Hull configuration for submarines and vessel of the displacement type with multihull structure

摘要

This invention relates to a design of a ship hull, and more particularly, to cargo ship or submarine configurations featuring flow channels on the hull surfaces, and multihull structure, and improved diving and surfacing properties, and reduced hydrodynamic resistance, and improved hull damage resistance, and further comprising underwater hub cargo loading and unloading, and relates to manned or unmanned or semi-autonomous sea vessels. A hull design consists of a curvative hull form transversally and symmetrical about its center line CL and design water line, and consists of ballast and storage tanks and cargo compartment within the hull portions and operable to adjust the draft and the depth of the vessel according to the loaded weight, and provides detachable installation options. The invention relates to a ship hull design with reduced block coefficient (Cb) values.
