Integrated Flight Control and Flow Control Using Synthetic Jet Arrays

In this paper, a novel integrated flight control and flow control system using synthetic jet arrays is presented. In the proposed system, a novel active flow control actuator, synthetic- jets-instrumented-wingtips were designed to enhance or replace traditional roll control of a specified airplane. Wind tunnel experiments were conducted to obtain the dynamic model of the synthetic-jets-instrumented-wing-tips. A closed-loop active flow control system was developed to reattach the flow at high angle of attacks. A high fidelity dynamic model for the airplane with the designed synthetic-jets-instrumented-wing-tips was developed based on wind tunnel experiments. A nonlinear integrated flight control and flow control system was developed and tested in simulations. Simulation results showed that the synthetic-jets- instrumented-wing-tips, in conjunction with the elevator and rudder, can effectively control the Cessna's attitude.
