  • Unconventional integrated propulsion systems and methods for blended wing body aircraft
    Patent number: 7665689
    Abstract: Integrated propulsion systems and methods for blended wing aircraft are disclosed. In one embodiment, a propulsion system at least one engine operatively disposed within an engine flow duct having an engine inlet and an engine exhaust aperture, and at least one fan operatively disposed within a fan flow duct having a fan inlet and a fan exhaust aperture. The engine and fan rotational axes extending at least approximately along a lengthwise direction of the aircraft, the fan flow duct being separate from the engine flow duct. A transmission assembly is operatively coupled between the at least one engine and the at least one fan, the transmission assembly being configured to transmit a rotary output from the at least one engine to rotate the at least one fan.

  • Reverse thrust inlet vortex inhibitor
    Patent number: 5915651
    Abstract: A method and apparatus are provided for inhibiting the formation of inlet vortices in a turbofan engine/nacelle installation 10 for use with an aircraft. The present invention redirects fan air from a fan air bypass duct 16, in a generally downward direction from the outer nacelle 18 in order to generate an air curtain 48 for inhibiting inlet vortex formation.
