Abstract:
1. A method for replacing a blade of an integrally bladed rotor, the integrally bladed rotor including a rotor main body having radial projections on to which blades are joined, the radial projections extending radially from an outer periphery of the rotor main body, the method comprising the steps of: removing a blade of the integrally bladed rotor by cutting through the blade leaving a stub of the blade projecting from the rotor main body, said cutting that removed the blade defining a separation surface on the stub; forming a base on the separation surface; forming a blade connection surface on the base, and joining a new blade to the blade connection surface; wherein the base is formed using a generative manufacturing method, wherein a radial distance (a) between the blade connection surface and the outer periphery of the rotor main body is equal to a radial height of the radial projections prior to said cutting.
