Abstract
A method of manufacturing a filled aerofoil component () for a gas turbine engine () comprises using a capping panel () to cover a pocket () in a pocketed aerofoil body (). During manufacture, a pre-formed filler insert () is provided to support the capping panel () in the correct position. 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. The pre-formed filler insert () provides a lightweight core for the finished aerofoil component in use.
