Abstract: A new approach to producing powerful electrohydrodynamic flows in a gas environment is discussed, in which a barrier discharge distributed over a dielectric surface is used as an intense ion source. Electric discharge systems for active control of gas flows with a high (>15 l $\rm s^{-1}$) volumetric rate are developed and investigated. A highly effective multidischarge actuator system is created to control air flows over aerodynamic surfaces with a significantly higher actuator force and energy characteristics than those in known global analogs.

Keywords: electrohydrodynamic flow, ion beam, barrier discharge, multidischarge actuator.
