METHOD OF MANUFACTURING OF INFLATED SHIP BOTTOM (VERSIONS) Russian patent published in 2017 - IPC B63B9/00 B63B7/08 

FIELD: mechanical engineering.

SUBSTANCE: invention is relevant to small-size shipbuilding and consists of four design variants. For manufacturing inflated ship bottom inner partitions are fastened to bottom material from inner bottom side along symmetry axis. According to the first variant convexities are made between partitions, and material laid in the place of their making occupies large area. According to the second variant convexities are made between partitions, and material laid in the place of their making occupies large area, and utmost partitions placed referenced to convexity are separated into other sides and fastened. According to the third variant two surfaces of material are mounted between partitions. Their counter edges are cut out in the form of two joined curved lines, and nearest partitions referenced to convexity are separated into other sides and fastened. According to the fourth variant lateral convexities are made on material, and partitions are fastened on material at intervals in the place of their making referenced to surface of deck and/or bottom and laterally to symmetry axis. Length of material that forms convexity is more or less or equal to length of partitions' segments in intervals.

EFFECT: simplification of design, increase of assembly rate and decrease of ship weight are achieved.
