The electron density distribution in an ionized gas flow 
induced by a high-frequency barrier discharge has been investigated 
by an optical method. It has been shown that ion acceleration occurs 
mainly near the minima of the electron density, and the extremes in 
the temperature distribution are in antiphase with the corresponding 
extremes of the electron density.

Keywords: aerodynamic drag, barrier discharge, shadow method.
