abstract

This paper presents an overview of research activities in MEMS/NEMS Lab of NWPU on applying MEMS to aerodynamic flow control domain. For the purpose of flow separation control, a kind of bubble actuator array was developed and fabricated. By mounted on the leading edge of the aerofoil, its feasibility for flow control has been demonstrated through wind-tunnel tests. In order to obtain flow state and determine the best actuation location for micro-actuator array, micro shear-stress sensor arrays have been investigated. An integration method of micro-sensors array was developed based on flexible PCB technology. Using this flexible substrate, micro-sensor arrays can be attached upon the surface of aircraft key position to realize distributed and realtime measurement of flow parameter.
