摘要： An assembly (20) is provided for a gas turbine engine (136). This engine assembly (20) includes a gas turbine engine case (30), a conduit (24) and a bushing (26). The gas turbine engine case (30) includes a case wall (36) and a boss (38) at a port (66) through the case wall (36). The conduit (24) extends longitudinally along a centerline (60) through the port (66) and into an interior of the gas turbine engine case (30). The bushing (26) circumscribes the conduit (24) and is arranged within the port (66). The bushing (26) is engaged with and laterally between the conduit (24) and the boss (38). The bushing (26) is configured from or otherwise includes a cellular material (120). The cellular material (120) may be or otherwise include a cellular metal material and/or a cellular composite material.

摘要： A health parameter for the aircraft engine (110) is monitored by a health evaluation device (240), the health parameter received from a first instrument (230). The health parameter is compared, by the health evaluation device (240), to a predetermined threshold. When the health parameter reaches the predetermined threshold, the health evaluation device wirelessly transmits a fault signal to a controller (210) associated with the aircraft engine (110) to elicit a health response from the controller (210), the fault signal containing at least two mutually-exclusive fault codes associated with an operating condition of the aircraft engine (110) monitored by a second instrument (220).

摘要： An assembly (20) is provided for a turbine engine. This turbine engine assembly includes a stationary structure (24), a rotating structure (22), a bearing (26). The rotating structure (22) rotatable about an axis (28) relative to the stationary structure (24). The bearing (26) supports the rotating structure (22). The stationary structure (24) includes a flexible bearing support (50) and a crushable bumper (54). The flexible bearing support (50) supports the bearing (26). The crushable bumper (54) is arranged radially outward of and axially overlaps the flexible bearing support (50). The stationary structure (24) is configured such that: the flexible bearing support (50) is disengaged from the crushable bumper (54) during a first mode of operation; and the flexible bearing support (50) contacts the crushable bumper (54) during a second mode of operation.
