  • GAS TURBINE ENGINE WITH SPLIT VARIABLE FAN EXIT GUIDE VANES AND AIRFLOW RADIAL TOTAL PRESSURE PROFILE RE-DISTRIBUTION
    Publication number: 20250376990
    Abstract: A gas turbine engine with split variable fan exit guide vanes including a fan duct supporting a circumferential pattern of split variable fan exit guide vanes, the split variable fan exit guide vanes comprising an upper section and a lower section, the upper section and the lower section each being adjustable about an axis extending along a span of each of the split variable fan exit guide vanes; an upper actuator in operative communication with the upper section, the upper actuator configured to independently adjust an incidence angle of the upper section responsive to predetermined gas turbine operating conditions; and a lower actuator in operative communication with the lower section, the lower actuator configured to independently adjust an incidence angle of the lower section responsive to the predetermined gas turbine operating conditions.
