Abstract: A method of manufacturing a hollow aerofoil component for a gas turbine engine includes using a capping panel to cover a pocket in a pocketed aerofoil body. During manufacture, the outer surface of the capping panel is located relative to the pocketed aerofoil body. This ensures that the outer surface of the capping panel is located as accurately as possible. This means that the capping panel can be made to be as thin as possible, which in turn reduces weight and material wastage. Once the capping panel has been located in position, it may be welded to the aerofoil body in order to produce the hollow aerofoil component.

Abstract: A method of manufacturing a hollow aerofoil component for a gas turbine engine comprises using a capping panel to cover a pocket in a pocketed aerofoil body. The pocketed aerofoil body has a ledge of substantially constant thickness that extends around its perimeter, and to which the capping panel is joined (e.g. welded) during manufacture. This ensures that the geometry of the join is consistent around the perimeter, meaning that the resulting join has improved properties, for example in terms of residual stress and/or distortion.
