Method of forming air film on submerged surface of submerged part-carrying structure and film structure on submerged surface

摘要

The invention provides a method of reducing the fluid friction resistance of a hull and a fluid transport passage, and preventing a submerged part-carrying structure from being soiled and corroded. A method of forming an air film on a submerged surface of a submerged part-carrying structure, consisting of the steps of coating a submerged surface of a submerged part-carrying structure (hull) with a film having recesses (6) and projections (7) in and on its outer surface with the top portions of at least the projections (7) out of these recesses and projections formed out of a water repellent material, and supplying air a onto a film surface (10) thus formed, so as to form an air film (12) between the film surface (10) and water (13).
