20130340440 | Machined Aerodynamic Intercompressor Bleed Ports - An air bleed system for a jet engine is provided. The air bleed system is located in the low pressure compressor chamber and comprises a movable bleed valve and a stationary, annular bleed case having a forward section and an aft section and ligaments connecting the two sections and providing structural support to the bleed case. The ligaments are machined from the bleed case into an aerodynamic shape that maximizes the flow of air through the bleed ports. | 12-26-2013 |
20130340555 | FOUR BAR BRACKET - A bracket for use with a four bar linkage, has a head portion having a triangular shape, and a shank extending from a corner of the triangular head portion, the shank thickening depthwise and narrowing widthwise along its length. | 12-26-2013 |
20130341547 | FOUR BAR DRIVE MECHANISM FOR BLEED SYSTEM - An actuation system for a bleed valve includes first and second bell cranks connected by a connecting link. The first bell crank has a first arm that is coupled to a bleed valve and a second arm that is coupled to the connecting link. The connecting link has a first end coupled to the second arm of the first bell crank and a second end coupled to a first arm of the second bell crank. A second arm of the second bell crank is coupled to an actuating element. Input is communicated through the actuating element to move the bleed valve between open and closed positions via the first and second bell cranks. | 12-26-2013 |
20130341875 | BULB SEAL WITH METAL BACKED FASTENER - A seal for use with a duct has a body having a partially circumferential shape, a bulb extending from the body and extending circumferentially with the body, and a reinforcement strip disposed in the body. | 12-26-2013 |
20130343876 | SPHERICAL-LINK END DAMPER SYSTEM WITH NEAR CONSTANT ENGAGEMENT - A link includes a link body with two ends, a ring bore with a ring bore axis and a bearing, a mount bore with a mount bore axis and a bearing. The link also has an end curvature at the end having the ring bore wherein the curvature axis is substantially perpendicular to the ring bore axis. | 12-26-2013 |
20130343883 | TWO-PIECE DUCT ASSEMBLY - A duct assembly for venting flow from an internal portion of a gas turbine engine, has a first piece having a first duct portion extending therethrough, the first piece configured to withstanding backbone loads of the engine, the first piece having a first portion of a duct passing therethrough, and a second piece, the second piece having a second portion of the duct passing therethrough, the second portion and the first portion aligning, the second piece constructed of a lighter material than the first piece. | 12-26-2013 |
20140050567 | SYNCHRONIZING RING SURGE BUMPER - A bumper assembly includes a bracket and a pad. The pad is connected to the bracket by a first rivet. Additionally, a synchronizing ring assembly for a gas turbine engine includes a ring section and a bumper assembly. The bumper assembly is connected to a side surface of the ring section and extends axially adjacent an inner radial surface of the ring. The bumper assembly is disposed adjacent a gap at an end of the ring section. | 02-20-2014 |
20140093375 | REDUCED HEIGHT LIGAMENTS TO MINIMIZE NON-INTEGRAL VIBRATIONS IN ROTOR BLADES - A system for minimizing non-integral vibrations in rotor blades located in a compressor section of a gas turbine engine includes a casing having a plurality of bleed slots, at least one of the bleed slots being located in close proximity to a row of rotor blades, a plurality of structural ligaments, at least one of the structural ligaments extending between two adjacent ones of the bleed slots; and a channel for reducing the height of at least one of the structural ligaments so as to minimize the non-integral vibrations in the rotor blades in the row. | 04-03-2014 |
20140234082 | BUMPER FOR SYNCHRONIZING RING OF GAS TURBINE ENGINE - A synchronizing assembly for a gas turbine engine has a synchronizing ring. A bumper assembly has a cradle and a bumper held within the cradle. The cradle is secured to the synchronizing ring by at least one fastener without the fastener extending through the bumper. An engine is also disclosed. | 08-21-2014 |
20150027130 | SPLIT RING VALVE - A valve includes a body with bleed ports and a ring. The ring surrounds the body and includes two adjacent ring segments. The ring is movable between an open position and a closed position, the latter of which prevents flow through the ports. | 01-29-2015 |
