    Abstract: A sensor assembly includes a wear sensor and a seal member. The wear sensor has an encapsulation body with a wear face, a sacrificial conductor embedded within the encapsulation body and spaced apart from the wear face, and a monitoring lead extending into the encapsulation body and connected to the sacrificial conductor. The wear sensor is fixed relative to the seal member and the encapsulation body has a wear coefficient that is greater than a wear coefficient of the seal member. Bearing arrangements and methods of monitoring seal wear in bearing arrangements are also described.

    Abstract: According to one embodiment, an air turbine starter is provided. The air turbine starter comprising: a turbine wheel including a hub integrally attached to a turbine rotor shaft and a plurality of turbine blades extending radially outward from the hub; an inlet housing at least partially surrounding the turbine wheel; a nozzle located upstream from the turbine wheel and contained within the inlet housing defining an inlet flowpath between the nozzle and the inlet housing, the inlet flowpath directs air flow into the turbine blades; and a plurality of turbine vanes rotatably connected to the nozzle, each turbine vane extending radially from the nozzle into the inlet flowpath towards the inlet housing; wherein the plurality of turbine vanes are operable to adjust air flow through the inlet flowpath by rotating each turbine vane.

    Abstract: An example arrangement for cooling a gas turbine engine includes an air turbine starter having a turbine section for rotationally driving a compressor through rotation of a shaft. An starter air valve is configured to control a flow of pressurized air that flows downstream towards turbine blades of the air turbine starter. An airflow adjustment device (AAD) is configured to adjust the flow when a manual override feature of the starter air valve is engaged based on a rotational speed of one of the shaft and an additional shaft that is driven by the compressor. A governor is configured to control a degree to which the AAD adjusts the flow. The governor is mechanically linked to the shaft through one or more gears and configured to adjust the AAD such that a rotational speed of said one the shafts does not exceed a predefined threshold during a particular operating mode.

    Abstract: A bearing carrier is provided. The bearing carrier including: a bearing body of a first material having a shaft-receiving aperture and a bridge land with a finger cut to channel fluid pressurized by intermeshing of gears rotatably supported by the bearing carrier into an outlet defined by a housing enveloping the bearing carrier, wherein the bearing body includes a bearing face configured to be in a facing spaced relationship with the gears, wherein the bearing face includes a second material integral with the first material, wherein at least one of the first material and the second material define a portion of the bearing face of the bearing body extending about the shaft-receiving aperture, the portion of the bearing face excluding the bridgeland.

    Abstract: A seal housing with fluid regulating capability is provided for use with an outlet. The seal housing includes a seal element, a fitting and a valve. The seal element includes an angled flange that is fittable to the outlet and a seal element body from which the angled flange extends. The seal element body defines a bore extending between opposite open ends of the body and receptive of fluid from the outlet. The fitting is configured to tightly engage with the outlet and to urge the angled flange against the outlet with increasing pressure as fitting-outlet engagement proceeds. A valve is constrained within the bore and configured to regulate a flow of the fluid, which is received from the outlet, through the bore.
