Abstract: A process for forming a molded polymer resin fiber tube clamp, as well as the tube clamp formed by that process. Continuous top and bottom plies provide increased resistance to delamination/cracking as they sandwich a filler material. The tube clamp is free from exposed fiber ends so than no wear is produced on a tube being clamped.

Abstract: A brush seal for use in a rotary machine includes a rotary component disposed inside a stationary component. A brush sealing system is disposed between the stationary component and the rotary component. The brush sealing system includes a seal housing that contains a matrix of potting compound, coupled to the stationary component. A plurality of bristles is provided, each bristle having a first end embedded in the potting compound and a second end protruding from the seal housing towards the rotary component. The potting compound is formed from a ceramic suitable for use at high temperatures that is capable of bonding to non-metallic bristles.

Abstract: A method enables a variable vane assembly for a gas turbine engine including a casing to be assembled. The variable vane assembly includes a seal assembly and at least one variable vane that includes a platform and a trunnion, wherein the platform extends outwardly from the trunnion. The method comprises coupling a seal assembly journal bushing to the variable vane such that the journal bushing is against the trunnion and between the trunnion and the engine casing, and wherein the journal bushing has a substantially constant diameter extending between a first and a second end of the journal bushing, and positioning a substantially flat first washer on the variable vane ledge to prevent contact between the variable vane assembly and the engine casing.

Abstract: A variable stator vane assembly for a gas turbine engine including a bushing that facilitates extending a useful life of the stator vane assembly is described. The stator vane assembly includes a spacer and a vane secured to an engine casing. The bushing is between the spacer and vane, and prevents the spacer and the vane from contacting the engine casing. The bushing is fabricated from several materials formed in a matrix, such that at least a portion of the bushing is electrically conductive. During engine operation, a conductive path is realized through the bushing that discharges electrical charges.
