N2 - The paper presents the results of experimental study of the ionic wind that emerges at a corona discharge in the needle-torus electrode system. In the experiment, we measured the current-voltage characteristic (CVC) and kinetic structure using the Particle Image Velocimetry (PIV) method for different polarities of the applied voltage in the range from the ignition of corona discharge up to pre-breakdown. We obtained velocity distributions along the symmetry axis and velocity profiles at different voltages. The electric wind at the negative polarity was found to emerge in the form of pulsed gas flows brought about by the current pulses (Trichel pulses). Snapshots of alternating charged gas clumps accelerating in interelectrode gap were taken.
