20120107124 | AIRFOIL ATTACHMENT ARRANGEMENT - An example airfoil retention arrangement includes a retention assembly having a first retention segment and a second retention segment. Each of the retention segments is separately moveable to an installed position relative to an airfoil assembly and a support structure. The retention segments each have a portion position between a lip of the airfoil assembly and a collar of the support structure when the retention segments are in the installed position. The retention assembly is configured to limit radial movement of an airfoil relative to the support structure when in the installed position. | 05-03-2012 |
20130001319 | IMPINGEMENT COOLED NOZZLE LINER - A nozzle liner for a rotatable nozzle includes a seal land and a rotatable seal for moving with the nozzle. The seal has a first diffusion hole for distributing cooling air if the rotatable seal is in a first position and a second diffusion hole for distributing cooling air if the rotatable seal is in a first position and if in a second position. | 01-03-2013 |
20130115079 | TIE-ROD NUT INCLUDING A NUT FLANGE WITH A PLURALITY OF MOUNTING APERTURES - A tie-rod nut includes a nut base that extends between a first nut end and a second nut end, and a nut flange that extends radially outwards from the nut base at the first nut end. The nut base includes a nut bore with a threaded bore region that extends axially from the second nut end towards the first nut end. The nut flange includes a plurality of mounting apertures that are arranged circumferentially around the nut base. The nut flange may be connected to a substrate by a fastener that extends through a first one of the plurality of mounting apertures. | 05-09-2013 |
20130224010 | TURBINE FRAME FAIRING FOR A GAS TURBINE ENGINE - A static structure of a gas turbine engine includes a multiple of airfoil segments and at least one structural reinforcement ring mounted to the multiple of airfoil segments. | 08-29-2013 |
20130259646 | Dual-Intent Locator Pin and Removable Plug for Gas Turbines - A borescope plug configuration is disclosed. The borescope plug configuration comprises an inspection path defined through a bore in a first engine structure, a second engine structure, and an opening into the gas path of an engine. The borescope plug configuration further comprises a removable plug for sealing the inspection path. The removable plug is adapted to couple the first engine structure to the second engine structure. | 10-03-2013 |
20140013769 | MID-TURBINE FRAME WITH OIL SYSTEM MOUNTS - A gas turbine engine includes a combustor, a first turbine section in fluid communication with the combustor, a second turbine section in fluid communication with the first turbine section, and a mid-turbine frame located axially between the first turbine section and the second turbine section. An oil system includes a first oil system component that houses oil. A first connector mechanically connects the first oil system component to the mid-turbine frame. | 01-16-2014 |
20140013770 | VANE INSERTABLE TIE RODS WITH KEYED CONNECTIONS - A gas turbine engine includes a combustor, a first turbine section in fluid communication with the combustor, a second turbine section in fluid communication with the first turbine section, and a mid-turbine frame located axially between the first turbine section and the second turbine section. The mid-turbine frame includes a first frame case, a second frame case, a vane positioned between the first frame case and the second frame case, and a spoke extending through the vane and connecting the first frame case to the second frame case. The spoke includes a tie rod having a first end connected to the first frame case at a keyed connection. | 01-16-2014 |
20140013771 | MID-TURBINE FRAME WITH THREADED SPOKES - A mid-turbine frame located in a gas turbine engine axially aft of a high-pressure turbine and fore of a low-pressure turbine includes an outer frame case, an inner frame case, and at least a first spoke connecting the outer frame case to the inner frame case. The first spoke includes a tie rod having a first threaded surface and a connector having a second threaded surface. The first and second threaded surfaces overlap partially but not completely. | 01-16-2014 |
20140056704 | TURBINE ENGINE SUPPORT ASSEMBLY INCLUDING SELF ANTI-ROTATING BUSHING - A turbine engine includes multiple tierod supports. Each of the tierod supports is connected to an inner frame case of the turbine engine via multiple fasteners and at least one self anti-rotating bushing component. | 02-27-2014 |
20140093368 | OUTER CASE WITH GUSSETED BOSS - An outer case employed in a gas turbine engine includes a plurality of support member bosses and a plurality of gusseted bosses. The plurality of support member bosses are disposed circumferentially around the outer case for receiving and securing support members that attach the outer case to an inner hub. The plurality of gusseted bosses are disposed circumferentially around the outer case and between the plurality of support member bosses. | 04-03-2014 |
20140102110 | MID-TURBINE FRAME WITH TENSIONED SPOKES - A mid-turbine frame located in a gas turbine engine axially aft of a high-pressure turbine and fore of a low-pressure turbine includes an outer frame case, an inner frame case, and at least a first spoke connecting the outer frame case to the inner frame case. The first spoke is tightened so as to be in tension during substantially all operating conditions of the gas turbine engine. | 04-17-2014 |
