Abstract: A seal assembly for use in a gas turbine engine includes a first component, a second component, and a sealing unit. The first component is spaced apart from the second component to form a gap therebetween. The sealing unit is positioned in the gap between the first and second components to block liquids and/or gasses from traveling through the gap.

Abstract: An aircraft powerplant having a shaft is disclosed in one embodiment in which a squeeze-film damper is used. The squeeze-film damper includes a plurality of sectors having a working fluid. A pressure can be controlled in the working fluid to the sectors to discourage changes in the sectors as a result of vehicle maneuvering. A controller is used to operate upon sensed aircraft motion and regulate pressure in the sectors.

Abstract: A fluid sealing assembly includes a shaft and a seal. The shaft includes a surface portion having a microstructural geometry. The seal has a radially flexible portion disposed in proximity to the surface portion having the microstructural geometry such that when the shaft is rotated a pressure differential is generated at the interface of the seal and the surface portion having the microstructural geometry that pushes or pulls fluid relative to the interface.

Abstract: A rotor assembly includes an oil jet assembly, an inner shaft assembly, an outer shaft assembly, and an oil mist shield. The oil jet assembly selectively ejects oil for lubrication. The inner shaft assembly is configured to rotate about a central axis. The outer shaft assembly is configured to rotate selectively about the central axis independent of the inner shaft assembly. The oil mist shield is coupled with the outer shaft and is configured to selectively block and allow the oil from the oil jet assembly from passing into a cavity.
