Abstract

Η εφεύρεση αφορά μια προπέλα για ένα θαλάσσιο όχημα, η οποία περιλαμβάνει μια πλήμνη (12, 112, 212, 312) και τουλάχιστον δύο πτερύγια, τα οποία πτερύγια εκτείνονται προς τα έξω από την πλήμνη (12, 112, 212, 312) κατά την ακτινική κατεύθυνση, και η προπέλα έχει ομοιόμορφη κατανομή πτερυγίων. Το πρόβλημα που αντιμετωπίζει η εφεύρεση είναι η παροχή μιας προπέλας για ένα θαλάσσιο όχημα, η οποία επιτρέπει την αποτελεσματική μείωση ή την αποφυγή της ανεπιθύμητης δημιουργίας θορύβου. Σύμφωνα με την εφεύρεση, η γωνιακή απόσταση μεταξύ των άκρων των πτερυγίων δύο διαδοχικών πτερυγίων της προπέλας μεταβάλλεται σε σχέση με τη γωνιακή απόσταση μεταξύ των άκρων των πτερυγίων δύο άλλων διαδοχικών πτερυγίων.
