ABSTRACT:
A sectionalized turbine wheel mounted for rotation about a vertical axis and having a plurality of turbine blades mounted to its circumference. There is an outer circumferential feeder pipe surrounding a distribution pipe that defines a distribution chamber, which in turn leads through a plurality of vane assemblies to the turbine blades. The turbine blades are substantially enclosed in a housing structure which provides an annular downward opening. Water under pressure flows into the feeder pipe, thence into the distribution chamber and through the vane means to impinge on the turbine blades, from which the water is discharged in a downward direction. The turbine blades are concave and curve in both a vertical and lateral plane, with the slope of the upper portion of the impact surface having a substantial horizontal component and the slope of the curve of the impact surface at the lower end being predominantly downward, to facilitate directing the water impacting the blades in a downward direction after impact. The main drive shaft from the turbine wheel connects to a speed augmenting gear transmission to rotate an output shaft at an increased rate of speed.
