caption_attribution_description: Brazilian aviation pioneer Alberto Santos-Dumont with his No. 18 "floatplane", never completed
context_page_description: Through his career, aviation pioneer Alberto Santos-Dumont designed, built, and demonstrated a variety of types of aircraft—balloons, airships, monoplanes, biplanes, and a helicopter.
context_section_description: No. 15 (aeroplane) – Tractor configuration biplane, powered by a 50 hp Antoinette engine mounted above the upper wing. High aspect ratio wings spanning 11 m with a chord of only 60 cm (2.0 ft), giving a surface area of 13 m², divided into three bays by full-chord vertical surfaces. Pronounced dihedral like the 14bis, fitted with mid-gap ailerons in front of the wings. The wings were skinned with 3 mm Okoume plywood. Undercarriage consisted of a single wheel mounted at the junction of the forward lower wing spars and a tailskid. Biplane tail carried on a pair of bamboo booms placed one above the other and laterally braced to the wings by steel cables. Damaged during taxying trials on 27 March 1907,: subsequently repaired and fitted with a 100 Antoinette V-16, but never flown successfully.
  No. 16 (hybrid airship) – 21 m long, 3 m diameter: capacity 99 m³. Fitted with a forward-mounted hexagonal elevator and a central 4 m span rectangular lifting surface, this was a hybrid airship incapable of flight relying solely on aerostatic buoyancy, instead requiring aerodynamic lift to fly. Tested unsuccessfully on 8 July 1907.
  No. 17
  No. 18 – Not an aircraft, but a propeller-driven "hydro-flotteur" powered by V-16 Antoinette engine driving a three-bladed propeller, and resting on an elongated central float stabilised by smaller floats either side.
  No. 19 Demoiselle
