Alvarez et de Conde
De Conde worked with a Lieutenant Saunier (not Saulnier), a military expert attached to the laboratory at Chalais-Meudon. Traces of 3 designs remain:
1. Seaplane or flyingboat, model only.
2. An odd high-wing flyingboat with streamlined hull and pointed nose, fabricated from 2 layers of cedrat, a kind of lemon-wood, with fabric in between; the pilot was enclosed along with the engine which drove 2 pusher propellers set on the trailing edge. 4 windows provided him with a view, and small winglets provided stability on the water. The low-aspect-ratio wing was in 3 panels with large ailerons, and was supported on the struts based on special floats; it was entirely of metal construction without welding. The machine was tested around August 1913 at Bellevue on the Seine; the results are not known.
(Span: 12 m; chord: 2.2 m; wing area: 26.5 sqm, Eiffel No 8 airfoil; length: 8.4 m; winglet span: 5.7 m; 60 hp watercooled engine)
3. Existed in proposal only: an all-steel 3-seater armored amphibian combat aircraft for the Navy. It featured an auxiliary 8 hp motor to power the radio, and to start the main engine.
