Abstract

Sistema propulsor por chorro de agua con mayor eficacia y mejor gobernabilidad. El sistema propulsor por chorro de agua utiliza barras en voladizo para una rejilla de admisión, para evitar el bloqueo. El sistema propulsor por chorro de agua utiliza también una carcasa de eje de impulsor elíptico para reducir la turbulencia y la acumulación de suciedad por parte del eje rotatorio del impulsor. El sistema propulsor por chorro de agua utiliza álabes propulsores con una sección transversal curvada que se curva hacia la dirección de rotación de avance. El sistema de chorro de agua utiliza bridas en forma de U montadas a la salida del chorro de agua para facilitar la dirección.
