Abstract
A method of making an aerofoil blisk (10) comprising a plurality of aerofoil blades (12) joined to a disc (14) to extend radially outwardly therefrom includes the step of forming a blade member (28) having a stub (30) for joining to the disc (14), the stub (30) having a taper ratio of less than 2. The stub (30) of the blade member (28) may be joined to the disc (14) by linear friction welding, and excess material may subsequently be machined from the blade member (28) to form the blade (12).
