Development of Airfoil Stall Suppression System Utilizing Smart Structure Sensor Actuators

一个层流分离气泡在机翼上形成的爆裂现象被认为是机翼失速的原因。本研究的目的是抑制气泡破裂和避免翼型失速。破裂控制板是一种增强层流分离泡内形成的螺旋结构，抑制泡破裂的装置。该板与智能结构传感器致动器系统相结合，作为一个自主翼型失速抑制系统。仿真结果表明，该自主控制系统能够有效地解决失速角延迟问题。

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.
