  • Supplemental cooling air for turbine exhaust components and surfaces
    Patent number: 11105265
    Abstract: A supplemental cooling air system for a turbine engine may comprise a compressor having an inlet and an outlet, and an electric motor operatively coupled to the compressor and configured to drive the compressor. The inlet may receive air from at least one of a freestream flow path, a bypass flow path, or an engine bay. The outlet may supply the air to at least a portion of the turbine engine for cooling.

  • SYSTEMS AND METHODS FOR MANUFACTURING FIBER-REINFORCED POLYMERIC COMPONENTS
    Publication number: 20180178432
    Abstract: Components may be manufactured by co-extruding a polymer filament and a fiber filament from a nozzle. The polymer filament and the fiber filament may be heated within the nozzle, which may couple the polymer filament to the fiber filament. The co-extruded filament may result in long reinforcing fibers which provide strength to the components.

  • Pulsed combustion fluidic nozzle
    Publication number: 20070144141
    Abstract: A propulsion system for producing thrust includes a turbine engine. The engine has a compressor, a combustor downstream of the compressor along a flow path, and a turbine downstream of the combustor along the flow path. A plurality of combustion conduits have outlets positioned to discharge combustion gas to form a fluidic nozzle throat.

  • Pulsed combustion engine
    Publication number: 20060096293
    Abstract: A pulsed combustion apparatus includes a conduit having an outer wall and an inner wall. The inner wall has a number of apertures. An interior space is separated from the outer wall by the inner wall. An induction system is positioned to cyclicly admit charges to the interior space. An ignition system is positioned to ignite the charges. Flow directing surfaces are positioned to at least cyclicly direct cooling air through the apertures.
