|the Hydravion during tests in 1911.|
|Owners and operators||Henri Fabre|
|Fate||Crashed on 12 April 1911|
The Hydravion was developed over a period of four years by Fabre, assisted by a mechanic named Marius Burdin, (a former mechanic of Captain Ferdinand Ferber) and Léon Sebille, a naval architect from Marseilles.
The Hydravion was a canard configuration monoplane. The structure made extensive use of a beam design patented by Fabre. This was warren truss girder with all members of a streamlined section. Two of these beams, one above the other and connected by three substantial struts, formed the fuselage of the aircraft. The wing, which had pronounced dihedral and whose leading edge was formed by an exposed Fabre beam, was mounted below the rear of the upper beam, and the Gnome Omega rotary engine driving a two-bladed pusher Chauvière propeller was mounted behind it. Additionanal bracing for the wings was provided by kingposts extending down from the leading edge at mid-span. There were two small foreplanes, which like the wing has exposed Fabre beams forming their leading edges, one mounted above the upper beam and the second on the strut connecting the two beams. A rectangular rear-mounted rudder situated above the wing: below the wing there was a similar recangular fixed surface extending town to the lower fuselage beam. The pilot sat astride the upper fuselage beam. It was equipped with three broad floats: one at the front of the aircraft, the other two mounted on struts extending down from the wing.
It successfully took off and flew for a distance of 457 m (1500 ft) on 28 March 1910 at Martigues, France. Apart from the achievement of being the first seaplane in history, Fabre had no flying experience before that day. He flew the floatplane successfully three more times that day and within a week he had flown a distance of 3.5 mi (5.6 km). Then the aircraft became badly damaged in an accident.
These experiments were closely followed by aviation pioneers Gabriel and Charles Voisin. Eager to try flying a seaplane as well, Voisin purchased several of the Fabre floats and fitted them to their Canard Voisin airplane.
Following this experience, Henri Fabre built floats for other aviation pioneers.
