船体摩擦阻力降低装置
摘要：
本发明提供一种船体摩擦阻力降低装置，通过产生气泡以在船底形成气泡膜(8)，从而降低航行的船体的摩擦阻力。该船体摩擦阻力降低装置具有：配设于船体内部的船底(5)的空气室(22a)、在成为空气室(22a)底部的船底(5)排列设置而形成的多个空气喷出孔、以覆盖空气室(22a)的方式配设于船体内部的船底(5)的海水箱(35)。由此，可以容易地进行空气室(22a)的维护，并且，可以形成不透水结构以防止海水浸入船体内部。
摘要（英）：

A hull frictional resistance reducing device for reducing the frictional resistance of a running hull by generating air bubbles and forming an air bubble film (8) on the bottom surface of the hull comprises an air chamber (22a) disposed on the bottom (5) of the interior of the hull, a plurality of air jet apertures arranged in a row in the bottom (5) of the hull forming the bottom of the air chamber (22a), and a sea chest (35) so disposed on the bottom (5) as to cover the air chamber (22a), whereby the maintenance of the air chamber (22a) can be easily performed, and the hull can be formed of such a watertight structure that sea water does not intrude into the interior of the hull.
