title = "Suction flow control at high reynolds number",
abstract = "Flow control has been shown to reduce the aero-optic distortion due to density fluctuations within a wake of an airborne turret. By manipulating the flow over the turret directly affects the density fluctuation that incur aero-optic distortions. This paper focuses on suction flow control over a three-dimensional turret at a freestream velocity of Mach 0.3. Aero-optic measurement were taken over the flat aperture of the turret with and without open loop suction control clearly showed a decrease in the distortions as the amount of suction increased. Fluctuating surface pressure simultaneously sampled with the aero-optic measurements showed the inverse where as the suction increased the surface pressure rms decreased. Another set of tests were taken as the hemisphere dynamically pitching with open-loop and closed-loop suction flow control. The closed-loop control system employed a low dimensional measurement based proportional controller. Both the open-loop and closed loop control test showed a change in flow over the aperture as compared to the baseline case.",
