Abstract: In order to enhance the perturbation and improve the control effect of the plasma actuator, the plasma actuator, the characteristics of a novel magnetic acceleration plasma actuator were investigated by using high voltage probe, smoke line flow display technology and particle image velocimetry (PIV). The actuator discharge images at different time instants were obtained and the influence of magnetic field intensity on the electric characteristics and induced flow of the plasma actuator were analyzed. The results show that: (1) The directional motion speed of discharge plasma is proportional to the magnetic field strength, and the maximum motion speed of the magnetically accelerated plasma is up to 6 m/s; (2) The induced flow field of the magnetically accelerated plasma actuator has significant three-dimensional characteristics and unsteady characteristics and a series of induced vortices can be observed. The research results lay a foundation for the development of flow control technology based on the aerodynamic actuation of magnetically accelerated plasma.
