Abstract

Destinado a minimizar la incidencia del muy alto coeficiente de rozamiento del agua, conocido en la industria náutica como ôresistencia de pielö, respecto de la superficie de la obra viva de las embarcacion, consistente en la provision de aire desde un compresor a bordo a través de una pluralidad de tubos de distribucion de diámetro mediano (4'' en embarcaciones de porte importante), dispuestos longitudinalmente y de manera equiespaciada en sentido transversal, en adyacencia de la superficie interna del casco comprendida bajo el nivel de flotacion, de los que surgen sendas pluralidades de tubos expulsores acodados de menor diámetro (por ejemplo 1/16''), comunicantes con el exterior de manera homogénea por orificios pasantes provistos de picos calibrados, de forma tal que los pequenos caudales de aire a presion constante que expulsa cada tubo menor se disipan en forma de burbujas con tendencia ascendente que se interponen a modo de microesferas lubricantes entre la superficie externa del casco y la superficie hídrica en contacto, reduciendo el efecto resistente del medio provocado por la viscosidad del medio en el cual se desplaza la ambarcacion.Aimed at minimizing the incidence of the very high coefficient of friction of water, known in the nautical industry as "skin resistance", with respect to the surface of the ship's live work, consisting of the provision of air from a compressor on board through a plurality of medium diameter distribution pipes (4 '' in large vessels), arranged longitudinally and equally spaced transversely, adjacent to the inner surface of the hull comprised below the level of floating, from which paths arise pluralities of angled ejector tubes of smaller diameter (for example 1/16 ''), communicating with the outside in a homogeneous manner through through holes provided with calibrated peaks, so that the small flow rates of air at constant pressure that expel each smaller tube they dissipate in the form of bubbles with ascending tendency that interpose as lubricating microspheres between the outer surface The hull and the water surface in contact, reducing the resistant effect of the medium caused by the viscosity of the medium in which the amber is moved.
