Dubois-Rioux
In 1912 Dubois and Rioux designed a machine meant to fly at 140 kmh and also to hover: they described it as an "invulnerable war machine." A very handsome as well as ambitious ornithopter, it was unsuccessful like all its predecessors - and its successors so far. The frame was all-metal, fabric-covered. A long narrow tailplane and elevator were mounted on the top of the rear fuselage, whic had a long nearly cylindrical shape; the rudder was set below the elevator. The wings had flexible tips and trailing edges, and were actuated by a 35 hp Viale mounted backwards at the nose. A large inertial wheel was to regulate the flapping movements.
