RIGID SAIL WITH CONFIGURABLE PROFILE

RIGID SAIL WITH CONFIGURABLE PROFILE

Rigid sail of configurable profile. It is formed by a rigid structure (2) with a tapering cross-section, constituted by two convex or concave-convex side rigid walls (3, 4) and faced to each other, joined at two common end edges (5, 6), defining an internal space (7). It comprises closing elastic sh...

Zusammenfassung:Rigid sail of configurable profile. It is formed by a rigid structure (2) with a tapering cross-section, constituted by two convex or concave-convex side rigid walls (3, 4) and faced to each other, joined at two common end edges (5, 6), defining an internal space (7). It comprises closing elastic sheets (13, 14), each associated to one of the rigid walls (3, 4), joined to the corresponding wall in at least a zone; external closed spaces (23, 24) of variable volume, defined between each side rigid wall (3, 4) and each elastic sheet (13, 14); a plurality of perforations (8), provided at the rigid walls (3, 4); means for generating and supplying compressed air to blow air in the external closed spaces (23, 24) through said perforations (8), to blow said elastic sheets (13, 14), increasing the volume of said external closed spaces; and means for generating and supplying vacuum in said external closed spaces (23, 24) through said perforations (8), to deflate said elastic sheets (13, 14), decreasing the volume of the external closed spaces.
