Abstract: An aspect of the present disclosure is directed to a system for energy conversion. The system includes a closed cycle engine containing a volume of working fluid. The engine includes an expansion chamber and a compression chamber each separated by a piston attached to a connection member of a piston assembly. The engine further includes a plurality of heater conduits extended from the expansion chamber. The engine includes a plurality of chiller conduits extended from the compression chamber. The expansion chamber and heater conduits are fluidly connected to the compression chamber and chiller conduits via a walled conduit.

Abstract: A nested segment assembly and a method of additively manufacturing the same are provided. In one example aspect, the nested segment assembly includes a first component segment and a segment component segment positioned adjacent the first component segment. The first component segment has an end face and a tongue projecting outwardly from the end face. The second component segment defines a groove. The groove is defined at an end face of the second component segment that is adjacent the end face of the first component segment. The first component segment and the second component segment are additively printed such that at least a portion of the tongue of the first component segment is nested within the groove defined by the second component segment. Segmented components having a tesla valve formed therebetween are also provided.

Abstract: A combustor assembly for a gas turbine engine and a method of additively manufacturing the same are provided. A combustor dome includes a combustor wall defining a hole and a circumferential groove defined within the combustor wall around the hole. A floating ferrule assembly is additively manufactured with the combustor dome and includes a ferrule positioned at least partially within the hole and defining a radial lip that is received within the circumferential groove to inseparably position the ferrule within the combustor wall. A build support arm is attached to the ferrule by a frangible connecting member, the frangible connecting member being breakable for separating and removing the build support arm from the ferrule.

Abstract: The present disclosure is directed to a gas-lubricated bearing assembly for a gas turbine engine and method of damping same. The bearing assembly includes a bearing pad for supporting a rotary component and a bearing housing attached to or formed integrally with the bearing pad. The bearing housing includes a first fluid damper cavity, a second fluid damper cavity in restrictive flow communication with the first fluid damper cavity via a restrictive channel configured as a clearance gap, and a damper fluid configured within the first and second fluid damper cavities. More specifically, the damper fluid of the present disclosure is configured to withstand the high temperature environment of the engine. Thus, the bearing housing is configured to transfer the damper fluid from the first fluid damper cavity to the second fluid damper cavity via the restrictive channel in response to a force acting on the bearing pad.

Abstract: A bearing includes a bearing pad for supporting a rotary component and a housing attached to or formed integrally with the bearing pad. The housing includes a flexible column extending towards the bearing pad for providing the bearing pad with an airflow. The column supports the bearing pad from a location inward of an outer periphery of the bearing pad along an axial direction of the bearing. With such a configuration, a resistance of the bearing pad along a radial direction of the bearing is less at the outer periphery than a resistance of the bearing pad along the radial direction proximate the column.

Abstract: A bearing including a bearing pad and a housing is provided. The bearing pad has a thrust face for supporting a vibration along an axial direction of the bearing. Additionally, the housing is formed integrally using an additive manufacturing process and is attached to or formed integrally with the bearing pad. The housing defines a working gas delivery system for providing a flow of pressurized working gas to the thrust face of the bearing pad and a fluid damper cavity. The fluid damper cavity provides a dampening of the axial vibration supported by the thrust face of the bearing pad along the axial direction.
