Abstract

ENSAYOS DE CAVITACION EN HELICES. SE CARACTERIZAN POR AUMENTAR EL DENOMINADOR DEL INDICE DE CAVITACION DEL MODELO (1). CONSIGUIENDOSE BIEN POR LAS REVOLUCIONES DEL PROPULSOR O POR MEDIO DE LA VELOCIDAD DE REMOLQUE DEL MODELO (1) PARA CONSEGUIR LA IGUALDAD DE LOS INDICES DE EL MODELO (1) Y DEL BOQUE REAL. DICHOS ENSAYOS SE PUEDEN REALIZAR EN CANALES DE EXPERIENCIAS, EN EL MAR O EN UN LAGO PUDIENDOSE IGNORAR O NO LA COMPONENTE AXIAL DE LA VELOCIDAD DE ESTELA DEBIDO A LAS OLAS (6). EL MODELO (1) INMERSO HASTA LA LINEA (5) ESTA DOTADO DE UNA ZONA DE PROTECCION (2) PARA EVITAR LA ENTRADA DE AGUA EN SU INTERIOR, DE LOS SOPORTES DE ENGANCHE (3), LA SALIDA DE CABLES DE INSTRUMENTACION (4) Y LA ZONA DE OBSERVACION DE LOS ENSAYOS (7). EL CALADO DE POPA (9) SOBRE LA HELICE (8) ES REGULABLE SEGUN LA CARGA CON QUE SE DOTE AL MODELO (1), PUDIENDOSE CALCULAR EL PARAMETRO "O" POR LA DIFERENCIA ENTRE LA OLA (6) Y LA LINEA (5). SI SE ACEPTA LA FORMACION DE OLAS, AL MODELO SE LE DOTA DE UNA CHAPA DE ACERO (11) A LO LARGO DE SU BORDA.
