Abstract

Bootsantriebsschraube mit mindestens zwei endseitig an einem Anriebswellenflansch (1) symmetrisch angeordneten Propellerblättern (2a, 2b, 2c), wobei an der Anströmkante jedes Propellerblatts (2a, 2b, 2c) eine Einströmöffnung (3) eines sich von hier aus verengenden Kanals (5) vorgesehen ist, der im Bereich der Rückkante des Propellerblatts (2a; 2b; 2c) in eine Ausströmöffnung (4) mündet, um eine Leistungssteigerung des Antriebs zu erzeugen, wobei das Propellerblatt (2a; 2b; 2c) aus einem U-förmigen Metallblech hergestellt ist, dessen einander gegenüberliegenden Schenkelseiten (6a, 6b) gemeinsam mit der Bodenseite (7) den sich verengenden Kanal bilden.
