Keywords: Buffet, unsteady aerodynamic pressure, Smart sensors and signal processing

Measurements of unsteady pressures with PVDF foils have been performed on two different models. The experiments are discussed using analysed time histories and power spectral densities of the stochastic unsteady pressure. The main aspect was the evaluation to technical industrial applicability of PVDF foils.
