摘要： A gas turbine engine includes a variable area nozzle having a plurality of flaps. The flaps are actuated by a plurality of actuating mechanisms driven by shape memory alloy (SMA) actuators to vary fan exist nozzle area. The SMA actuator has a deformed shape in its martensitic state and a parent shape in its austenitic state. The SMA actuator is heated to transform from martensitic state to austenitic state generating a force output to actuate the flaps. The variable area nozzle also includes a plurality of return mechanisms deforming the SMA actuator when the SMA actuator is in its martensitic state.

摘要： A fuel system for a gas turbine engine removes oxygen from fuel with a fuel stabilization unit (FSU). The FSU includes a first vacuum stage, where vacuum pressure is created by an ejector and a second vacuum stage where vacuum pressure is created by the ejector and a vacuum pump. The vacuum stream from the first vacuum stage and the second vacuum stage flow through the ejector. The vacuum stream from the second vacuum stage is all that passes through the vacuum pump.

摘要： A system for the management of thermal transfer in a gas turbine engine includes a heat generating sub-system in operable communication with the engine, a fuel source to supply a fuel, a fuel stabilization unit to receive the fuel from the fuel source and to provide the fuel to the engine, and a heat exchanger in thermal communication with the fuel to transfer heat from the heat generating sub-system to the fuel. A method of managing thermal transfer in an aircraft includes removing oxygen from a stream of a fuel fed to an engine used to drive the aircraft, transferring heat from a heat generating sub-system of the aircraft to the fuel, and combusting the fuel. A system for the thermal management of an aircraft provides for powering the aircraft, supplying a fuel deoxygenating the fuel, and transferring heat between a heat generating sub-system of the aircraft and the fuel.

摘要： A streamlined body has oppositely facing external pressure and suction surfaces that meet to form a leading edge region. Passageways within the body direct pressurized fluid from passageway outlets over the pressure surface toward the leading edge region at a shallow angle with respect to the pressure surface. The pressurized fluid travels around the leading edge region to the suction surface, energizing the boundary layer on the suction surface.

摘要： A fuel deoxygenation system includes an oxygen permeable membrane having a porous membrane and an oleophobic layer. The porous membrane has pores that create a passage extending from a first side to an opposite second side of the porous membrane. The pores have an average pore diameter less than or equal to about 0.06 microns. The oleophobic layer and the porous membrane allow oxygen to cross the oxygen permeable membrane but substantially prevent fuel from crossing the oxygen permeable membrane. A method for removing dissolved oxygen from a fuel includes delivering fuel to an oxygen permeable membrane and removing oxygen from the fuel using the oxygen permeable membrane. A method for modifying a surface of a porous membrane includes depositing an oleophobic treatment agent on the porous membrane, removing solvent and heating the porous membrane to form an oleophobic layer on the porous membrane.
