dc.description.abstractA three year effort to study the "Compressibility Effects on the Control of Dynamic Stall of Oscillating Airfoils" was funded by ARO in 1990. A fourth year extension was granted for the project. As part of this research, a new real-time interferometry system known as Point Diffraction Interometry (PDI) was developed. Several new and exciting details of the dynamic stall flow over an oscillating airfoil such as formation of multiple shocks were captured. The study also addressed the role of transition in influencing the dynamic stall process. A concurrent computational study was carried out to investigate the role of transition. Additionally, LDV measurements of the dynamic stall flow were obtained which support the PDI observations. A high speed PDI "movie" imaging system was designed to capture events of dynamic stall during a single pitch-up motion of the airfoil. This report describes the significant results obtained from the four year study of dynamic stall over an oscillating airfoil.en_US
