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 |
