A two-piece washer to allow tilting movement of the washer elements. One annular washer element includes a convex annular surface that engages with a concave annular surface of a second annular washer element. When the convex and concave surfaces of the respective washer elements are placed in face-to-face engagement, the elements of the two-piece washer can pivot relative to each other. When utilized in a bolted connection, such two-piece washers can allow shifting of the bolted components relative to each other without imposing bending loads on the connecting bolt.

A variable stator vane assembly and a bushing thereof. The bushing includes a metal bushing body and a wear-resistant coating. The assembly includes a rotatable trunnion and a first metal bushing. The trunnion is capable of being located in a through hole extending between outer and inner surfaces of a compressor casing of a gas turbine engine. The first metal bushing is capable of being located in the through hole proximate the outer surface to surround a first portion of the trunnion when the trunnion is located in the through hole. The first metal bushing and the first portion have wear-resistant coatings which are in mutual contact, apart from any intervening lubricant, when the trunnion and the first metal bushing are located in the through hole and the trunnion is rotating with respect to the first metal bushing.

216/100000, 216/108000

A method for chemical milling of a gas turbine engine blisk having a hub and a plurality of blades made of metal for the purpose of changing the dimensional characteristics (i.e., chord and/or thickness) of one or more of these blades. At least one blade of the blisk is treated with a chemical etchant of the metal that the blade is made of for a period of time sufficient to change at least one of the chord and thickness of the blade(s). In a preferred aspect of this method, at least one of the blades of a rotationally imbalanced blisk is treated with the chemical etchant for a period of time sufficient to change the chord and/or thickness of these blades so that the blisk is rotationally balanced.

At least one blade of the blisk is treated with a chemical etchant of the metal that the blade is made of for a period of time sufficient to change at least one of the chord and thickness of the blade(s). In a preferred aspect of this method, at least one of the blades of a rotationally imbalanced blisk is treated with the chemical etchant for a period of time sufficient to change the chord and/or thickness of these blades so that the blisk is rotationally balanced. In another preferred aspect of this method, an assessment of where and the degree to which the rotational imbalance exists in the blisk is made to determine which blades are to be treated with the chemical etchant and how those blades are to be treated to achieve rotational balance of the blisk.

An improved windage shield is provided for use with turbomachinery members partially defining an internal flow path wherein the members are connected by a fastener which protrudes beyond one of the members. The windage shield comprises a portion which is captured between the fastener and one of the members and a cylindrical section which extends downstream of the members to form a smooth cover for isolating the members from the internal fluid flow. The protruding fastener end is recessed into, and generally flush with, the captured portion of the windage shield.

Gas turbine engine fan blade with a metallic airfoil having a leading edge, a trailing edge, and a radially outer tip, and at least one laser shock peened surface located along the leading edge with a region having deep compressive residual stresses imparted by laser shock peening (LSP) extending into the airfoil from the laser shock peened surface.
