Abstract
A turbulence generation system includes a vane assembly to direct airflow from a nozzle. The vane assembly includes at least two vertically oriented nozzle contraction vanes, a pair of vertically oriented nozzle exit vanes, and at least one horizontally oriented vane. The nozzle contraction vanes are located within the nozzle upstream of a nozzle air outlet. Each nozzle contraction vane rotationally moves independent of the other nozzle contraction vane to generate airflow pressure loss, turbulence and/or flow vectoring. The nozzle exit vanes are downstream of the air outlet and rotationally move to generate higher angles of dynamic yaw or a quick yaw input. The nozzle exit vanes are positioned laterally inward from first and second sidewalls of the nozzle. The horizontally oriented vane is positioned downstream of nozzle contraction vanes and upstream of the nozzle exit vanes and rotationally moves to generate up-wash or downwash.
