METHOD OF FABRICATING INTEGRALLY BLADED ROTOR USING SURFACE POSITIONING IN RELATION TO SURFACE PRIORITY

摘要

A method of fabricating an integrally bladed rotor for gas turbine engines according to one aspect includes a step of positioning a blade on a hub in a joining procedure by using a priority surface of the blade as a reference surface. The priority surface is determined in relation to importance of surface functionality of the blades during engine operation

1. A method of fabricating an integrally bladed rotor of a gas turbine engine, the integrally bladed rotor including a hub with an array of airfoil blades welded to the hub, the method comprising:
a) determining a priority aerodynamic-functional surface of the respective blades in relation to importance of surface functionality of the blades during engine operation; b) positioning the respective blades onto the hub by using an entire finished surface of the determined priority aerodynamic-functional surface of the blades as a reference surface in order to locate a position of the respective blades on the hub; and c) welding the respectively positioned blades to the hub.
