The trailing end of the sponsons end in a sharp edge, thus eliminating the need for a hull or float step or venting. A channel is formed by the sponsons and the underside of the fuselage, which channel has a constant cross-section and produces a surface lift effect facilitating take-off and landing. A pair of keels beginning substantially aft of the center of gravity of the airplane provide directional stability on the...
In an amphibious aircraft, having a fuselage with a water-contacting hull, wings, tail assembly, and at least one engine, the improvement wherein said fuselage hull includes sponsons integral therewith extending outwardly on either side of the fuselage, wherein the underside of the combination fuselage and sponsons includes a substantially constant cross section inverted channel, the fuselage further including twin keels extending fore to aft on the underside of said hull, the inner surfaces of said twin keels being substantially extensions of the walls ...
