were straight-tapered, mostly on the trailing edge. Its two parts were each built around a single spar which formed the rear of a plywood D-box including the leading edge. The innermost 25% of the span was further reinforced with ply covering and the rest of the surface was fabric-covered. Divided ailerons occupied more than half the trailing edges. A DFS type air brake, mounted on the spar at about one-third span, could be extended both above and below the wing.
  Its fuselage was a ply-covered, oval section semi-monocoque structure with an enclosed, multi-transparency cockpit above the leading edges of the wing roots. Some of the production PWS-101s had 40 l (1.4 cu ft) water ballast tanks. The fuselage tapered smoothly aft to a conventional empennage with a straight-tapered tailplane mounted on top and a curved fin, both ply-covered. The control surfaces were fabric-covered; the rudder was large and rounded and the elevators were semi-elliptical and assisted with inboard Flettner tabs. The PWS-101 landed on a sprung skid.
