WING-IN-GROUND EFFECT CRAFT Russian patent published in 2006 - IPC B60V1/08 

FIELD: transport; hover craft.

SUBSTANCE: proposed wing-in-ground effect craft has hull in form of aerodynamic lifting wing with central part in form of low-set hull-wing, start-landing device with fan plant to create air cushion, horizontal and vertical tail unit and propulsion power unit, and control system and it contains also aerodynamic sectional wing with central part with angle of attack, leading edge slats, aileron-flaps arranged over lifting wing in form of low-set hull wing in its tail part, and also two aerodynamic cantilever wings of gull type arranged at height exceeding their chord relative to support surface, with angle of attack, with sweepback of leading edge, with leading edge slats, aileron-flaps, and vanes on ends in form of vertical aerodynamic plates. In nose part of lifting wing in form of low-set hull-wing, third wing is installed at height exceeding its chord relative to support surface made sectional and consisting of central part with angle of attach, leading edge slats, aileron-flaps and aerodynamic cantilever wings with angle of attack, sweepback of leading edge, leading edge slats, aileron-flaps, with vanes on ends in form of vertical aerodynamic plates. Aerodynamic cantilever wings of third wing located in nose part of low-set hull-wing can have adjustable and variable in sign angle of attack. Low-set hull-wing can be made with flat lower surface forming angle of attack relative to support surface. Height of third wing in nose part of low-set hull-wing relative to support surface is less than corresponding height of second wing in tail part of low-set hull-wing. Wing-in-group effect craft can be provided with gas discharge channels-nozzle for directing gas jets under bottom of low-set hull-wing are arranged in side their nose part and they serve to form starting air cushion together with static air cushion.

EFFECT: improved operating characteristics of wing-in-ground effect craft.
