Blisk weld repair
TL;DR: In this article, a blisk airfoil is machined away to create a notch, and a repair is welded in the air-foil to fill the notch.
Patent
Repair of airfoil edges
TL;DR: In this article, the leading and trailing edges of gas turbine engine blades are repaired by cutting away a curved section including the damaged area and forming a blend radius along the repaired edge.
Patent
Integrally bladed rotor fabrication
TL;DR: In this paper, a method is presented for the isostatic forging of integrally bladed rotors, in which deformable hollow single crystal blades are protected from deformation during diffusion bonding to the disk by encapsulation in a ceramic protective shell.
Patent
Forge joining repair technique
TL;DR: In this paper, a method for repair of holes in superalloy or titanium materials by using plugs of the same or similar material and heat treatment, whereby a fully recrystallized joint interface is achieved between the plug and the walls of the hole.
Patent
Method of repairing an airfoil
TL;DR: In this paper, a method for repairing an airfoil is provided that includes the steps of determining repair regions of the airfoils that are likely to be damaged during a period of operation.

Method of fabricating hollow composite airfoils
TL;DR: In this paper, a hollow composite airfoil with an integral internal support rib of fluoroelastomer rubber is formed by bracketing the rib between two silicone rubber mandrels to form a core assembly having a desired aerodynamic shape, then building up on opposite sides of the core assembly separate stacks of laminae of a composite material of graphite (or carbon) and glass fibers impregnated with an epoxy resin, with the two stacks overlapping adjacent to the leading and trailing edges.
Patent
Cooled turbine blade and its manufacture
TL;DR: A turbine blade includes a hollow strut covered with a porous laminated material to provide a cooled blade portion and includes a supporting strut portion terminating in one or two bases for attachment to a turbine wheel as mentioned in this paper.
Patent
Method of fabricating a hollow article
TL;DR: In this paper, a method of fabricating a rotor blade is described, comprising the steps of forming a solid piece of material and establishing a reference datum thereon, cutting the piece into two parts and establishing aligning means for adjacent surfaces of the two parts.
Patent
Apparatus and method for refinishing turbine blade airseals
TL;DR: In this paper, a worn or damaged airseal is removed by abrasive belt grinding perpendicular to its length to create a stub, then a piece of material is joined to the stub, as by welding.
Patent
Method of friction welding
TL;DR: In this paper, the interface surfaces of the interface portions are placed in spaced apart opposed relationship and then the airfoil casting and the wrought base member are friction welded at their interface portions.
