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 method of combusting an endothermic fuel with staged rich/lean combustion includes transferring thermal energy from a heat source, such as the wall of a rich combustor, to an endothermic fuel decomposition catalyst to cool the heat source and heat the fuel and catalyst to a temperature sufficient to endothermically decompose an endothermic fuel. The catalyst is contacted with the fuel to cause the fuel to decompose into a reaction product stream. The reaction product stream is mixed with a first air stream to form a first fuel/air mixture having an equivalence ratio greater than 1 and the first fuel/air mixture is combusted in a rich combustion stage to produce a combustion product stream. The combustion product stream is mixed with a second air stream to form a second fuel/air mixture having an equivalence ratio less than 1 and the second fuel/air mixture is combusted in a lean combustion stage to produce an exhaust gas stream containing decreased amounts of NOx. The invention also includes a system for practicing the method.

Abstract: A process for enhancing the thermal stability of hydrocarbon fuels used as coolants in vehicles operating at hypersonic speeds. The process includes introducing a strong reducing agent in a sufficient amount to chemically react with the dissolved oxygen present in the fuel, the introduction to preferably occur upstream of the fuel pump through a continuous pumping system and wherein the level of dissolved oxygen present in such hydrocarbon fuels is reduced to a level less than about 5 ppm.

Abstract: A fuel system for an energy conversion device includes a deoxygenator system (14) with a porous membrane. The deoxygenator includes an oxygen receiving channel (40) separated from the fuel channel (38) by the porous membrane (36). The capillary forces counteract the pressure differential across the membrane, preventing any leakage of the fuel, while the oxygen concentration differential across the membrane allows for deoxygenation of the fuel through the porous membrane.

Abstract: A fuel based thermal management system includes a fuel stabilization system which permits the fuel to exceed the traditional coking temperatures. High temperature components are arranged along the fuel flow path such that even at the highe r operating temperatures the fuel operates as a heat sink to transfer heat from high temperature components to the fuel. An optimal high temperature ester-based oil permits an oil-loop to exceed current oil temperature limits and achieve a high temperature to permit efficient rejection of heat to the fuel late in the fuel flow path.

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