Abstract
An aerofoil blade for a gas turbine engine is in the form of a heat pipe. The aerofoil blade has an internal passageway adapted to contain a secondary structure and to thermally insulate that secondary structure from the remainder of the aerofoil blade by, for instance, the provision of a cooling air passage between the internal passageway and secondary structure.
