Abstract

1. Una hélice propulsora de buque que comprende dos o más aspas huecas perforadas, montadas sobre un buje dotado de un paso, caracterizada porque cada aspa hueca está perforada en su cara de succión, y mediante un paso existente a través del buje, se comunica con la cara de empuje de la hélice. 2. Una hélice propulsora de buque, según la reivindicación 1, caracterizada porque cada paso existente a través del buje en la cara de empuje de la hélice está dirigido en posición sensiblemente paralela al eje geométrico de rotación. 3. Una hélice propulsora de buque, según las reivindicaciones 1 ó 2, caracterizada porque las perforaciones están dispuestas paralelas a la línea de tracción y, según se mira en la dirección de rotación de la hélice, justamente por detrás de la misma. 4. Una hélice propulsora de buque.
