Hydrofoil seaplane

Abstract

The invention discloses a hydrofoil seaplane, and belongs to the fields of seaplanes and hydrofoils. A hydrofoil device is arranged at the lower end of a fuselage, the hydrofoil device comprises a front hydrofoil and a rear hydrofoil, the front hydrofoil is located at the front part of the lower end of the fuselage, and the rear hydrofoil is located at the tail part of the lower end of the fuselage; the front hydrofoil and the rear hydrofoil both form an included angle of 45 degrees with the horizontal plane; the tail part of the fuselage is provided with a T-shaped empennage; the two ends ofwings are provided with turboprop engines to provide power for the seaplane. The characteristics of a hydrofoil seaplane and a hydrofoil craft are combined , so that the seaplane has rapid and flexible water surface moving capability like a hydrofoil craft, the water resistance borne is greatly reduced, needed power of the engines is reduced, flight on the water surface for a long time can be achieved, engines with lighter weight can be adopted, and therefore the effective load of the hydrofoil seaplane is improved.

Description

technical field [0001] The invention belongs to the field of seaplanes and hydrofoils, in particular to a hydrofoil type seaplane. Background technique [0002] A seaplane is an aircraft that can take off and land on water. At present, in order to be able to slide on the water surface, the seaplane usually has a stepped hull at the bottom of the fuselage, so as to reduce the huge resistance when sliding on the water surface, and at the same time enhance the stability of the water surface movement of the seaplane. [0003] But in the prior art, the seaplane with stepped hull design still faces huge hydrodynamic resistance, and the required power of the engine also increases thereupon when the seaplane takes off from the water surface. When flying in the air, the required power of the engine is compared with It is greatly reduced when gliding on the water surface, which will easily lead to a mismatch of engine power, and at the same time increase the weight of the engine and ...

Problems solved by technology

[0003] But in the prior art, the seaplane with stepped hull design still faces huge hydrodynamic resistance, and the required power of the engine also increases thereupon when the seaplane takes off from the water surface. When flying in the air, the required power of the engine is compared with It is greatly reduced when gliding on the water surface, which will easily lead to a mismatch of engine power, and at the same time increase the weight of the engine and reduce the payload of the aircraft

[0004] Therefore, the traditional seaplane has the following defects: 1. The resistance is relatively large when taking off from the water surface; 2. The engine power of the traditional seaplane does not match, causing the weight of the power system to be too large; 3. Due to the above-mentioned defects, the traditional seaplane cannot be long time glides on water
