Augusto Ulderico Cicaré (born May 25, 1937) is an Argentinian inventor, engineer and aviation designer. At the age of 11, still in 5th grade, he built his first four stroke engine that he used to drive a washing machine. In this same period he converted the engine of a car to use propane gas instead of petrol. By age 15 he was constructing motorcycle engines. Cicaré continues to be active in aviation design, his recent work including the Cicaré CH-10 and ultralight helicopters, and the development of the flight simulator, which was declared Argentina's national invention of the year in 1998.
