一种微气泡型MEMS作动器研究

Research of a MEMS Balloon Actuator

设计了一种基于MEMS技术的微气泡型作动器,将微作动器布置在NACA0012翼型和三角翼机的前缘上,利用Fluent进行数值模拟,结果表明微作动器可以改变机翼前缘附体流的流动状态,提高翼型升力系数,改变三角翼机前缘流动状态,利用微作动器可以成功进行流动控制。

A MEMS balloon actuator is designed and fabricated. We dispose micro actuators on NACA0012 wing and delta wing. Micro actuator has great effect to aerofoil by Fluent numerical simulation . The simulations also carry out about micro balloon actuator's influence on boundary layer separation eddy, and the influence to rolling moment under different position of micro actuator. Micro balloon actuators can generate an additional moment for controlling dynamics aircraft.
