摘要： Disclosed is an insulated container 2 for cooling a heated tooling component 4. The insulated container 2 comprises: a housing including a thermally insulated base 6, an insulated side wall 10 and an insulated upper wall 12 which define a chamber 36 for receiving the tooling component 4; an inlet port 30 passing through the insulated base 6, the inlet port 30 allowing ambient air to enter the chamber 36; and a vent 18 passing through the insulated upper wall 12, the vent 18 allowing air heated by the heated tooling component 4 to be ejected such that a convective air flow through the chamber 36 cools the tooling component 4, wherein a flow area of the vent 18 can be varied to allow an air flow rate through the chamber 36 to be controlled. There is also disclosed a method of cooling a heated tooling component 4.

摘要： An aerofoil structure with a hollow cavity is manufactured by diffusion bonding and superplastic forming. Outer panels are formed of a first material; a membrane is formed of a second material. Stop-off material is applied to preselected areas on at least one side of the membrane or of one of the panels so as to prevent diffusion bonding between the panels and the membrane at the preselected areas. The panels and the membrane are arranged in a stack and a diffusion bonding process is performed to bond together the first and second panels and the membrane to form an assembly. A superplastic forming process is performed at a forming temperature to expand the assembly to form the aerofoil structure. The forming temperature is selected so that the second material undergoes superplastic deformation at the forming temperature and the first material does not undergo superplastic deformation at the forming temperature.

摘要： A method of manufacturing a hollow component, such as a fan blade for a gas turbine engine, includes the steps of: (a) providing first and second panels and a membrane; (b) providing a stop-off material on at least one of the first and second panels and the membrane to define regions where no diffusion bonding is to take place; (c) assembling the panels and the membrane together so the membrane is between the panels; (d) diffusion bonding the panels and the membrane together. The method is such that when assembled in step (c) the membrane does not extend to at least one edge of the first and second panels, so that in that region the first and second panels are diffusion bonded directly to each other.

摘要： The invention is directed to a system and method of applying a coating of lubricant material to the surface of a sheet metal blank in a controlled manner such that some areas of the blank have uniform thickness of lubricant while other areas have no lubricant at all or have a variable amount (progressively increasing or decreasing) of lubricant. This is achieved through the use of a mask template that comprises an overspray fence and at least one contact element. The lubricated coated sheet metal blank is utile for superplastic forming to produce specialized complex shaped parts. The invention advantageously lessens the possibility of skid or slip lines appearing in the finished product as well as lessens the likely build-up of lubricant in forming dies—easing maintenance requirements.
