Abstract

UN MODULO DE PROPULSION POR CHORRO DE AGUA, QUE COMPRENDE UNA CAJA CON FORMA DE BARQUILLO QUE TIENE UNA ABERTURA DELANTERA DE ENTRADA DE AGUA CONECTADA A UNA ABERTURA DE DESCARGA DE CHORRO DE AGUA EN LA POPA MEDIANTE UN PASAJE, Y UN IMPULSOR QUE TIENE UNA PLURALIDAD DE ALETAS EN EL PASAJE PARA DIRIGIR EL AGUA DESDE LA ABERTURA DE ENTRADA HASTA LA DE DESCARGA. DICHO PASAJE (46) TIENE UNAPARED ANULAR INTERNA GENERADA ALREDEDOR DE UN EJE CENTRAL (A) Y CUYO DIAMETRO AUMENTA DESDE LA ENTRADA HACIA DESCARGA; TENIENDO LAS PALETAS (34) BORDES EXTERNOS CURVADOS (40) CORRESPONDIENTES CON CURVATURA DE DICHA PARED ESPACIADAS RADIALMENTE HACIA ADENTRO Y MONTADAS EN UN CONO ROTOR CON FORMA PARABOLICA (16); INCLUYENDO DICHA CAJA UNA PARED DE SOPORTE DE UN ESTATOR CON FORMA DE CONO TRUNCADO (18) QUE TIENE UNA SUPERFICIE PARABOLICA QUE FORMA UNA EXTENSION DEL CONO ROTOR; UNA PLURALIDAD DE PALETAS DEL ESTATOR (24) CONECTADAS EN EXTREMOS OPUESTOS A LA PARED DE SOPORTE DEL ESTATOR Y A LA PARED ANULAR INTERIOR, Y QUE TIENEN UNA CURVATURA TAL QUE CONVIERTEN EL FLUJO EN REMOLINO DE LAS PALETAS IMPULSORAS EN UN FLUJO AXIAL HACIA AFUERA DE LAS ABERTURAS DE DESCARGA; Y UN MEDIO DE POTENCIA (M) MONTADO EN LA PARED DE SOPORTE DE ESTATOR Y QUE TIENE UN EJE DE SALIDA DE POTENCIA (50) ACOPLADO A MEDIOS DE TRANSMISION (20) MONTADOS EN EL CONO DE ROTOR, PARA IMPULSAR LAS PALETAS IMPULSORAS A UNA VELOCIDAD MENOR QUE LA VELOCIDAD DE OPERACION DEL MEDIO DE POTENCIA.
