Lucien Chauviere, a well-known propeller designer, built a machine dubbed the Gyroptere in 1927, based on the principles of a patent he had filed ten years earlier. It used a 170kW Renault engine to drive a four-blade rotor with flapping hinges and clutched to power a tractor propeller at the nose. To counter torque while the rotor was powered, control flaps mounted vertically on the fuselage sides vectored the slipstream. Testing of the 1,372kg aircraft did not progress very far before his available finances were expended. www.vtol.org
