Abstract
An aircraft propulsion system in includes a compressor section, a heat addition system, and an expansion section in serial flow arrangement, wherein the heat addition system is configured to receive a flow of gaseous fuel from a fuel system, and wherein the flow of gaseous fuel is provided to the heat addition system to generate combustion gases. A lubricant system is configured to provide a flow of lubricant through the propulsion system. A hydraulic system is configured to provide a flow of hydraulic fluid to an actuator at the propulsion system. A thermal management system is configured to provide a flow of fluid in thermal communication with the lubricant system and the hydraulic system. The thermal management system comprises a turbine configured to receive the flow of fluid via a fluid circuit extended in fluid communication from the compressor section.
