Abstract: PROBLEM TO BE SOLVED: To provide a fuel stabilization system capable of removing dissolved oxygen from fuel to raise fuel temperature and being adapted to different demand conditions for removing oxygen. SOLUTION: This fuel stabilization system 10 is provided with a fuel tank 12 for supplying fuel to an engine 15 by a fuel pump 14. Dissolved oxygen is removed from fuel by a fuel stabilization assembly 16 provided with a plurality of oxygen removers 18, 20, 22, 24, 26 arranged in parallel. A part 30 of dissolved oxygen is removed from fuel by each fuel oxygen remover and is exhausted to the outside. Temperature of flowing-in fuel is within a scope of limit temperatures for preventing promotion of generation of insoluble substance under the presence of dissolved oxygen. Since fuel flowing out of the fuel stabilization assembly 16 contains less amount of dissolved oxygen, it is possible to heat fuel up to higher temperatures. Fuel is moved and heated by a heat transfer device 32. Efficiency of the engine is improved by improved temperature characteristic of fuel. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To efficiently and cost effectively plate the front ends of aerofoils coated at their blade parts with an insulating material exclusive of their front ends by placing the aerofoils into fixtures and applying a sealant to the aerofoils and the fixtures, then electroplating both. SOLUTION: The blade parts 14 of the aerofoils 10 having route parts 12 and the blades 14 are coated with the insulating material and further, the insulating material is removed from the front ends 16 of the blade parts 14 to expose the front ends 16 to be electroplated. The insulating material is preferably a UV curing the material and is preferably removed from the front ends 16 after the material is cured. The aerofoils 10 exposed with the front ends 16 are placed on the fixtures 20 and are connected via the route parts 12 to electric contacts 32. The fixture assembly is then immersed into a sealing bath and is hermetically sealed and enveloped with a thermoplastic hot-melt coating, etc., while the front ends 16 are held exposed. The fixture assembly is then immersed into an electroplating bath and the electroplating of the front ends 16 is executed.

Abstract: A fuel system for an energy conversion device includes a deoxygenator syst em with a porous membrane. The deoxygenator includes an oxygen receiving channe l separated from the fuel channel by the porous membrane. 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 process for electroplating a portion of an airfoil comprises the following steps; providing an airfoil having a root portion and a blade portion, the blade portion having a tip remote from the root portion; coating at least part of the blade portion including the tip with an insulating material to produce a partially insulated coated airfoil; removing the insulating material from the tip of the blade portion to be electroplated; mounting the airfoil with exposed tip in a fixture wherein the airfoil contacts an electrical contact; immersing the fixture with airfoil in a sealing bath so as to sealingly encase the fixture and at least a portion of the insulated coated airfoil while leaving the tip exposed to form a fixture assembly with a partial sealant coating; immersing the fixture assembly in an electroplating bath for electroplating the tip of the airfoil; and removing the fixture assembly from the bath. Therefore is used an apparatus for selectively electroplating the tip portion of an airfoil.

Abstract: A fuel system for an energy conversion device includes a deoxygenator syste m. A signal generator system includes a multiple of transducers located adjacen t a fuel channel. The transducers are arranged to generate acoustic flow chaotization and cavitation-induced phase separation which destroys oxygen depleted boundary layers and significantly improving flow mixing, intensifying oxygen supply to the surface of an oxygen-removing membrane of the deoxygenator system.

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 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.

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.
