Abstract

1337641 Ship propeller KAKLSTADS MEKANISKA WERKSTAD AB 19 April 1971 [10 April 1970] 20554/71 Heading B7V In a ship's propeller comprising propeller blades detachably mounted on a propeller hub, each blade 1 has a flange 3 which is removably located in a propeller blade site 7 on the hub 9. Hydraulic cylinder 15 is arranged either in each propeller blade or in each propeller blade site and houses a piston 21 which protrudes between the flange and the hub radially relative to the axis of rotation of the propeller.
