VEHICLE BODY Russian patent published in 2012 - IPC B63G8/00 B63B3/00 

FIELD: transport.

SUBSTANCE: invention relates to shipbuilding and refers to vessel hull lines engineering. Vessel hull consists of fore end, centre section and aft end and contains propellers in fore and aft ends. The hull is made symmetrical both in centreline plane and in horizontal plane of symmetry. Propellers are made as channels with actuating elements. The propellers are installed near hull with gaps in the form of inlet and outlet slits with possibility tangential blowing and/or suction of fluid on curved hull surface. In all hull cross-sections which are parallel to centreline plane, symmetrically to horizontal plane of symmetry, fore end is made with surface in the form of circumference quarter from outlet slits of fore end propeller to centre section. Hull centre section is made as cylindrical insert with horizontal generatices. Hull aft end is made with surface in the form of half of sphere segment from centre section to inlet slits of aft propeller with R/h ratio not less than 2.5, where R is sphere segment radius, h - maximum sphere segment height from centre section to inlet slits of aft propeller.

EFFECT: increased vehicle propulsive coefficient.
