Vuitton-Huber No.1


First helicopter developed by the Vuitton-Huber firm around 1908 or 1909, first shown at the 1909 Paris Exposition without a motor. The two four-blade counter-rotating rotors were driven directly by the engine mounted on a four-wheel chassis. A small pusher-propeller was installed at the rear and outward of the pyramidal frame for horizontal thrust. Steering of the machine was achieved by the pilot's leaning, combined with a rudder in the tail area. A horizontal surface was installed forward of the machine for stability.
