Abstract
1335845 Marine propulsion W MACKENZIE 19 May 1971 [17 June 1970] 29289/70 Heading B7V An axial screw type marine impeller combining axial flow with centrifugal throw comprises a rotor A which impels liquid towards a ducted cowling D. The rotor is provided with a plurality of blades A1 and the cowling with a plurality of ducts D1 sunk into its inner surface, the blades and ducts being helically arranged in the manner of multistart screw threads which have a progressively increasing lead towards the end of the helix adjacent the cowling outlet E1. The blades and ducts are respectively of opposite handed helical configuration. The assembly may be mounted on a retractable and rotatable vertical shaft G.
