Excerpt: The B-1 GIL was the first Polish experimental helicopter, designed and constructed in 1950. The helicopter was designed at the research institute Gwny Instytut Lotnictwa - Main Aviation Institute in Warsaw, from an initiative of Zbigniew Brzoska. The Polish aviation industry was destroyed after World War II, and in addition, the principal of the Institute was the only person who had seen a helicopter (Sikorsky R-4 in England). Despite severe material shortages, work on the experimental design started in 1948, and the main designer became Bronisaw urakowski (brother of test pilot Janusz urakowski), who designed the helicopter rotor and the control system. It used simpler Hiller rotor type, with two auxiliary blades. The structure of the fuselage, tail boom, auxiliary rotor and tricycle undercarriage were designed by Tadeusz Chyliski. The power unit and final drive were designed by Zbigniew Brzoska. The design utilized some components left by the Germans, like a piston engine Hirth HM 504 (configured for vertical use) and wheels from a glider's landing gear. Initially, the helicopter had no name. It only received the registration SP-GIL, from the Institute abbreviation, and soon it became known as GIL (gil also means bullfinch in Polish). Later it was also given the designation B-1, from urakowski's initials. B-1 GIL Designers B-1 GIL (1951) Z.Brzoska, T.Chyliski, B.urakowskiThe helicopter was completed by the end of 1949.
