Abstract
With the help of Figs. 3 and 4, subsection 2.1 of the full paper uses MEMS (microelectromechanical system) technology to explain the structural design of a micro balloon actuator; with the help of Figs. 6 and 7, subsection 2.2 explains the structural design and fabrication process of a piezoelectric micro synthetic jet actuator. Subsection 3.1 gives the test results of the performance of the actuator in subsection 2.1; subsection 3.2 gives those of the actuator in subsection 2.2. Section 4 presents in Figs. 12 and 13 the wind tunnel test results of the actuator in subsection 2.1; these results and their analysis show preliminarily that the micro balloon actuator can effectively control boundary layer separation, change the flow field of airfoil and achieve the goals of lift enhancement, drag reduction and auxiliary torque generation, etc.
