Short takeoff and landing amphibious aircraft

Abstract

The invention relates to aviation, in particular to seaplane designs. The amphibious aircraft comprises a fuselage, floats, a wing with wingtips, an empennage, a propulsor, a power plant, a landing gear, main lift hydrofoils and rear water support, and a water rudder. The floats are connected to the fuselage, the wing and the empennage in the shape of a profiled ring by means of strakes, fairings, as well as longitudinal steps along the bottom. The propeller-type propulsor is integrated into the profiled ring, wherein the profiled ring comprises a high-set elevator with profiled lateral surfaces, as well as lateral rudders. An increase in lift-to-drag ratio and efficiency, short takeoff and landing capability, increased stability and controllability of amphibious aircraft are provided.
