Abstract: According to an aspect, a system for a gas turbine engine includes a reduction gear train operable to drive rotation of a starter gear train that interfaces to an accessory gearbox of the gas turbine engine. The reduction gear train includes a starter interface gear that engages the starter gear train and a core-turning clutch operably connected to the starter interface gear. The reduction gear train also includes a geared rotary actuator including a primary planetary gear system, where the geared rotary actuator is operably connected to the core-turning clutch. The reduction gear train further includes a secondary planetary gear system operably connected to the primary planetary gear system and a core-turning input. The system also includes a mounting pad with an interface to couple a core-turning motor to the core-turning input of the reduction gear train.

Abstract: A method of assembling a bearing assembly includes fitting a first ring onto a first end of a gear shaft. A second ring is fed into a slot in the first ring. The second ring is driven through the slot in the first ring. The second ring is positioned within the first ring. The second ring is positioned about the gear shaft such that a first end and a second end of the second ring are covered by a solid portion of the first ring.

Abstract: An air turbine starter includes a transfer tube having a lubrication inlet and a lubrication outlet configured to allow fluid to flow therethrough. A valve is positioned within the transfer tube including a spring. The spring is configured to selectively allow fluid flow within the transfer tube based on fluid pressure differential across the valve. The spring can have three positions: a first position configured to prevent flow within the transfer tube, an intermediate position configured to allow free flow of fluid within the transfer tube, and a compressed positioned to prevent flow to the lubrication outlet.

Abstract: A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.
