| Research Abstract |
Bursting phenomenon of a laminar separation bubble formed over an airfoil is known to be a cause of airfoil stalls. The aim of this research is to suppress bubble burst and to avoid airfoil stalls. A burst control plate is a device that enhances vortical structures formed inside the laminar separation bubble and can suppress bubble burst. This plate was combined with a smart structure sensor actuator system to work as an autonomous airfoil stall suppression system. It was demonstrated that this autonomous system works effectively for stall angle delay.
