WING-IN-GROUND-EFFECT CRAFT Russian patent published in 2005 - IPC

FIELD: aircraft engineering.

SUBSTANCE: proposed wing-in-ground-effect craft consists of front, main and rear low-aspect ratio wings forming air cushion, installed in tandem in direction of movement and adjoining each other. Main wing is formed by upper and lower saucer hull shells connected to each other. Front and rear wings are coupled by bow and stern parts of floats-skegs on which main wing rests. All round vision saucer hull is connected with spaces of floats-skegs by airtight passages. Upper rigid shell of said hull is provided with sealed access hatch and windows. Main tractor engine with propeller and auxiliary control cabin are found in front part of each float-skeg. Auxiliary engine has priopeller arranged in ring holder with rudder mounted on rear end face. Said propeller is secured on transverse support crosspiece coupling stern parts of floats-skegs on which vertical control surfaces are mounted. Bow lifting wing is installed on auxiliary control cabins of floats-skegs.

EFFECT: improved efficiency of wing-in-ground-effect craft, possibility of movement over frozen water surface and snow and at height exceeding height of air cushion.
