Santos-Dumont No 19 Low-poly 3D model

Santos-Dumont No. 19, which was built to attempt to win the Grand Prix d'Aviation offered for a one kilometre closed-circuit flight. Powered by a 15 kW (20 hp) air-cooled Dutheil & Chalmers flat-twin engine mounted on the leading edge of the wing, it had a wingspan of 5.1 m. (16 ft 9 in), was 8 m (26 ft 3 in) long and weighed only 56 kg (123 lb) including fuel. It had a pair of hexagonal rudders below the wing on either side of the pilot, a forward mounted hexagonal elevator in front of the pilot and a cruciform tail which, like the boxkite-style canard surfaces on the earlier 14-bis biplane of 1906, pivoted on a universal joint to function both as elevator and rudder mounted at the end of a substantial single boom. There was no provision for lateral control. The undercarriage consisted of a pair of wheels in front of the pilot and a third behind, supplemented by a tailskid.
