Blaicher B-38

The Blaicher B-38 was a Polish, single seat sailplane completed in 1938. Notable for its use of long span Fowler flaps, its development was ended by the German invasion of Poland in September 1939.

Czerwinski CW 8

The Czerwinski CW 8 was a mid-1930s Polish open-frame basic training glider. Its design was advanced and its price low, but its stalling characteristics were too dangerous for beginners, so the thirty-plus examples completed were rapidly withdrawn from use. Two were subsequently modified, one with greater span and the other with a small engine.

Elzanowski ZE-1 Cytrynka

The Cytrynka was the last and most successful of three gliders designed and built by the youthful Start Aviation Circle in Warsaw. Elzanowski developed its design between 1929 and 1930. Constructed in the Circles workshop, it was funded by the Warsaw Aeroclub. It was a high wing monoplane with a two part, rectangular plan wing, built around two spars and largely fabric covered apart from a plywood covered leading edge. Aft of the wing trailing edge the fuselage was an open Warren girder, stiffened by wire bracing from the wings, but the forward part was a rectangular-section plywood struct ...

W.W.S.2 Zaba

Czerwinski improved the design of the CWJ-bis, with reduced structure weight and changes to the flying control surfaces, to improve performance and manoeuvrability. The W.W.S. 2 followed the primary trainer concept with a skeletal fuselage wire-braced to a simple fabric covered wing, supported by two struts each side, and tail unit. The completely open seating area followed the theory of the day, that called for the student pilot to feel the wind on his/her body to fully appreciate the movements of the aircraft in response to control movements and atmospheric changes, such as gusts, turbul ...

W.W.S.3 Delfin

To provide a higher performance glider, to complement the W.W.S.1 Salamandra and W.W.S.2 Zaba, Waclaw Czerwinski designed an all wood glider with smooth lines derived from wind tunnel tests at the Lwow Technical University. With a stiff structure optimised for higher speeds the W.W.S.3 had pleasant flying characteristics. The first prototype was built with two alternative tailplanes, one conventional with separate elevator, the other an all-flying surface, both of which were evaluated in airworthiness trials at the I.B.T.L. Instytut Badan Technicznych Lotnictwa – Institute of Aviation Tech ...

Warsztaty Szybowcowe Orlik

The Warsztaty Szybowcowe Orlik, also known as the Kocjan Orlik after the designer, is a family of Polish gull winged gliders that was designed by Antoni Kocjan and produced by Warsztaty Szybowcowe.

Warsztaty Szybowcowe Sokol

The Warsztaty Szybowcowe Sokol was a 1930s Polish aerobatic sailplane. Ten were built and flown by Polish aeroclubs, participating in national and international events, until the outbreak of the Second World War.
