  • Gas turbine engine with axial flow fan with twin stream impeller and variable area bypass nozzle
    Patent number: 9926883
    Abstract: A gas turbine engine for a small aircraft such as a UAV having a bypass flow with a variable area bypass nozzle located at an outlet of the bypass channel, the nozzle having one position with a maximum flow area and a second position with a minimal flow area. The compressor is a twin stream compressor with an inner flow path for compressed air to the combustor and an outer flow path for the bypass channel. A fan stage can be used in front of the compressor.

  • COMBUSTION SYSTEM
    Publication number: 20160053680
    Abstract: A combustion system for gas turbine engine is disclosed. The combustion system includes a wave rotor drum and a drive coupled to the wave rotor drum. The wave rotor drum is mounted for rotation about an axis and is formed to include a plurality of combustion channels that extend along the axis to conduct transient waves along the axis during operation of the combustion system. The drive is coupled to the wave rotor drum and is adapted to drive rotation of the wave rotor drum about the axis.
