HIGH-SPEED SHIP HULL Russian patent published in 2004 - IPC

Abstract RU 2238871 C2

FIELD: shipbuilding; designing high-speed gliding ships.

SUBSTANCE: Center of gravity (CG) of ship's hull lies in one line with center of hydrodynamic lifting force (Cp) of bearing surface of hull both at lifting off water and at rated running speed. Hull is delta-shaped in plan and includes central part and two side wing parts. Each wing part is extended sideways and backward relative to central part for forming open section which adjoins transom of central part of hull. Ratio S21

/A₁ of hull dimensions on existing waterline at rated speed is within 2.5-5.0, where A₁ is area of existing waterline in still water and S₁ is its span.

EFFECT: enhanced hydrodynamic stability of high-speed ship.
