Abstract: PROBLEM TO BE SOLVED: To obtain an improved polyurethane compound usable as an embedding resin for a fan outlet guide vane assembly of a commercial gas turbine engine. SOLUTION: A polyurethane compound suitable for this invention is obtained by mixing a polyurethane prepolymer preparation with an aromatic amine curing agent in the ratio of about 0.9: about 1 to 1:1, preferably about 0.95:1 to about 1:1. The polyurethane prepolymer preparation related to this invention comprises a blend mixture obtained by blending different polyethers composed of diphenylmethane diisocyanate (MDI) as a base and the amine curing agent is a blended mixture of an oligomeric diamine and an aromatic diamine containing a catalytic component. These blend mixtures are both liquid at a room temperature.

Abstract: Techniques are described for the formation of an abrasive surface layer (14) on an article (12). The surface layer (14) is characterized by a single layer of particles (18) which are evenly spaced apart, in a high density arrangement, within a metallic matrix (16). In the deposition of the particles (18) on the article (12), a vacuum is drawn through a perforated plate (42), wherein the location of each perforation (44) corresponds to the desired location of one particle (18) on the article surface (11). The vacuum holds one particle (18) over each perforation (44) in the plate (42), then the plate (42) is positioned over the article (12) and the vacuum level adjusted so that the particles (18) fall onto the article (12). The matrix (16) is then deposited by plasma arc spraying a superalloy powder. The invention is particularly suited to the formation of an abrasive layer on the tip surface of a blade used in a gas turbine engine.

Abstract: A fixture 56 for disposing laser blocking material 52 on the interior of an airfoil 10 is disclosed. Various construction details are developed which allow for the repetitive disposition of the laser blocking material in one airfoil after another. In one embodiment, the fixture includes a sprue plate 62 and locating block 126 which are spanwisely spaced and engage the ends 14, 18 of the airfoil.

Abstract: A method and material 52 for blocking a laser beam L during laser machining is disclosed. The material comprises a thermoplastic polymer. Various details are developed which promote filling and removing the blocking material from a component 10. In one detailed embodiment, the thermoplastic polymer is formed of only carbon and hydrogen and forms harmless effluent during burnout of the material.

Abstract: A method for disposing laser blocking material 52 on the interior of an airfoil 10, such as a rotor blade or stator vane, includes shear thinning the material. Various steps are developed which promote decreases in viscosity of the blocking material. In one detailed embodiment, the material is passed through an injection molding machine 54 to provide shear thinning.
