A hybrid airfoil for a gas turbine engine is provided that includes a body and a panel. The body has a first side and a second side orientated opposite the first side. The first and second sides extend between a tip, a base, a leading edge and a trailing edge. The body includes a plurality of cavities disposed in the first side of the body, which cavities extend inwardly toward the second side. The cavities collectively form an opening. At least one rib is disposed between the cavities. A shelf is disposed around the opening. The panel is attached to the shelf first mounting surface and to the rib, and is sized to enclose the opening. The panel is a load bearing structure operable to transfer loads to the body and receive loads from the body.

A contaminant removal system is disclosed for selectively removing contaminants from a fluid stream. The contaminant removal system has a catalytic reactor of the type that is susceptible to deactivating agents, and is configured to remove contaminants from a fluid stream. The contaminant removal system has a first adsorbent device positioned upstream, with respect to the fluid stream direction, of the catalytic reactor, that is configured to chemically bind with and remove the deactivating agents from the fluid stream. The contaminant removal system can have a second adsorbent device positioned downstream, with respect to the fluid stream direction, of the catalytic reactor. The second adsorbent device is configured to remove undesirable byproducts that may be generated when the catalytic reactor removes contaminants from the fluid stream.

A method of making a passenger conveyor handrail includes forming a drive member having a plurality of longitudinally spaced drive surfaces. The drive member has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. The drive member is inserted into a molding device. A gripping surface portion of the handrail is formed using the molding device such that the gripping surface portion and the drive member are secured together. Another method includes forming a belt drive member having a plurality of teeth that establish a plurality of longitudinally spaced drive surfaces. The belt has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. Each of the teeth extends across an entire width of the belt. The belt is secured to a gripping surface portion of the handrail.

A hybrid fan blade for a gas turbine engine is provided that includes an airfoil and a composite panel. The airfoil has a first side and a second side orientated opposite the first side. The first and second sides extend between a tip, a base, a leading edge and a trailing edge. The airfoil includes a plurality of cavities disposed in the first side of the airfoil, which cavities extend inwardly toward the second side. The cavities collectively form an opening. At least one rib is disposed between the cavities. A shelf is disposed around the opening. The composite panel is attached to the shelf first mounting surface and to the rib, and is sized to enclose the opening. The first composite panel is a load bearing structure operable to transfer loads to the airfoil and receive loads from the airfoil.

A passenger conveyor handrail () includes a sliding layer () that is non-woven in some examples and non-fabric in other examples. A first polymer material is used to establish a body portion () of the handrail () to provide, for example, a gripping surface (). The sliding layer () is secured to a surface () of the handrail () to cover at least a portion of that surface to meet the needs of a particular situation. Disclosed examples include a variety of configurations and a variety of techniques for applying such a sliding layer () to a handrail ().

A passenger conveyor () includes a handrail assembly () comprising a handrail () having a plurality of co-extruded polymer materials (). In one example, an outermost portion () establishes a passenger gripping surface (). One example includes an extruded soft, low cost polymer in the middle of the handrail cross section to reduce cost and weight. A disclosed example includes a toothed driving surface () on an inner side made of a selected one of the polymer materials (). In one example, the driving surface () and the gripping surface () comprise the same polymer material.

Passenger conveyor handrail and method of manufacture

A passenger conveyor system () includes a handrail assembly () having a guidance () for guiding a moving handrail (). The example guidance includes an extrusion and presents a continuous, uninterrupted guiding surface () along which the handrail () travels. In a disclosed example, a single-piece extrusion () extends along an entire length of a balustrade (). A disclosed example includes a first material forming a body of the guidance () and a second material () establishing the guiding surface ().

A fuel stabilization system includes a first deoxygenator and a second deoxygenator both for removing dissolved oxygen from a hydrocarbon fuel. The first and second deoxygenators are arranged in parallel or series to sequentially remove a portion of dissolved oxygen from the hydrocarbon fuel. The arrangement of several deoxygenators for a single fuel stream improves removal of dissolved oxygen and provides for scalability of the fuel system to meet application specific demands. The arrangement also provides for the preservation of partial system functionality in the event of the failure of one of the deoxygenator modules.

A fuel system for an energy conversion device includes a deoxygenator system with a porous membrane. The deoxygenator includes an oxygen receiving channel 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.

Fuel deoxygenation system

A fuel system for an energy conversion device includes a deoxygenator system. A signal generator system includes a multiple of transducers located adjacent 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.

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.
