Method of manufacturing a rotor for a gas turbine engine that includes identifying the frequency response of the rotor and adjusting the frequency response by providing a pressure gradient within the rotor

摘要

A method of manufacturing a component, the method including the steps of: providing a component having a first portion, which first portion defines a cavity, characterized by; identifying a first frequency response of the first portion and/or the entire component, and introducing material into the cavity to achieve an adjusted frequency response of the first portion and hence a desired frequency response of the component.
