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

FIELD: aircraft engineering.

SUBSTANCE: invention relates to hydraoplanes with cavitation cavities on area of end plates of wind. Proposed wing-in-ground-effect craft has hull and design of wing with opposite wing tips and pair of supercavitating end plates. Each end plate is extended downwards from corresponding said wing tip for said hull and wing lower than hull for constant dipping in water in flight. Nose of each plate is made to create super cavitating cavity at cruising speed stretched along length of plate. To contribute to elongation of supercavitating cavity at low speeds, projecting ribs can be provided lower in flow from each nose. To prevent damage of end plates by pressure of water at angle of drift in flight, at least rear parts of end plates are made displaceable in cross direction, for instance, by turning around vertical axis. Said "setting to flow: of end plates levels them relative to water flow and makes it possible to use more narrow end plates.

EFFECT: improved wing-in-ground-effect craft with end plates capable of dipping in water or operating in dipped position.
