20120304811 | GEARBOX MOUNT BRACKET - A bracket for attaching a gearbox to an engine casing has a first portion having a first array of openings for receiving attachments therethrough, the first portion having, on a backside thereof, a first rail for engaging a slot in the engine casing, and a second portion having a second array of openings for receiving attachments therethrough. A hookup for attaching to the gearbox attaches to and in between the first portion and the second portion for diminishing effects of radial rotation between the casing and the gearbox. | 12-06-2012 |
20130193298 | GAS TURBINE ENGINE MOUNTING STRUCTURE WITH SECONDARY LOAD PATH - A connection for mounting an aircraft engine to an aircraft pylon has a plate to be bolted to a portion of an aircraft engine, and a body extending rearwardly from the plate. The body has a main pivot attachment to a balance beam, which has thrust links pivotally attached to the balance beam. A back-up connection is included between the balance beam and the body such that the back-up connection allows normal pivoting movement of the balance beam relative to the body without contact at the back-up connection. | 08-01-2013 |
20130200211 | GAS TURBINE ENGINE MOUNTING STRUCTURE WITH SECONDARY LOAD PATHS - A connection for mounting an aircraft engine to an aircraft pylon includes a plate to be connected to a portion of an engine, and a body that extends rearward from the plate. A back-up connection, including a pin positioned within a slotted hole, is provided between the portion of the engine and the body. When there is a normal connection between the plate and the body, there is clearance between the pin and the slotted hole. | 08-08-2013 |
20130302157 | ADJUSTABLE ENGINE MOUNT - A forward engine mount assembly for a gas turbine engine includes a mount beam having a main body with a fore end and an aft end and a forward shackle assembly supported by the fore end of the mount beam. The forward shackle assembly comprises a first link configured to be connected to a first engine case structure and a second link configured to be connected to a second engine case structure. The first and second links are pivotally attached to each other. | 11-14-2013 |
20140061375 | ASSEMBLY FOR MOUNTING A TURBINE ENGINE TO A PYLON - An assembly for mounting a turbine engine to a pylon includes a mounting beam, a plurality of fasteners, a first mounting linkage and a second mounting linkage. The mounting beam includes a mount beam fitting that extends axially between a first mount beam end and a second mount beam end, and a mount beam flange that extends radially out from the mount beam fitting at the first mount beam end. A first fastener aperture extends radially through the mount beam fitting, and a second fastener aperture extends axially through the mount beam flange. The fasteners connect the mounting beam to the pylon. A first of the fasteners is mated with the first fastener aperture, and a second of the fasteners is mated with the second fastener aperture. The first mounting linkage connects the first mount beam end to a first engine attachment. The second mounting linkage connects the second mount beam end to second engine attachments. | 03-06-2014 |
20140061426 | SECONDARY LOAD PATH FOR GAS TURBINE ENGINE - A waiting link to support an engine on an aircraft includes a body portion including a first body portion opening, a second body portion opening, and a space therebetween. A first bearing is received in the first body portion opening and moveable in a generally vertical direction. A second bearing is received in the second body portion opening. The first and second bearings include a first and second bearing opening, respectively, that receives a first and second attachment member, respectively, that secures the body portion to a first and second structure, respectively. A cam is located in the space. The cam is pivotable between a first position and a second position. The waiting link does not provide a load path when the cam is in the first position, and when a primary load path fails, the waiting link provides the load path when the cam is in the second position. | 03-06-2014 |
20150369131 | AXIAL TENSION SYSTEM FOR A GAS TURBINE ENGINE CASE - A gas turbine engine includes a convex case section. The convex case section includes an upstream case portion having a first radius, a downstream case portion having a second radius, and an intermediate case portion between the upstream case portion and the downstream case portion. The intermediate case portion has a third radius larger than the first radius and the second radius. A tension rod extends from the upstream case portion to the downstream case portion. | 12-24-2015 |
20150375867 | Engine Mount Waiting Fail Safe Lug Joint with Reduced Dynamic Amplification Factor - An engine mount may include a clevis and a lug defining a hole therethrough. A pin may be joined to the clevis and may extend through the hole of the lug with the pin and the lug defining a clearance therebetween. A trigger system may be disposed on the lug and operatively associated with the pin. | 12-31-2015 |
