7. A vehicle, the vehicle comprising:
a propulsion system comprising a compressor section, a heat addition system comprising a combustor, and an expansion section in serial flow arrangement, wherein the heat addition system is configured to receive a flow of gaseous fuel to generate combustion gases;
a fluid circuit providing a flow of fluid, the fluid circuit being in fluid communication with the compressor section for receiving a flow of air from the compressor section, the flow of fluid comprising the air received by the fluid circuit;
a lubricant line providing a flow of lubricant to the propulsion system; and
a hydraulic fluid line providing a flow of hydraulic fluid to an actuator at the propulsion system,
wherein the fluid circuit provides the flow of fluid in thermal communication with the lubricant line and the hydraulic fluid line,
wherein a turbine is configured to receive the flow of air via the fluid circuit extended in fluid communication from the compressor section, wherein a flow control device is positioned along the fluid circuit upstream of the turbine and downstream of the compressor section, wherein the flow control device is configured to separate the flow of air into a first portion directed to the turbine and a second portion directed to a flow device, and wherein the flow device is configured to receive the first portion of the flow of air downstream of the turbine and the lubricant line, and wherein the flow device is configured to receive the second portion of the flow of air bypassing the turbine.
