Abstract: A seal and method of making seals utilizes folds in order to form creases in a length of material such that the creases reinforce individual seal elements or surfaces while perforations or slots in a seal edge allow air leakage from one side of the seal element or surface to the other. Thus, air pressurization can take place between spaced seal elements or surfaces and this allows air flotation or riding of a rotating component relative to a static housing component. The perforations are typically graduated from the seal edge in order to provide the best pressurization and air-riding effect for proximity or gap control between the sealing edge and the rotating component surface. The slots effectively provide flexibility to the sealing edge such that the seal component emulates a brush seal.

In another embodiment, the cleaning tool cover may include a plurality of flaps for attaching the tool cover to the cleaning tool.

Abstract: Vanes are generally hollow with a passage through which service pipes extend. These service pipes must be connected such that they can allow for thermal expansion and contraction but also anti rotation features are needed in order to prevent damage when a supply coupling is connected through a pipe end. This anti-rotation feature is generally provided between a top hat and a pipe end through flanges. In order to allow reduced spacing between the top of the vane and a casing the flanges are arranged to allow at least recessing of a first flange into a passage opening profile whereby those flanges inter-engage with second flanges at a surface interface to prevent rotation.

Abstract: A method of fabricating or reparing a blisk (10) that comprises a plurality of blades (14) attached to the outer periphery of a disc (12). Blades (14) are formed separately from the disc (12) and are attached to stubs (13) on the disc (12) by friction welding. A metal powder, such as titanium, is sprayed onto the stubs (13) to reinforce them during the friction welding process. Once the stub (13) has been coated with the powder spray, plates (20) are fastened on the disc (12) between which the sprayed coating (18) is clamped. The plates (20) restrain the sprayed coating (18) to prevent delamination during friction welding. Once each of the blades (14) has been welded onto the respective stubs (13) the clamping plates (20) are removed and the sprayed coating (18) is machined away.

Abstract: A gamma titanium aluminide alloy consisting of 46 at % aluminium, 8 at % tantalum and the balance titanium plus incidental impurities has an alpha transus temperature T? between 1310° C. and 1320° C. The gamma titanium aluminide alloy was heated to a temperature T1=1330° C. and was held at T1=1330° C. for 1 hour or longer. The gamma titanium aluminide alloy was air cooled to ambient temperature to allow the massive transformation to go to completion. The gamma titanium aluminide alloy was heated to a temperature T2=1250° C. to 1290° C. and was held at T2 for 4 hours. The gamma titanium aluminide alloy was air cooled to ambient temperature. The gamma titanium aluminide alloy has a fine duplex microstructure comprising differently orientated alpha plates in a massively transformed gamma matrix. The heat treatment reduces quenching stresses and allows larger castings to be grain refined.
