An hydraulic turbine includes a rotatable turbine runner. The turbine runner has a circumferential inlet for receiving a fluid and an axial outlet for discharging the fluid. The turbine runner also includes a conical-shaped hub rotatable about a central axis, the hub having a diameter that decreases in size from the inlet to the outlet, the conical-shaped hub including a base having a circumference adjacent the inlet and a surface sloping inwardly toward the central axis, the surface including a concave section facing the inlet when viewed in the meridio...


[ Having described the invention, we claim:] [1.] A hydraulic turbine comprising a turbine runner having at least two runner blades each having a corkscrew configuration, wherein the turbine runner is at least 80% efficient at its best efficiency point and achieves a rate of pressure change less than 80 psi/second at substantially all points along the main flow.
