A micro-spray high-performance two-body amphibious aircraft

Abstract

The invention provides a slight-splashing high-performance two-hull amphibious aircraft which comprises an aerodynamic lift type main fuselage, wings, empennages, turbofan engines and slight-splashing sliding hulls. The wings 2 are arranged in the middle of the aerodynamic lift type main fuselage. The turbofan engines are arranged on the upper position, near the aerodynamic lift type main fuselage, of the wings. The empennages are arranged at the tail end of the aerodynamic lift type main fuselage. The two slight-splashing sliding hulls are arranged on the two longitudinal sides of the lower portion of the aerodynamic lift type main fuselage. A longitudinal aerodynamic groove channel 5 is formed after the connection of the two slight-splashing sliding hulls and the aerodynamic lift type main fuselage. The aerodynamic lift type main fuselage is provided with reverse profile planing steps which divide the aerodynamic lift type main fuselage into a front fuselage body and a rear fuselage body. An upper transverse bent sliding face and a lower transverse bent sliding face are arranged in the position, at the bottom of each slight-splashing sliding hull, on the sliding face of the front fuselage body sequentially from inside to outside. The anti-wave ability of the amphibious aircraft is improved, and the amphibious aircraft has an excellent hydrostatic and wave splashing controlling ability to adapt to a more complex marine environment.

Description

technical field [0001] The invention relates to the design field of amphibious aircraft, in particular to a micro-spray high-performance catamaran amphibious aircraft. Background technique [0002] For conventional seaplanes, the gliding surface is an obvious V-shaped or W-shaped section. When gliding on the water surface, there is a stagnation point near the free liquid surface at the head of the fuselage where the incoming flow velocity is blocked to zero, and the width range of the bottom of the fuselage A stagnation point line is formed inside, and because the pressure near the stagnation point line is the highest, a huge pressure difference is formed between the stagnation point line and the bottom side of the ship, thereby generating an outwardly moving jet flow, and the height of the splash water flow is closely related to the hull line shape relation. Due to the huge impact of splash on the safety of amphibious aircraft, on the one hand, the cross-section is optimiz...
