The SZD-11 Albatros was a single-seat glider aircraft that was designed and built in Poland at Szybowcowy Zakład Doświadczalny - Glider Experimental Works in Bielsko-Biała in 1954. Only one prototype was completed and flown.
Development
[edit]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 main designer was Justyn Sandauer, and the main constructor was J. Niespał.[1] With wings of greater span, and reduced empty weight, the wing loading was reduced, markedly improving the climb performance over the 16m-span SZD-8 Jaskółka. Three more SZD-11 aircraft were planned with fixed trailing edges and no flaps, but only the prototype was completed. The SZD-11 first flew on 14 September 1954, flown by Tadeusz Góra.[1]
