Abstract: A method for shimming a thrust bearing for an accessory power take off shaft to obtain optimal meshing of bevel gears within the internal gearbox (IGB) without disassembly of the IGB is enabled by relocating the thrust bearing from the engine sump. The accessory gearbox (AGB) is driven from a power off-take from the turbine spool via the IGB. The radial position of the power take-off bevel gear is established by a radial position of the thrust bearing attached to the exterior of the casing via a housing. Candidate shims are selected from a set each having different thicknesses, the shims are formed of two halves and placed between the housing and the engine casing to adjust the radial position of the thrust bearing and consequently the power take-off bevel gear, without requiring the disassembly of the IGB.

Abstract: A system includes an air chamber and an oil capture cavity. The air chamber includes an inlet to receive pressurized air from a gas turbine engine. The oil capture cavity is positioned between the air chamber and an oil sump supplying lubricating oil to the gas turbine engine. The oil capture cavity includes an auxiliary vent formed in a base of the oil capture cavity. A seal may separate the oil capture cavity from fluid communication with the oil sump. A nozzle provides fluid communication between the oil capture cavity and the air chamber. The nozzle is configured and positioned to direct a stream of the pressurized air into the oil capture cavity against an opposite wall of the oil capture cavity to create a quiescent zone at the base of the oil capture cavity. The quiescent zone includes the auxiliary vent.

Abstract: A strut may include an outer tube including an outer tube first end, an outer tube second end, and a longitudinal axis extending from the outer tube first end to the outer tube second end. The outer tube may define an interior. The strut also may include an additively manufactured inner tube at least partially within the interior of the outer tube of the strut. The additively manufactured inner tube defines an additively manufactured inner tube first end and an additively manufactured inner tube second end. The additively manufactured inner tube first end is integrally joined to the outer tube proximate to the outer tube first end.
