PLANING HOVERCRAFT Russian patent published in 2021 - IPC B63B1/18 B63B1/38 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and relates to the design of planing hovercraft with skegs. A planing hovercraft is proposed, comprising a hull with a bow step, an engine compartment, on the displacement surface of which there are propellers - propellers, an air cushion bounded by a nasal step, the bottom of the hull, gliding side skegs and a displacement surface of the engine compartment, while the nasal step is made along an arc of a circle from the bow to the bottom of the hull, and the planing side skegs are made with aft sections protruding along the length of the hull transom, the engine compartment is located between these sections and is connected to the hull transom by a hinge, wherein between these sections, the engine compartment and the transom of the hull, a buffer cavity is formed, which is pneumatically communicated with the cavity of the air cushion, the engine compartment is made with a channel pneumatically communicating the buffer cavity with the atmosphere with a check valve that closes this channel from the side of the buffer cavity, and the supporting displacement surface of the engine the compartment is cylindrical.

EFFECT: invention allows reducing energy costs for creating an air cushion and increasing its shock-absorbing properties.
