    Abstract: A system for cooling aircraft components includes a compressor configured to receive air bled from a gas turbine engine and compress the received air. Additionally, the system includes a heat exchanger configured to receive the compressed air from the compressor and cool the compressed air; a turbine configured to receive the cooled air from the heat exchanger, with the cooled air expanding as the cooled air flows through the turbine. Furthermore, the system includes a defroster configured to receive the expanded air from the turbine, with the defroster further configured to capture frozen particulate matter from the expanded air. As such, at least a portion of the cooled air from the heat exchanger is routed to the defroster to melt the captured frozen particulate matter.

    Abstract: A method is provided for operating a hybrid-electric propulsion system of an aircraft. The hybrid-electric propulsion system includes a gas turbine engine having a high pressure system, a low pressure system, an electric machine coupled to at least one of the high pressure system or low pressure system, and an energy storage unit. The method includes operating the electric machine as an electric generator to charge the energy storage unit during a flight operation of the aircraft; switching the gas turbine engine to an electric operating mode during or after a landing operation of the aircraft; driving a system of the gas turbine engine using power from the energy storage unit while in the electric operating mode to provide or assist with providing ground operations the aircraft.

    Abstract: An aspect of the present disclosure is directed to a system for reducing thermal gradient at a heat engine. The heat engine includes a rotor assembly with a rotor disk and a seal assembly is provided. An interfacing structure at least partially surrounds the rotor assembly at the seal assembly. The seal assembly and the interfacing structure together form a first cavity defining a first environmental condition and a second cavity defining a second environmental condition. A fluid supply manifold is connected to the rotor assembly and is extended at least partially along a radial direction from the first cavity to an outlet opening in thermal communication with the rotor disk of the rotor assembly.

    Abstract: A heat management system for a turbomachine may include a first heat exchanger configured and arranged to receive a first fluid stream from a first duct, a second heat exchanger configured and arranged to receive the first fluid stream after discharging from the first heat exchanger, and a second duct fluidly communicating with the first duct between the first heat exchanger and the second heat exchanger to introduce a second fluid stream from the second duct to the first duct. A method of cooling fluid streams may include directing a first fluid stream from a first duct across or through a first heat exchanger, directing the first fluid stream across or through a second heat exchanger after discharging from the first heat exchanger, and directing a second fluid stream from a second duct to the first duct, with the second duct fluidly communicating with the first duct between the first heat exchanger and the second heat exchanger.

    Abstract: Provided are fluid exchange apparatuses and methods of exchanging fluids between streams. Exemplary fluid exchange apparatus includes a first interleaved pathway with a plurality of first passages, and a second interleaved pathway with a plurality of second passages, in which the plurality of first passages and the plurality of second passages interleave with one another. Exemplary methods include directing a first fluid through a first interleaved pathway of a fluid exchange apparatus and directing a second fluid through a second interleaved pathway of a fluid exchange apparatus. The first fluid may flow from an upstream portion of a first duct into the first interleaved pathway and may discharge into a downstream portion of the second duct. The second fluid may flow from an upstream portion of the second duct into the second interleaved pathway and may discharge into a downstream portion of the first duct.
