Abstract
A propeller type runner is described in which the leading edge of each blade "leans" forward from the root in the direction of rotation to reduce cavitation and increase efficiency. The "lean" provided to each blade of a five blade design is such that the leading edge of each blade obscures a large portion of the trailing edge of the preceding blade.
