Aerodynamic research of actuator in flow control

Based on the technology of micro-electro-mechanical systems (MEMS), a balloon actuator was developed. The micro actuators arrays were put on a delta wing. CFD (computational fluid dynamics) simulations and wind tunnel experiments carried out about micro balloon actuator's influence on boundary layer separation eddy. The actuators can change the leading-edge vortices. And consequently, micro actuators on the proper position can provide sufficient rolling moments for flow control and change the dynamics quality of aircraft.
