A program to develop flow control techniques to reduce aero-optic distortion due to near field turbulence is proposed. The program combines the use of advanced computational techniques such as Large Eddy Simulations, new experimental methods such as Particle Image Velocimetry (PIV) and Laser Speckle techniques, along with actuator development and modeling technology to achieve this goal. The demonstration of the technology will be carried out at laboratory scale for two different configurations of interest to the USAF. However, the flow control techniques developed take into consideration issues of Adaptive Optics (AO) system performance limitations and component latencies so that the developed techniques are integrable in full scale systems. The proposed program will explore passive and active (open and closed loop) control methods and quantify the gains from each control technique.
