FIELD: transport, ship building.
SUBSTANCE: air-cushion vehicle incorporates a shell with skegs and is provided with outboard motors, supercharger with air ducts to feed higher-pressure air into the cushion. The proposed air-cushion vehicle features the M-shape cross-section of plating constricting the air-cushion space. The plating of the skeg inner sides, adjoining parts of bottom and pitching section of the bottom are smoothly mated. The clearance in diametrical plane makes at least 1/20 of the width between the lower edges of skegs. The aforesaid air ducts are recommended to be arranged along and outside the vehicles sides. The proposed invention allows reducing the air-cushion vehicle draught to mount standard outboard motors behind the propulsive unit transom.
EFFECT: improved performances, better comfort, enlarged shell payload volume due to arranging air ducts outside vehicle sides.
