METHOD FOR MAKING AN INTEGRALLY BLADED ROTOR WITH HOLLOW BLADES

摘要

A method of making an integrally bladed rotor with hollow blades. A plurality of segmented layers are sequentially placed to form each one of a plurality of blades on a radially outward surface of a hub. This is done using an additive manufacturing process. The placement of the segmented layers also comprises omitting portions of one or more of the plurality of segmented layers to form one or more cavities and intermittently removing a quantity of particles from the one or more cavities using an evacuation tool.

1. A method of making a integrally bladed rotor comprising a hub and a plurality of hollow blades, the method comprising:
forming each of a plurality of hollow blades by using an additive manufacturing process to integrally form a plurality of segmented layers successively outward from a radially outward surface of a hub; while forming the plurality of hollow blades, forming one or more cavities in one or more of the plurality of hollow blades by omitting a portion of one or more of the plurality of segmented layers and periodically evacuating a quantity of excess material from the one or more cavities.
