Abstract: An analysis of the characteristics of a plasma actuator with a distributed tangential electric field has been performed. The generated thrust and energy efficiency were investigated experimentally and numerically for various waveform shapes of the applied voltage. Comparison with a classical configuration revealed increased thrust accompanied by a decrease in specific efficiency due to filament formation.

Keywords: surface dielectric barrier discharge, pulsed voltage, tangential electric field, electrohydrodynamics.
