This paper presents a part of the works conducted in the Plasmaero European project (task 1.1) on surface dielectric barrier discharge actuators applied to airflow control. The study is divided into several parts. In the first part, the goal is to enhance the electric wind produced by a typical single DBD actuator by optimization of the active electrode shape. For instance, the use of a thin wire instead of a plate air-exposed electrode has shown that the body force can be increased from 65 to 97 mN/m for a power consumption of 1 W/cm. Secondly, plasma vortex generators are presented. The interaction between the spanwise-directed body force and the oncoming boundary layer is illustrated. In the third part, the interest of using threeelectrode based sliding discharges for largescale applications is highlighted. The final part deals with multi-DBD actuators that result in an increase of the electric wind velocity up to 10.5 m/s. This has been previous limited to about 7 m/s until now.
