NAVAL UNIT ABLE TO REMAIN AND MOVE SUBMERGED AND ON THE SURFACE

摘要

A naval unit configured to selectively assume both a surface condition and a submerged condition comprises a spindle-shaped main body (11) which has a bottom (15) that develops between a first zone (11a), comprised between a rear stern end (13) and the center line (I), and a second zone (11b), comprised between the center line (I) and a front bow end (12). At least one portion of the bottom (15) provided in the first zone (11a) is provided with a first rounded concave cross section and having a profile defined by a continuous curve, and at least another portion of the bottom (15) provided in the second zone (11b) is configured planing, having a second cross section with a profile defined by two segments (215) converging toward a common vertex (W).
