Abstract

SE DESCRIBE UN SISTEMA Y METODO PARA CONTRARESTAR EL ACERCAMIENTO MARINO DE POR EJ., EL CASCO DE UN BARCO (1), DONDE UNOS TRANSDUCTORES DE VIBRACION DE BAJA FRECUENCIA ELECTROMECANICOS (2, 3) ESTAN MONTADOS EN PAREJAS ALREDEDOR DE LINEAS NODALES FIJAS ("DURMIENTES") (4) DEL CASCO (1) , Y DICHOS TRANSDUCTORES (2, 3) SON DIRIGIDOS EN UNA RELACION DE FASE OPUESTA PARA IMPARTIR UN MOVIMIENTO A LAS PARTICULAS DE AGUA QUE ES PARALELO AL CASCO (1) INMEDIATAMENTE FUERA DE DICHAS LINEAS NODALES (4), EN ADICION A LOS RELATIVOS MOVIMIENTOS DE LAS PARTICULAS DE AGUA JUSTO FUERA DE LOS TRANSDUCTORES (2, 3), CUYOS MOVIMIENTOS ESTAN EN DIRECCION PERPENDICULAR AL CASCO. ESTA INVENCION COMPRENDE TAMBIEN UNA COMBINACION DEL SISTEMA MECANICO SUPERIOR Y UN REVESTIMIENTO DE SUPERFICIE ESPECIAL QUE CONTRARRESTA EL ACERCAMIENTO DE OTROS ORGANISMOS QUE LOS AFECTADOS POR EL MOVIMIENTO DE LAS PARTICULAS DE AGUA EN UN ALCANCE DE INFRA-FRECUENCIA.
