| Abstract: | Active flow control is related to the flow mechanism and aircraft researches with real time and dynamic features. It becomes possible only after the applications of MEMS technology MEMS technology has opened a new territory for active flow control, and considerably accelerated the progress of active flow control technology. The fundamental principle, the key technologies and the mechanism that how and where MEMS could be used in active flow controls are discussed briefly in this paper. Advances of micro-sensor, microcontroller, micro-actuator, integration technologies, and their applications such as to leading edge separation vortices of delta wing, to drag reduction, to jet flow and to separation flow of slender bodies are reviewed. All of these show the merits of active flow control based MEMS, and the potential military and industry uses. |
