摘要： Air cooling of airfoils in a gas-turbine engine is effected through holes which terminate with a diffuser formation at the airfoil surface. The invention is directed to a two-step procedure whereby a laser beam drills the holes very quickly and cost-effectively and whereby an EDM step is relied upon only to form the diffuser shape. The EDM part of the procedure thus occupies but a fraction of the time previously required, and substantial overall economy is realized by integrating these two steps, which are preferably performed in the order stated but which, if desired, may alternatively be performed by laser driling after EDM formation of the diffuser shape.

摘要： A system for automatically inspecting the true position of cooling holes manufactured in hot section turbine blades and vanes. The system includes a computer controlled rotary tilt table for correctly positioning the blade or vane having the cooling holes, and computer controlled, a coordinate measuring machine for positioning a video camera in the X, Y, Z directions so that it can look straight into the selected cooling hole of the blade or vane. An image analyzer receives the image from the video camera, calculates the centroid of the image, and the host computer calculates and reports deviation between the actual or true position of the cooling hole and data relating to the correct position of the same. A touch probe is also provided with the coordinate measuring machine to verify the correct position of the blade or vane prior to imaging.

摘要： A method is provided for repairing by solid state diffusion a damaged portion of an inner surface of a hole of a metal part. The method comprises machining the hole to a cylindrical diameter sufficient to remove the damaged portion therefrom and provide a new hole with a smooth finish into which a metal bushing is inserted, the outer diameter being of size and finish relative to the machined diameter of the hole to provide a close fit therewith, the composition of the metal bushing being compatible with that of the metal part. A cylindrical metal mandrel of diameter corresponding to the inner diameter of the bushing is inserted into the bushing to provide an assembly thereof with the metal part, the metal mandrel having a mean coefficient of thermal expansion greater than that of the metal bushing for a selected solid state diffusion temperature sufficient to provide pressure against the bushing. The assembly under substantially non-oxidizing conditions is then subjected to solid state diffusion at an elevated solid state temperature corresponding to at least about 50% of the absolute melting point (solidus) of the metal part for a time at least sufficient to diffusion bond the bushing under pressure to the metal part by virtue of the expansion of the mandrel in the bushing at the diffusion temperature. The assembly is cooled to ambient, the mandrel removed, and the inner diameter of the diffusion-bonded bushing machined to an appropriate dimension. The diffusion-bonded part is preferably heat treated prior to machining of the bushing.

摘要： A system and method for reconfiguring a turbine vane. In at least one embodiment, the system may be used to straighten an airfoil of a turbine vane segment to remove lean, twist, or racking, or any combination thereof. The airfoil may be straightened by fixing portions of the forward and aft hooks of the inner and outer shrouds of the turbine vane, restricting other portions of the forward and aft hooks of the inner and outer shrouds of the turbine vane to only move rotationally about a centerline of the inner or outer shrouds, and applying a load to various portions of the inner and outer shrouds and the airfoil to return the turbine vane to be within predetermined specifications.
