Abstract:
Gas turbine engine systems involving fairings with locating data are provided. In this regard, a representative a fairing assembly for a gas turbine engine includes: a first locating component having a leading edge, first and second sides extending from the leading edge, and a recess oriented parallel to the leading edge, the recess having a first datum surface, the first locating component being operative to be positioned between a portion of a strut and a portion of an interior surface of a fairing sheath such that the first datum surface establishes a desired orientation of the fairing sheath relative to the strut.
Abstract:
A composite airfoil includes a woven preform with warp yarns of a first material, the preform with a tip, root, leading edge, trailing edge and an intermediate region positioned between the root and the tip; and a first matrix made of a first resin maintaining the relative positions of the preform yarns. The composite blade further includes at least one of: fill yarns of a second material in the woven preform; and a second matrix made of a second resin maintaining the relative positions of the preform yarns in a portion of the airfoil.
Abstract:
A method of loading and locking a plurality of tangential rotor blades is provided. The method includes the steps of providing a disk having a slot and a pair of rails adjacent the slot, positioning a first snap seal in a desired location over the slot and the rails, radially loading a first blade having a platform into the slot and rotating the blade, and positioning the first blade adjacent the snap seal so that a portion of the snap seal slides under the platform. The rotor blades preferably have an attachment part which comprises a circular neck and a dovetail portion having two ends and upper and lower chamfered edges at each of the ends.
Abstract:
The system has a shim (38) for defining a gap between a bumper pad and a bumper (32). A pin (36) prevents rotation of the bumper relative to a synchronizing ring and a fastener (30) e.g. screw or bolt fully traps the shim. The fastener includes a thread at one end and passes through a bore in the bumper and through a hole in the ring. The fastener has a sleeve (34) passing through the ring.
Abstract:
An airfoil having a composite blade formed from a plurality of plies and having a leading edge and a root for attachment to an engine. The blade has a decreased number of plies at the junction of the blade leading edge and the root. A metallic sheath is attached to the leading edge, wherein the sheath has a portion proximate the junction of sufficient thickness to restore at least a portion of the decreased number of plies.(Figure 1)

Abstract:
The present invention relates to a bumper system for use with a compressor variable vane system. The bumper system broadly comprises a synchronizing ring, a bumper, a shim for defining a gap between a bumper pad and the bumper, a pin for preventing rotation of the bumper relative to the synchronizing ring, and a device for fully trapping t he shim. In a first embodiment, the device for fully trapping the shim comprises a sleeve passin g through the synchronizing ring. In a second embodiment, the device for fully trapping th e shim comprises a pin which passes through the synchronizing body. In a third embodiment, the device for fully trapping the shim comprises a fastener with a shoulder.
