Abstract (en)
[origin: WO9738897A1] A blade for ship propellers is provided in the area of its outer radius with means for reducing the induced turbulence. The means for reducing the induced turbulence consist of several ribs spaced apart and arranged next to each other in an approximately parallel direction to the generatrix of the propeller blade. The ribs project freely outwards in the radial direction from the end of the propeller blade.
