Abstract: A system for directing airflow, a gas turbine engine, and a method for directing airflow exiting a cascade of internal airfoils are provided. An exemplary system for directing airflow includes a cascade of internal structures spanning an airflow path. Each of the internal structures includes a rounded trailing edge. The system further includes at least one plasma generating device positioned on the rounded trailing edge of each internal structure. Also, the system includes a controller configured to selectively energize and de-energize each plasma generating device to selectively alter a direction of local airflow around each internal structure to produce a combined airflow exiting the cascade in a desired direction.

Abstract: A system for directing airflow, a gas turbine engine, and a method for directing airflow exiting a cascade of internal airfoils are provided. An exemplary method for directing airflow exiting a cascade of internal airfoils includes coupling a first plasma generating device on a first surface and a rounded trailing edge of each of the internal airfoils. The method also includes coupling a second plasma generating device on an opposite second surface and the rounded trailing edge of each of the internal airfoils. Further, the method includes selectively energizing the first plasma generating device and the second plasma generating device on each of the internal airfoils to produce a plasma and to selectively alter a direction of local airflow around each of the internal airfoils to produce a combined airflow exiting the cascade in a desired direction.
