Abstract: An integrated inducer heat exchanger is provided. The integrated inducer heat exchanger includes multiple airfoil devices disposed in an annular array within an inner circular casing and an outer circular casing forming multiple passages for allowing a flow of fluid from a forward side to an aft side of the integrated inducer heat exchanger. The integrated inducer heat exchanger also includes multiple annular manifolds arranged about the outer circular casing configured for supplying a flow of coolant at low temperature from one or more coolant sources and returning the flow of coolant at high temperature to the one or more coolant sources via an external heat exchanger for dissipating heat and multiple transfer tubes connecting the multiple annular manifolds with the multiple airfoil devices for transferring the flow of coolant within the airfoil devices for exchanging heat between the coolant and the fluid passing through the multiple passages.

Abstract: A heat exchanger is provided that can include furcating unit cells coupled with each other. Each of the unit cells can be elongated along an axis and include a sidewall that defines annular ring openings on opposite ends of the unit cell along the axis. The sidewall also can define undulating annular rings between the annular ring openings and axially separated from each other along the axis. The sidewall can further define angled openings into the unit cell both above and below each of the undulating annular rings. At least a first opening of the annular ring openings and the angled openings can be configured to be an inlet to receive a first fluid into the unit cell and at least a second opening of the annular ring openings and the angled openings configured to be an outlet through which the first fluid exits the unit cell.

Abstract: A thermal management system for transferring heat between fluids includes a thermal transport bus through which a heat exchange fluid flows. Additionally, the system includes a heat source heat exchanger arranged along the bus such that heat is added to the fluid flowing through the heat source heat exchanger. Moreover, the system includes a plurality of heat sink heat exchangers arranged along the bus such that heat is removed from the fluid flowing through the plurality of heat sink heat exchangers. Furthermore, the system includes a bypass conduit fluidly coupled to the bus such that the bypass conduit allows the fluid to bypass one of the heat source heat exchanger or one of the heat sink heat exchangers. In addition, the system includes a valve configured to control a flow of the fluid through the bypass conduit based on a pressure of the fluid within the bus.

Abstract: A system configured for operation below a threshold temperature system includes a power supply, a housing, a temperature-sensitive electronic component, and a heating circuit. The temperature-sensitive electronic component is enclosed within said housing and electrically connected to the power supply, wherein the temperature-sensitive electronic component becomes susceptible to failure when the temperature of said temperature-sensitive electronic component decreases and crosses the threshold temperature. The heating circuit is at least partially enclosed within the housing and comprising a temperature-dependent resistor, the heating circuit electrically connected to the power supply and configured to generate heat energy within the housing when the temperature within the housing decreases and approaches the threshold temperature in order to maintain the temperature of the temperature-sensitive electronic component above the threshold temperature.

Abstract: A tip for a turbine component, turbine rotor blade or tip of a blade, is disclosed. The tip includes a tip plate configured to be coupled at a tip end of an airfoil chamber; and a tip rail extending radially from the tip plate, the tip rail disposed near or at a periphery of the tip plate. The trip rail includes a cooling structure constituting at least a portion of the tip rail. The cooling structure is in fluid communication with the airfoil chamber, and includes a plurality of repeating, three dimensional unit cells. Each unit cell defines a flow passage that is in fluid communication with the flow passage of at least one other unit cell. The flow passages of the 3D unit cells create a tortuous cooling passage in at least a portion of the tip rail.

Abstract: A recuperator includes a monolithic heat exchanger core having a first side proximal to a combustor inlet and a turbine outlet, and a second side that includes an exhaust outlet. A compressed air inlet is located on the second side, and a compressed air outlet is located on the first side. The compressed air outlet supplies air to a combustor. A first plurality of passageways connects the compressed air inlet to the compressed air outlet. A turbine exhaust inlet is located on the first side, and a turbine exhaust outlet is located on the second side. A second plurality of passageways connects the turbine exhaust inlet to the turbine exhaust outlet. The first and second plurality of passageways are defined by parting plates that extend radially outward in a spiral pattern that maintains a substantially equal distance between adjacent parting plates.
