  • External turning vane for IFS-mounted secondary flow systems
    Patent number: 11022047
    Abstract: An external turning vane includes a vane body extending radially from the inner cowl and disposed upstream from an inlet of the secondary flow system, the vane body configured to turn an airflow in a bypass flow path towards an axial direction to minimize separation between the airflow and the secondary flow system.
    Type: Grant

  • Fence for duct tone mitigation
    Patent number: 10487744
    Abstract: Aspects of the disclosure are directed to a system associated with an engine of an aircraft comprising: a duct, an inlet coupled to the duct, and a fence coupled to the inlet or located upstream of the inlet. In some embodiments, the system further comprises a valve body coupled to the duct. In some embodiments, the valve body includes at least one valve that is configured to rotate between a closed state and an open state.

  • Aerodynamic track fairing for a gas turbine engine fan nacelle
    Patent number: 10240561
    Abstract: A gas turbine engine includes an aerodynamic track fairing adjacent to a convergent-divergent nozzle, the aerodynamic track fairing including a localized curvature along an outside edge. The aerodynamic track fairing is configured to offset a circumferential pressure gradient otherwise introduced in part by a transition between the convergent-divergent nozzle with the aerodynamic track fairing.
