METHOD FOR MANUFACTURING A ROTATING PART OF A HYDRAULIC MACHINE, ROTATING PART MANUFACTURED ACCORDING TO THIS METHOD, HYDRAULIC MACHINE AND ENERGY CONVERSION INSTALLATION

摘要

A method is disclosed for manufacturing a rotating part which belongs to a hydraulic machine of an installation for converting hydraulic energy into electrical or mechanical energy. This rotating part includes blades distributed about an axis of rotation of the rotating part and extending from a leading edge to a trailing edge. This method can include manufacturing, in steel, a first part of each blade, which defines the leading edge thereof, manufacturing a second part of the blade in a material other than steel and attaching this to the first part of the blade so as to form a trailing edge.
