Abstract: A method for preventing fuel from migrating, i.e., infiltrating, into a mircoporous polymer membrane (16), such as that used in a fuel deoxygenator device (14) of an aircraft to remove dissolved oxygen from the fuel, includes heating the membrane (16) to reduce the size of micropores (32) in the membrane (16) from a first size (38) to a second size (46) that is large enough to allow migration of oxygen through the membrane (16) and small enough to prevent migration of fuel into the membrane (16). The membrane (16) is an amorphous fluoropolymer on a PVDF substrate and the micropores (32) are reduced in size by heating the membrane (16) at a temperature between 130 DEG C and 150 DEG C for 2 hours.

Abstract: A non-porous membrane suitable for use in removing dissolved oxygen in a fuel deoxygenator device in an aircraft is produced by solvent casting. A first membrane layer is deposited on a substrate. A second membrane layer is deposited on top of the first membrane layer. Subsequent membrane layers may be deposited on top of the second membrane layer as desired. The resulting non-porous membrane allows little or no leaking of fuel across the membrane.

Abstract: A cooling system for a gas turbine engine includes a fuel deoxygenator f or increasing the cooling capacity of the fuel. The fuel deoxygenator removes dissolved gases from the fuel to prevent the formation of insoluble deposits . The prevention of insoluble deposits increases the usable cooling capacity of th e fuel. The increased cooling capacity of the deoxygenated fuel provides a greater heat sink for cooling air used to protect engine components. The improved cooling capacity of the cooling air provides for increased engine operating temperatures that improves overall engine efficiency.

Abstract: A fuel system for an energy conversion device includes a deoxygenator system with a multitude of flow impingement elements which are interleaved t o provide a fuel channel with intricate two-dimensional flow characteristics. The flow impingement elements break up the boundary layers and enhance the transport of oxygen from the core of the of the fuel flow within the fuel channel to the oxygen permeable membrane surfaces by directing the fuel flow in a direction normal to the oxygen permeable membrane. The rapid mixing of the relatively rich oxygen co re of the fuel with the relatively oxygen-poor flow near the oxygen permeable membrane enhances the overall removal rate of oxygen from the fuel. Because this process can be accomplished in fuel channels of relatively larger flow areas while maintaining laminar flow, the pressure drop sustained is relatively low.

Abstract: A fuel system for a propulsion system includes a fuel deoxygenating device a nd a catalytic module containing catalytic materials. The fuel deoxygenating device removes dissolved oxygen from the fuel to prevent formation of insoluble materials that can potentially foul the catalyst and block desirable catalytic reactions th at increase the usable cooling capacity of an endothermic fuel.

Abstract: A system (10) for the management of thermal transfer in a gas turbine engine (14) includes a heat generating sub-system disposed in operable communication with the engine (14), a fuel source (18) configured to supply a fuel, a fuel stabilization unit (16) configured to receive the fuel from the fuel source (18) and to provide the fuel to the engine (14), and a heat exchanger disposed in thermal communication with the fuel to effect the transfer of heat from the heat generating sub-system to the fuel. A method of managing such thermal transfer includes removing oxygen from the fuel in the fuel atabilization unit (16), transferring heat from the heat generating sub-system to the fuel, and combusting the fuel in gas turbine engine (14). System (10) can be used for the thermal management of an aircraft.
