Abstract

Sistema hélice tobera aceleradora para impulsar barcos.#Soluciona obtener mayor rendimiento en barcos, gracias a tobera (4) en la cual, la diferencia (S) entre el radio exterior (Ro) de la tobera (4) y el radio interior (Ri) de la tobera (4) está comprendida entre 0.050D y 0.088D, siendo D el diámetro interior de la tobera (4); de acuerdo con el sentido general de circulación del agua en marcha avante del barco, el extremo anterior de la cuerda (C) del perfil de la tobera (4), presenta mayor distancia respecto at eje de giro (7) de la hélice (10), que el extremo posterior de dicha cuerda (C); y la diferencia entre ambos extremos de la cuerda (C) respecto a la distancia al eje de giro (7) de la hélice (10) es superior a 0.0025D para toda relación L/D, siendo L la longitud axial de la tobera (4).Propeller nozzle propeller system to propel ships. # Solves to obtain greater performance in ships, thanks to nozzle (4) in which, the difference (S) between the outer radius (Ro) of the nozzle (4) and the inner radius (Ri ) of the nozzle (4) is between 0.050D and 0.088D, where D is the inside diameter of the nozzle (4); in accordance with the general direction of water flow in forward motion of the ship, the front end of the rope (C) of the profile of the nozzle (4) has a greater distance from the axis of rotation (7) of the propeller (10) ), that the rear end of said rope (C); and the difference between both ends of the rope (C) with respect to the distance to the axis of rotation (7) of the propeller (10) is greater than 0.0025D for any L / D ratio, where L is the axial length of the nozzle ( 4).
