Abstract
A nozzle wall for an air-breathing engine, the nozzle wall including a first wall surface subject to engine exhaust flow, a nozzle cooling system including at least one heat exchange fluid passage disposed adjacent the first wall surface so as to increase a temperature of a cooling fluid flowing from a fluid reservoir to at least a power extraction device, and the cooling fluid is ejected from the nozzle cooling system downstream from the power extraction device.
Claims20
A nozzle wall for an air-breathing engine, the nozzle wall comprising:
- a first wall surface subject to engine exhaust flow;
- a nozzle cooling system including at least one heat exchange fluid passage disposed adjacent the first wall surface so as to increase a temperature of a cooling fluid flowing from a fluid reservoir to at least a power extraction device;
- and
- wherein the cooling fluid is ejected from the nozzle cooling system downstream from the power extraction device.
A vehicle comprising:
- an air-breathing engine having a nozzle where engine exhaust flow exits the air-breathing engine through the nozzle;
- a nozzle cooling system including a first cooling subsystem coupled to the nozzle so as to transfer heat from the nozzle to a cooling fluid flowing from a fluid reservoir to at least a power extraction device;
- and
- wherein the cooling fluid is ejected from the nozzle cooling system downstream from the power extraction device.
A method for operating a vehicle, the method comprising:
- transferring heat to a cooling fluid from a nozzle of an air-breathing engine of the vehicle using a first cooling subsystem of a nozzle cooling system coupled to the nozzle, where the cooling fluid flows from a fluid reservoir through the first cooling subsystem to at least a power extraction device, and where engine exhaust flow exits the air-breathing engine through the nozzle;
- and
- ejecting the cooling fluid from the nozzle cooling system downstream from the power extraction device.
