Abstract

Patente de Invenção "REDUTOR DE ATRITO EM CASCOS DE EMBARCAçõES", composto, basicamente por um compressor de ar, ou depósito sob pressão (1), por coletores de ar (5) e por dutos (2) que conduzem estes gases para a parte submersa da embarcação. Caracterizado por serem os dutos (2) furados (3) em locais apropriados, propiciando a formação de bolhas (4) que escorrem junto ao casco. Estas bolhas (4) exercem uma pressão de baixo para cima, aumentando a capacidade de flutuação das embarcações e reduzindo, consideravelmente, o atrito com a água, possibilitando o aumento da capacidade de flutuação, da velocidade, e a diminuição acentuada no consumo de combustíveis.Invention Patent "FRICTION REDUCER IN SHIPS OF VESSELS", basically composed of an air compressor, or pressure tank (1), air collectors (5) and ducts (2) that carry these gases to the side submerged vessel. Characterized by the fact that the ducts (2) are perforated (3) in appropriate places, providing the formation of bubbles (4) that run down the hull. These bubbles (4) exert pressure from the bottom up, increasing the buoyancy capacity of the vessels and considerably reducing the friction with the water, making it possible to increase the buoyancy capacity, the speed, and the sharp decrease in fuel consumption .
