Abstract

SISTEMA PARA REDUÇÃO DE ARRASTO EM EMBARCAÇÕES. O sistema para redução de arrasto em embarcações consiste num mecanismo composto por dois cilindros (2) com pequeno diãmetro, acoplados a motores que os façam girar com rotação controlada, localizados na popa de embarcação (1) que se deseja reduzir a força de arrasto.TRAIL REDUCTION SYSTEM IN VESSELS. The vessel drag reduction system consists of a mechanism consisting of two small diameter cylinders (2) coupled to motors that rotate them with controlled rotation, located at the stern of the vessel (1) to reduce the drag force.
