20090158703 | SLIDING RAMP NOZZLE SYSTEM FOR A GAS TURBINE ENGINE - A regulator system includes a slidable ramp intermediate a secondary flow path and a primary flow path of a gas turbine engine nozzle section. | 06-25-2009 |
20090241550 | Gas Turbine Engine Systems Involving Variable Nozzles with Flexible Panels - Gas turbine engine systems involving flexible panels are provided. In this regard, a representative flexible panel assembly for a gas turbine engine includes: a flexible panel operative to define at least one of a throat area and an exit area of a nozzle of a gas turbine engine, the panel being further operative to selectively exhibit a range of positions to regulate exhaust of the engine. | 10-01-2009 |
20090255269 | Gas Turbine Engine Systems Involving Variable Nozzles with Sliding Doors - Gas turbine engine systems involving variable nozzles with sliding doors are provided. In this regard, a representative door assembly for a gas turbine engine includes: a door configured for alignment with an exit area of a nozzle and operative to variably open and close the nozzle exit area such that gas directed along a gas path defined, at least in part, by the nozzle exit area is regulated | 10-15-2009 |
20090293498 | PIVOTING LINER HANGER - An example turbine engine assembly includes a first attachment structure secured to an engine casing or an engine liner. A second attachment structure is secured to the other of the engine casing or the engine liner. The assembly further includes a link having a rod portion extending longitudinally from a hemispherical end portion and terminating at a rod end portion. The hemispherical end portion is received within a recess defined by the first attachment structure. The rod end portion is secured relative to the second attachment structure to limit relative movement between the engine casing and the engine liner. | 12-03-2009 |
20130052006 | TIE ROD FOR A GAS TURBINE ENGINE - A tie rod includes a gusset which extends between a rod and a base. | 02-28-2013 |
20130125551 | RETRACTABLE EXHAUST LINER SEGMENT FOR GAS TURBINE ENGINES - A retractable exhaust liner segment between a gas turbine engine and an exhaust duct. | 05-23-2013 |
20130149098 | FAN BLADE TIP CLEARANCE CONTROL VIA Z-BANDS - An engine has a blade, a casing surrounding the blade, an seal ring, and a passive system for connecting the seal ring to the casing and for accommodating thermal expansion of the seal ring relative to the casing so as to maintain blade tip clearance control. The passive system may include at least one, metallic Z-band extending between the casing and the seal ring. | 06-13-2013 |
20150226125 | COMBINED HIGH PRESSURE TURBINE CASE AND TURBINE INTERMEDIATE CASE - A disclosed gas turbine engine includes a compressor section, a combustor section, a first turbine section and a second turbine section. An outer case structure for the gas turbine engine includes a single-piece case structure with a turbine case portion and a transition case portion. The transition case portion is integrally formed with the turbine case portion as a single part module. A combustor case houses the combustor and an aft turbine case supports the low pressure turbine. The outer case includes a forward end attachable to the combustor case and an aft end attachable to the aft turbine. | 08-13-2015 |
