1953-project  In 1952-1953 a study of a helicopter designated GIL-3 (where "GIL" stood for "Główny Instytut Lotnictwa" or "Main Aviation Institute") was prepared. It was to have an engine developing 870 shp (the type had not been specified) and its payload should have been around 800 kg. No further works were undertaken however and the design team led by Bronisaw urakowski concentrated on a single-rotor helicopter project, the GIL-4 that later became the B-4 uk. Petrus, SPF |
