  • 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.
    Type: Grant

  • Pulsed combustion engine
    Patent number: 7752835
    Abstract: A turbine engine has a case with an axis. A fan is mounted for rotation about the axis. A turbine is mechanically coupled to the fan to drive rotation of the fan about the axis. A number of compressor/turbine units are downstream of the fan and upstream of the turbine along a core flowpath. A number of compressors are coupled to the compressor/turbine units to receive air and deliver combustion gas to drive the turbine.

  • Pulsed combustion engine
    Patent number: 7100360
    Abstract: A pulsed combustion device includes a support structure and a combustor carousel supported by the support structure and rotating relative thereto about an axis. The carousel has a number of combustion conduits in a circumferential array. Each conduit cyclically receives a charge and discharges combustion products of the charge.

  • Aircraft nacelle ventilation and engine exhaust nozzle cooling
    Patent number: 5586431
    Abstract: This disclosure relates to a system for purging of the nacelle of an aircraft and for cooling the edge pieces of the divergent flap of a gas turbine engine's two-dimensional exhaust system by use of long tubular air pump with axisymmetric supersonic nozzles, a rectangular mixing chamber for pumping nacelle air with fan discharge air and judiciously flowing the air in separate passageways formed in the double clamshell convergent flap of the exhaust nozzle. This reduces the overall aircraft and weapon system weight, with only a minimum increase in the engine's nozzle weight.
