The possibilities of piezoelectric sensor arrays for the investigation and analysis of laminar-turbulent flow at airfoil profiles, with a view to the characterization of the flow conditions as well as to the detection of flow instabilities in the transition region are discussed. Both wind tunnel tests and free flight tests demonstrated that piezoelectric foil arrays are a valuable and practicable aid in current laminar airfoil research.
