unusual facts about SZD-21 Kobuz


SZD-21 Kobuz

Development began in January 1958 as the SZD-21 Sokół, but due to problems with the flying surfaces and a wood metal sandwich, a construction of the design was restarted as the SZD-21 Kobuz (Eurasian Hobby).


SZD-11 Albatros

Based on a fuselage of the SZD-8 Jaskółka, the SZD-11 Albatros was designed to investigate the performance of aircraft during flight in thermal lift.

The SZD-11 first flew on 14 September 1954, flown by Tadeusz Góra.

SZD-14x Jaskółka M

The SZD-14X Jaskółka M was developed from the SZD-8bis Jaskółka (Swallow) for research into the construction, control and characteristics of 'V' or butterfly tail surfaces.

SZD-36 Cobra 15

The aircraft was designed especially for the 1970 World Gliding Championships at Marfa, Texas, where J. Wroblewski took 2nd and F. Kępka took 3rd places in the Standard Class behind a Rolladen-Schneider LS1.

SZD-40x Halny

This (flap) modification was a definite departure from previous (Zefir) attempts in variable wing geometry glider design.

Spurred on by the high performance two seaters emerging from the German Akafliegs, like the SB 10 Schiroko, SZD modified the SZD-37x Jantar fuselage to take two seats in tandem and fitted the wings developed from the Zefir 4 to make the SZD-40 Halny.

SZD-49 Jantar K

Władysław Okarmus set about designing a new wing, with flaps, for use with the SZD-48-3 fuselage, the resulting off-spring was named SZD-49 Jantar K. First flight of the prototype, (SP-2583, X-143), took place at Bielsko in October 1978.
