Excerpt: The Junak was a Polish trainer aircraft, used from 1952 to 1961 by the Polish Air Force and until 1972 by Polish civilian operators. It was designed in the LWD bureau and produced in the WSK factory. The aircraft was designed in response to a Polish Air Force requirement of 1946 for a trainer to replace the Soviet UT-2, which was obsolete. The new aircraft was designed in 1947 in the LWD (Lotnicze Warsztaty Dowiadczalne - Aircraft Experimental Workshops) - the first Polish post-war construction bureau. The chief designer was Tadeusz Sotyk. A prototype named the LWD Junak, later the Junak 1, was flown on February 22, 1948 (its name means "brave young man").

The plane's handling improved. The LWD team disbanded in 1950 and Junak 2 development was continued by the CSS workshops in Warsaw. After further improvements the prototype was designated the Junak-2bis, but finally entered production in 1951 as the Junak-2. Tadeusz Sotyk was given a State Award in 1952 for the design. From 1951 to 1954, 105 Junak 2s were produced in the WSK-Okcie in Warsaw (the first 3 in the WSK-Mielec). Tadeusz Sotyk, then working in the Aviation Institute (Instytut Lotnictwa - IL) in Warsaw, proposed a Junak deve...More: http://booksllc.net/?id=927185
