Embedded Actuation and Sensing System (EASSy) for Gust Load Alleviation

Gust loads have a direct impact on the performance, wing structural weight and fatigue life of flight vehicles. Tao Systems proposes to develop an integrated embedded-actuation and sensing system (EASSy) to measure, monitor, and control spanwise aerodynamic loading of a flexible wing subjected to gust loads. EASSy will use surface hot-film signatures to measure the aerodynamic environment; active sensor circuit electronics will be used to measure and monitor structural response and accelerations; flight control will be accomplished with embedded actuators. The proposed approach will lead to a reduction in the wing structural weight, suppression of wing flutter, and the wing can be made mission-adaptable to achieve optimized aerodynamic efficiency for maximizing endurance or range of flight vehicles as well as their operational life.
