Abstract
A method of manufacturing a rotating component, the method comprising the providing a component comprising a first portion, which first portion defines a first cavity, characterised by; identifying a first inertial property of the first portion and/or the entire component, introducing material into the first cavity to achieve an adjusted inertial property of the first portion and hence a desired inertial property of the component. A rotating component including a first portion defining a first cavity, a second portion defining a second cavity, the second portion being circumferentially spaced from said first portion, the first cavity has a first material deposit therein, said material having predetermined inertial characteristics so as to adjust the centre of mass (Z) of the rotating component.
