Active control technology in the unsteady aerodynamics of fast moving surfaces, and systems identification technology are reviewed. Computation programs were developed for the prediction of the unsteady flow about airfoils and wings, with fast control surface movements. Wind tunnel tests with a supercritical airfoil model and two very large halfwing models with fast moving control surfaces, including spoilers, provide the data base for extrapolation to full scale conditions.
