Abstract

SE DESCRIBE UNA DISPOSICION DE ALETAS DE REACCION PARA USO MARINO QUE ES SENCILLA DE ESTRUCTURA, DE BAJO COSTE, EXCELENTE RENDIMIENTO Y ECONOMICA. LA NUEVA DISPOSICION COMPRENDE ALETAS DE REACCION (7A Y 7F) SUPERIORES RELATIVAMENTE LARGAS, PROLONGADAS A NIVELES SUPERIORES AL DEL ARBOL DE LA HELICE (5A), Y ALETAS INTERMEDIAS (7C Y 7D) Y ALETAS INFERIORES (7C Y 7D) PROLONGADAS A NIVELES SUCESIVAMENTE INFERIORES A LOS DE LAS ALETAS DE REACCION SUPERIORES Y QUE TIENEN LONGITUDES SUCESIVAMENTE MAS CORTAS QUE LAS DE LAS ALETAS DE REACCION SUPERIORES. LOS ANGULOS DE MONTAJE DE LAS ALETAS DE REACCION DEL COSTADO EN QUE LAS ALETAS DE LA HELICE DESCIENDEN CUANDO LA HELICE EFECTUA UNA ROTACION DE AVANCE SE ESCOGEN MAYORES QUE LOS ANGULOS DE MONTAJE DE LAS ALETAS DEL COSTADO OPUESTO. EN LA POSICION SEPARADA DEL EJE DE LA HELICE UN 35 POR CIENTO DEL DIAMETRO DP, SE ESCOGE UN INTERVALO IO ENTRE UN BORDE DELANTERO DE LA HELICE Y UN BORDE TRASERO DE LA ALETA DE REACCION QUE SEA DEL 15 POR CIENTO AL 25 PORCIENTO DEL DIAMETRO DP DE LA HELICE, Y SE ESCOGE UNA LONGITUD DE CUERDA CF DE LA ALETA DE REACCION EN LA MISMA POSICION QUE SEA DEL 10 POR CIENTO AL 20 POR CIENTO DEL DIAMETRO DE LA HELICE DP.A DISPOSITION OF REACTION FINS FOR MARINE USE IS DESCRIBED, WHICH IS SIMPLE IN STRUCTURE, LOW COST, EXCELLENT PERFORMANCE AND ECONOMIC. THE NEW PROVISION COMPRISES REACTION FINS (7A AND 7F) RELATIVELY LONG, PROLONGED AT LEVELS HIGHER THAN THE HELICE TREE (5A), AND INTERMEDIATE FINS (7C AND 7D) AND LOWER FINS (7C AND 7D) PROLONGED TO LONG LOWER THAN THOSE OF HIGHER REACTION FINS AND HAVE SUCCESSIVELY LONGER THAN THOSE OF HIGHER REACTION FINS. THE MOUNTING ANGLES OF THE REACTION FINS OF THE SIDE IN WHICH THE PROPELLER FINS DESCEND WHEN THE PROPELLER MAKES AN ADVANCE ROTATION ARE CHOOSED GREATER THAN THE MOUNTING ANGLE OF THE OPPOSITE SIDE FINS. IN THE SEPARATE POSITION OF THE PROPELLER SHAFT 35 PERCENT OF THE DP DIAMETER, AN IO INTERVAL IS CHOSEN BETWEEN A FRONT EDGE OF THE PROPELLER AND A REAR EDGE OF THE REACTION FLAP THAT IS 15 PERCENT TO 25 PERCENT OF THE DP DIAMETER OF THE PROPELLER, AND A CF ROPE LENGTH OF THE REACTION FIN IS CHOSEN IN THE SAME POSITION WHICH IS 10 PERCENT TO 20 PERCENT OF THE DIAMETER OF THE PROPELLER DP.
