Abstract: A fuel delivery system for a gas turbine engine includes a main fuel pu mp supplying fuel to a fuel-metering device. The operational flow range of the fuel system is dependent on a minimum net positive suction pressure at the main pump inlet required to prevent pump cavitation. A mixture of fuel and dissolved gases increases the minimum net positive suction pressure required to prevent cavitation. A fuel de-aerator including a permeable membrane removes dissolved gases fr om the fuel to eliminate formation of dissolved gases. The elimination of dissolved gases from within the liquid fuel reduces the required net positive suction pressure, enabling a greater operational flow range.

Abstract: A fuel delivery system for an energy conversion device includes a fuel deoxygenator and an oxygen scavenger module for removing dissolved oxygen an d increasing the usable cooling capability of a fuel. Fuel emerging from the fuel-deoxygenating device flows into the oxygen-scavenging module where a second portion, smaller than the first portion of oxygen is removed from the fuel. The combination of the oxygen scavenger and the fuel deoxygenator provides an increase in removal of dissolved oxygen relative to the use of either device alone. The combination provides the desired increase in deoxygenation of fuel without the corresponding increase in device size.

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 communicatio n 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 dispos ed in thermal communication with the fuel to effect the transfer of heat from t he heat generating sub-system to the fuel. A method of managing such thermal transfer includes removing oxygen from the fuel in the fuel atabilization un it (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.
