摘要： Large gas turbine blades made from separate cast segments of superalloys are disclosed. The turbine blade is designed such that bond lines between adjacent segments are placed in low stress regions of the blade. The cast superalloy segments of the blades are aligned and fitted together with specified tolerances. The turbine blade segments are then joined by transient liquid phase bonding, followed by a controlled heat treatment which produces the desired microstructure in the bond region. The method allows for the production of large, high quality turbine blades by joining small, high quality cast superalloy sections, in comparison with prior attempts to cast large turbine blades as single pieces which have produced very low yields and high individual component costs.

摘要： A hybrid structure (50) and method of manufacturing the same including a structural ceramic matrix composite (CMC) material (42) coated with a layer of ceramic insulating tiles (24). Individual ceramic tiles are attached to a surface (22) of a mold (20). The exterior surface (32) of the tiles may be subjected to a mechanical process such as machining with the mold in place to provide mechanical support for the tiles. A layer of CMC material is then applied to bond the tiles and the CMC material together into a hybrid structure. The mold may include a fugitive material portion (26) to facilitate removal of the mold when the hybrid structure has a complex shape. Tiles located in different regions of the structure may have different compositions and/or dimensions. The gaps between adjacent tiles may be filled from the outside before the CMC material is applied or from the inside after the mold is removed.

摘要： A visual observation system for monitoring a welding operation being performed in a welding region by a welding torch, the torch having a longitudinal axis and including a housing. The system is composed of a closed light conducting channel supported by the torch and having a first end directed toward the welding region and a second end remote from the first end, and image generating device disposed at the second end of the channel for receiving light entering the channel via the first end in order to generate an image of the scene in front of the first end, a transpatent plate disposed in, and blocking, the light conducting channel for protecting the image generating device against soiling by particles produced by the welding operation, and elements for producing a flow of inert gas past the side of the transparent plate directed toward the first end for opposing the deposition of such particles on the plate. The a light conducting channel is dimensioned such that in at least one direction transverse to the longitudinal axis of the torch, the channel does not project beyond the torch housing.
