SHIP HULL OF DUCT- AND HYDRO-KEEL TYPE Russian patent published in 2017 - IPC B63B1/38 B60V3/06 

FIELD: mechanical engineering.

SUBSTANCE: invention is relevant to the field of shipbuilding and concerns designing ship hull of duct- and hydro-keel type. The proposed ship hull of duct- and hydro-keel type is equipped with above- and underwater parts of hull with curved board below constructive waterline; and bottom, which is provided with longitudinal duct equipped with upper horseshoe-like arch and vertical walls. Movable enclosure of forward end is manufactured according to type of retractable multilayer balaclava, which is equipped with mechanism for lifting and descent. Movable enclosure of aft end is manufactured in the form of flat system that is two-ply and fixed with the aid of bends on rod and/or on tube of elastomer canvases, which free ends lay on top of each other. Nearby ship forward- and aft ends two high-pressure air pumps are mounted on axis suitable for fixed deviation from vertical line by 30° at most within longitudinal plane of ship. Movers of hydro-jet type placed in underwater housings are manufactured according to hollow cross-flow scheme, when rotor part of mover is of discontinuous and ring type and built into stator part.

EFFECT: proposed invention results in increase of performance parameters of ship belonging to duct- and hydro-keel type.
