发明名称 Amphibious aircraft
摘要 An amphibious airplane having an engine assembly mounted at a top center location in the fuselage, and a tail assembly having a horizontal fin in an elevated position so as to be in the propeller air stream. A lift augmenting aerodynamic surface is positioned at the top middle portion of the aircraft fuselage, with the propeller being at the concavely curved rear end of the lift augmenting surface. A pair of platforms are positioned on opposite sides of the fuselage at lower locations adjacent to a passenger section of the aircraft. These platforms are aerodynamically aligned and also have strakes extending forwardly therefrom along opposite sides of the fuselage. In cruise mode, the increased velocity imparted to the propeller air stream acts on the horizontal fin to exert a downward force, with the various forces of the airplane balancing each other. With increased power setting of the engine, the increased velocity of the propeller air stream enables the horizontal tail fin to exert a greater downward force to maintain stable operation of the aircraft.
