摘要
MEMS技术与流动控制技术的结合,使得流动主动控制技术的实际应用逐步成为现实,极大地推动了流动主动控制技术的发展。简述了流动主动控制技术的基本原理、关键技术,以及应用MEMS技术实现流动主动控制的机理和途径。介绍了几家国外研究机构近年来在流动主动控制技术领域基于MEMS技术的微传感、微控制和微执行技术及其集成技术的研究进展,以及在三角翼前沿涡控制、减阻研究、发动机喷流控制、细长体背风面分离流控制等方面的应用情况。
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.
