Abstract
General aviation class amphibious aircraft which include two fuselages, each having a hydrodynamic surface, the fuselages connected via a primary flight surface and a ducted power plant located aft and above the fuselages. The power plant location removes the fan/propeller arc from water and spray during water-borne taxiing, takeoff and landing. The combination of fuselages, lifting surface and ducting provides an aerodynamically efficient design with a lower center of gravity and protected powerplant for yielding improved performance including increased range and airspeed, together with favorable maneuverability, stability and control characteristics both aerodynamically and hydrodynamically.
