Abstract: A monolithic engine assembly may include an engine body that includes a regenerator body. The engine body and the regenerator body may respectively define at least a portion of a monolithic body, or the engine body may define at least a portion of a first monolithic body-segment and the regenerator body may define at least a portion of a second monolithic body-segment operably coupled or operably couplable to the first monolithic body-segment. The regenerator body may include a regenerator conduit, and a plurality of fin arrays adjacently disposed within the regenerator conduit and respectively supported by the regenerator conduit in spaced relation to one another. The spaced relation of the plurality of fin arrays may define a gap longitudinally separating adjacent ones of the plurality of fin arrays.

Abstract: A system including a closed cycle engine having a piston body defining a hot side and a cold side and having a piston assembly movable within the piston body. An electric machine is operatively coupled with the piston assembly. A control system includes one or more sensors operable to detect a piston movement characteristic of the piston assembly movable within the piston body. A controller is communicatively coupled with the one or more sensors and a controllable device. The controller is configured to determine a control command based at least in part on data received from the one or more sensors. The control command is selected based at least in part to cause the electric machine operatively coupled with the piston assembly to generate a preselected electrical power output. The controller provides the determined control command to the controllable device. The controllable device is operable to control an input to an engine working fluid disposed within the piston body.

Abstract: A monolithic heat exchanger body includes a plurality of heating walls and a plurality of combustion fins. The plurality of heating walls are configured and arranged in an array of spirals or spiral arcs relative to a longitudinal axis. Adjacent portions of the plurality of heating walls respectively define a corresponding plurality of heating fluid pathways therebetween. The plurality of combustion fins are circumferentially spaced about a perimeter of an inlet plenum. The inlet plenum includes or fluidly communicates with a combustion chamber. The plurality of heating fluid pathways fluidly communicate with the inlet plenum. The plurality of combustion fins occupy a radially or concentrically inward portion of the monolithic heat exchanger body. The plurality of heating fluid pathways have a heat transfer relationship with a heat sink disposed about a radially or concentrically outward portion of the monolithic heat exchanger body. A plurality of conduction breaks disposed radially or concentrically outward relative to the plurality of combustion fins at least partially inhibit heat conduction from the plurality of combustion fins to the plurality of heating walls.

Abstract: An electric machine includes at least one rotor module. A rotor module includes a rotor hub having a hub body, and a plurality of first protrusions and a plurality of second protrusions. One or more first protrusions include an elongated portion and a head portion. One or more second protrusions include a wedge-shaped profile. The rotor module further includes a magnetic core having a plurality of core members disposed on the rotor hub. A core member of the plurality of core members is disposed such that the head portion of the first protrusion located between the adjacent second protrusions engages with the core member, and each of the one or more second protrusions extends at least partially in a space between adjacent core members of the plurality of core members. Moreover, the rotor module includes a permanent magnet disposed in a space between the adjacent core members.

Abstract: A method of operating a rotary machine. The method includes rotating a rotor; receiving current at at least one electromagnetic bearing supporting the rotor; detecting an operating characteristic of the rotary machine; determining, using a controller, an operating state of the rotary machine based on the detected operating characteristic; retrieving operating modes stored in a memory of the controller, the operating modes including a normal operating mode and a fault tolerant operating mode; switching between the normal operating mode and the fault tolerant operating mode, using the controller, based on the determined operating state of the rotary machine; regulating, using the controller, at least one of a magnetic force and a position of the at least one electromagnetic bearing; and regulating, using the controller, at least one of a position and an opening of at least one fluid flow control device.

Abstract: An electric pump powered by an electric motor having a stator disposed within a hollow rotor is provided. Impellers on the rotor outer surface extend into a fluid flow path defined by the pump. One or more torque-producing rotor sections are driven by a plurality of independently controllable stator sections disposed within the rotor cavity. The relative positions of the rotor and stator are maintained by a plurality of bearings configured to allow rotation of the rotor and defining a bearing span. The pump is configured such that the stator and rotor share the same bearing span. Such an arrangement reduces motor windage losses relative to conventional motors in which the rotor is disposed within the stator, owing to a reduction in the diameter of the air gap between the stator and the rotor. In addition, the peripheral speed of the pump is increased owing to an increase in the rotor diameter.
