Abstract:
An assembly is provided for a turbine engine. The assembly includes a fuel injector and a fuel vaporizer. A nozzle of the fuel injector is adapted to direct fuel to impinge against the fuel vaporizer. The fuel vaporizer is adapted to substantially vaporize the impinging fuel.
Abstract:
One embodiment includes a fuel injector. The fuel injector assembly comprises a conduit for conveying fuel from a fuel inlet to a nozzle. The conduit is located in a support, with the conduit, the nozzle, and the support being a single unitary piece. A thermally compliant feature is located at the nozzle which allows the fuel injector to adjust for differential thermal expansion.
Abstract:
A method of forming an object includes installing multiple foil drums within a processing chamber of an ultrasonic consolidation system. The multiple foil drums each include different materials than the other foil drums. The multiple foil drums are positioned so that one of the foils is selected to be placed on top of the build platform. The selected foil is welded onto the build platform or onto a previously processed layer. A portion of the welded foil is then cut. The multiple foil drums are retracted away from the build platform. The portion of the welded foil that was just cut is then consolidated to the object. The build platform is incrementally lowered before the process is repeated to form the next layer of the object.
Abstract:
A method includes designing a part. The part includes at least one internal structure. The internal structure is designed to provide strain mitigation, energy dissipation, or impact resistance for the part during an emergency condition. The part is built by a layer-by-layer additive manufacturing process. While building the part, the internal structure is connected to the part.
Abstract:
A method includes building a tubular object by a layer-by-layer additive manufacturing process. A structure integrally connected to the tubular object for supporting a portion of the tubular object is formed during building of the tubular object. The structure provides vibration dampening, heat shielding, heat transfer, stiffening, energy absorption, or mounting after the tubular object is built.
Abstract:
A system for dispersing a catalyst in a fuel includes a first reservoir (12) containing the fuel, and a second reservoir (24) including an agitator (26) and containing a quantity of the catalyst suspended in the fuel. The system also includes a first conduit (14) extending from the first reservoir, a second conduit (28) extending from the second reservoir, and a mixing nozzle (16) connected to the first conduit and the second conduit. The mixing nozzle (16) includes a first meter (34) positioned within the first conduit, a second meter (32) positioned within the second conduit, a valve (30) positioned upstream from the second meter within the second conduit, a junction (36) in flow communication with the first conduit and the second conduit, a mixer (38) downstream from the junction, a sensor (40) positioned between the mixer and an outlet; and a controller (42) connected to the valve and the first and second meters, the controller receiving feedback from the sensor.

Abstract:
A heat exchanger article (22) includes a hollow tube (24) that has a tube wall (26) with an interior surface (26a) and an exterior surface (26b). The interior surface (26a) defines a flow passage (28) through the hollow tube (24). The hollow tube (24) also includes a vane cluster (30) in the flow passage (28). The vane cluster (30) includes a plurality of vanes (32) and each of the vanes (32) extends inwardly from the tube wall (26).
