中文摘要：
边界层分离点检测是实现分离流主动控制的前提和基础，也是气动控制灵巧蒙皮系统研究的重点和难点。以流体边界层分离点检测技术为研究对象，以流体边界层分离点判定的风洞实验为验证目标，设计制作微型热敏传感器与聚酰亚胺柔性衬底，并首次利用微装配技术集成分立敏感元件与柔性衬底形成热敏传感器阵列。首先，采用分立元件通过表面贴装工艺来实现柔性微型热膜传感器阵列的集成，并研究该传感器阵列中敏感元件、柔性衬底的设计及传感器的排布。然后，在低速风洞实验中对传感器阵列的性能和传感器阵列输出信号采用统计量算法的方式进行处理判断，判定圆柱翼型的流体分离点位置。最后，对实验的结果所作的分析表明，该微型柔性热敏传感器阵列满足流体分离检测系统实时性、动态性的要求。
英文摘要：
Knowledge of wall shear stress is essential for understanding the dynamics of fluid flow, and its measurement holds great importance for investigating and controlling near wall turbulence and flow separation in aerodynamic control. Based on the well-established principle of thermal anemometry, an array of thin film sensors on a flexible polyimide substrate was designed and fabricated. Then, CFD （computational fluid dynamics） simulations were performed to estimate the corresponding shear stress distribution within the column cylinder aerofoil at flow velocity of 17.3 m/s. In wind tunnel tests, the result demonstrates that the above mentioned system can fulfill the dynamic and real-time characteristic requirements of the adaptive control system.
