Abstract

Official abstract text for this publication.

A method for providing a disc of a bladed rotor for use in a gas turbine engine including the steps of determining the location of blade fixing slots to be formed on the disc to receive the roots of respective blades, determining a virtual profile of each slot on the disc, and forming, prior to the slots being formed in the disc, a narrow, axial pilot slot centrally of the virtual profile of each slot.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of making blade fixing slots in a disc of a bladed rotor for use in a gas turbine engine, the method comprising: determining a plurality of circumferential locations on the disc for receiving the blade fixing slots, the blade fixing slots being adapted to receive roots of respective airfoil blades of the bladed rotor; determining a virtual full slot profile of each of said blade fixing slots, the virtual full slot profile being adapted to co…
