Abstract: A heat exchange system for a gas turbine engine includes a first heat exchanger that defines a first heat source flowpath, a second heat exchanger that defines a second heat source flowpath, and a coolant fluid circuit. The coolant fluid circuit defines a first coolant flowpath that extends through the first heat exchanger and is in thermal communication with the first heat source flowpath, and a second coolant flowpath that extends through the second heat exchanger and is in thermal communication with the second heat source flowpath. The first coolant flowpath and the second coolant flowpath are arranged in a parallel flow configuration.

Abstract: A gas turbine engine defines a working air flowpath and includes an electrical system having an electric machine coupled to the rotary component at least partially inward of the working air flowpath along the radial direction and an electric bus electrically coupled to the electric machine. The electric bus includes an electric line extending through the working air flowpath within or downstream of a turbine section. The engine further includes a cooling system including a cooling fluid supply line and a cooling fluid return line, wherein a portion of the electric line extending though the working air flowpath is substantially embedded within the cooling fluid supply line, and wherein a portion of the cooling fluid supply line extending though the working air flowpath is substantially embedded within the cooling fluid return line.

Abstract: A heat transfer system includes a heat exchanger located at least partially within a coolant flowpath. The heat exchanger defines at least in part a first flowpath and a second flowpath, the first flowpath configured to be in fluid communication with the coolant flowpath, and the second flowpath configured to receive a flow of a motive fluid. The heat transfer system further includes a throttling device that is in fluid communication with the second flowpath of the heat exchanger. The heat exchanger receives at least a portion of the flow of the motive fluid from the heat exchanger. The throttling device is also in fluid communication with the coolant flowpath at a location upstream of the heat exchanger for providing the flow of motive fluid to the coolant flowpath at the location upstream of the heat exchanger.

Abstract: Flow paths and boundary layer restart features are provided. For example, a flow path comprises a flow path wall defining an inner flow path surface and an asymmetric notch defined in the flow path wall. The asymmetric notch comprises a first surface and a second surface and is asymmetric about a first line extending through an intersection of the first and second surfaces. Further, a flow boundary layer restart feature comprises a first surface extending inward with respect to a flow path surface of a flow path and a second surface extending inward with respect to the flow path surface. The second surface is asymmetric with respect to the first surface such that the first and second surfaces define an asymmetric notch. Additionally, a flow path wall may comprise an asymmetric notch that includes a flow expansion angle and a flow contraction angle that are unequal.
