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 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 comprises blades distributed about an axis of rotation of the rotating part and extending from a leading edge to a trailing edge (2082). This method comprises steps consisting in manufacturing, in steel, a first part (208A) of each blade, which defines the leading edge thereof, manufacturing a second part (208C) 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.
