TUNNEL SHIP HULL WITH DAMPING PLATES Russian patent published in 2017 - IPC B63B1/32 B63B39/06 B63B1/08 B63B1/00 

FIELD: transportation.

SUBSTANCE: tunnel ship hull is proposed that has an above-water hull and an underwater hull with a bottom, designed with at least one longitudinal arcform in cross-section channel along the entire ship hull, the cross-sectional profile of the underwater hull of constructive waterline has a maximum width of stern, curved sides are below the constructive waterline and converge toward the bow, the longitudinal channel is below the constructive waterline and is designed with generatricesparallel to the centreline, and the bottom surfaces between the side walls and the channel are made in the form of two semicones with vertices at the bow and bases in the stern hull ends, while in the stern end of the underwater hull, and the fixed nozzles of jet-propulsion devices are built into its semi-conical formations. Over stil nozzles of jet-propulsion devices, below the waterline from the external side of the underwater hull, at least one horizontal damping plate is installed at each side, with the outer plate edges of are constructively proportional to the above-water hull dimensions.

EFFECT: increased propulsion, navigation and navigability of the tunnel ship.
