Characteristic features of a barrier discharge occurring on the zhukovskii aerofoil on variation of the surrounding air pressure

Abstract

The results of measuring the jet thrust produced by a dielectric barrier discharge on the Zhukovskii aerofoil are presented. The measurements were made in the pressure range 40–1200 Torr. The maximum velocity of the ion wind attained 4–5 m/s. Based on the analysis of the plasma glow spectrum at a residual air pressure in the vacuum chamber of 40 Torr in the barrier discharge, the values of the temperature Te ~ 2.5⋅104 K and of electron concentration Ne ~ 2⋅1015 cm-3 were obtained.
