SHIP HULL DESIGN REDUCING HYDRODYNAMIC RESISTANCE OF CONVENTIONAL DISPLACEMENT SHIPS

摘要

FIELD: ship building.;SUBSTANCE: invention relates to ship building, particularly to ship hulls with reduced hydrodynamic resistance. Proposed ship hull has its bow section incorporating a spatial grid device. Said spatial grid has channels made by horizontal and vertical planes to fit 1/3 of the ship length in ship bow. Bow of such ship can feature wedge-like shape. Sides of such ship can be arranged vertically and, starting from spatial grid rear edge, get narrowing towards stern in diametral plane at 10 to 14°. Note that ship hull bottom can be flat. Spatial grid can be limited in depth at the bottom level.;EFFECT: producing favorable fluid flow along ship hull in parallel lines to reduce hydrodynamic resistance.;4 cl, 3 dwg
