20090049837 | GAS TURBINE ENGINE AIR VALVE ASSEMBLY - A gas turbine engine air valve assembly has first and second valving elements. The second element is rotatable about a first axis relative to the first element. The rotation controls a flow of air through the first and second elements. An actuator is coupled by a linkage to the second element. A plurality of follower member assemblies each have an insertion portion extending through a corresponding first aperture in the first valving element and a corresponding second aperture in the second element. The insertion portion is circumferentially fixed relative to one of the first and second valving elements and circumferentially moveable relative to the other of the first and second valving elements. | 02-26-2009 |
20090272123 | Gas Turbine Engine Systems and Related Methods Involving Thermally Isolated Retention - Gas turbine engine systems and related methods involving thermally isolated retention are provided. In this regard, a representative method for attaching a gas turbine engine component includes using a fastener, varying in diameter along a length thereof, to prevent a portion of a component from being crimped between surfaces to which the component is attached such that the component moves relative to the surfaces responsive to thermal cycling of a gas turbine engine of which the surfaces and the component are constituent parts. | 11-05-2009 |
20110120084 | GAS TURBINE ENGINE AIR VALVE ASSEMBLY - A gas turbine engine air valve assembly has first and second valving elements. The second element is rotatable about a first axis relative to the first element. The rotation controls a flow of air through the first and second elements. An actuator is coupled by a linkage to the second element. The linkage includes a spindle having a first portion coupled to the actuator to rotate the spindle about a second axis. A guided spherical bearing couples a second portion of the spindle to the second element. | 05-26-2011 |

20130091849 | AUGMENTOR SPRAY BAR WITH TIP SUPPORT BUSHING - An augmentor for a gas turbine engine includes an augmentor spray bar with a spray bar outlet, and an augmentor spray bar tip. The spray bar tip includes a tip body, a tip bushing and a tip support strut. The tip body includes a first flow passage extending therethrough between a tip inlet and a tip outlet, wherein the tip inlet is connected to the spray bar outlet. The tip bushing includes a bushing bore. The tip body extends through the bushing bore defining a second flow passage between the tip body and the tip bushing. The tip support strut connects the tip body to the tip bushing across the second flow passage. | 04-18-2013 |
20130139512 | LEAF SPRING DAMPER FOR A TURBINE ENGINE FUEL DELIVERY SYSTEM - A turbine engine fuel delivery system includes a mounting platform, a spray bar assembly and a leaf spring damper with a stack of a plurality of leaf springs. The stack includes a base segment connected longitudinally between a first spray bar contact segment and a second spray bar contact segment. The base segment is connected to the mounting platform and is located a first distance from the spray bar assembly. The first spray bar contact segment engages the spray bar assembly and is located a second distance from the mounting platform. The second spray bar contact segment engages the spray bar assembly and is located a third distance from the mounting platform. | 06-06-2013 |
20150252729 | INNER DIFFUSER CASE STRUTS FOR A COMBUSTOR OF A GAS TURBINE ENGINE - An inner diffuser case for use in a combustor of a gas turbine engine includes a multiple of struts across an annular flow path between an outer shroud and an inner shroud, at least one of the multiple of struts is an open strut. | 09-10-2015 |
