The Gyroplane Laboratoire was an early helicopter. Its designer, Frenchman Louis Breguet, had already experimented with rotorcraft in 1909; however, he chose to concentrate on airplanes until the end of the 1920s. In 1929 he announced a set of patents which addressed the flight stabilization of rotorcraft, and, in 1931, Breguet created the Syndicat d'Etudes de Gyroplane (French for "Syndicate for Gyroplane Studies"), together with Rene Dorand as technical director. Their goal was the development of an experimental helicopter, the Gyroplane Laboratoire.
