HIGH-SPEED SHIP WITH BOTTOM GAS LUBRICATION Russian patent published in 2020 - IPC B63B1/38 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding, in particular to designing and construction of planing vessels, which use supply under the bottom of compressed air or exhaust gases to reduce hydrodynamic resistance. Disclosed is a high-speed vessel comprising a housing with a gas-distributing transmission system, comprising a gas duct connected by one end to a marine engine, and other end with distribution gas chamber, communicating with narrow exhaust slots, supplying exhaust gases to lower surface of ship hull, wherein each two exhaust slots are arranged in pairs symmetrically on both sides of longitudinal axis of ship bottom, wherein exhaust slots are formed in ship bottom behind nose edge of wetted bottom surface near it, are directed towards side, opposite to vessel motion direction, at angle to its longitudinal axis, and on the lower boundary of each exhaust slot there is an attachment made in form of a streamlined plank, the length of which is not less than the length of the exhaust slot, and the height depends on the dimensions of the wetted surface of the bottom and the width of the slot.

EFFECT: technical result is to improve the operating characteristics of the vessel.
