Description
Derived from Wei Shyy personal interest in bird watching as well as its relevance to interdisciplinary research in flying sensors, fascinating features of biological flight will be presented. In particular, aerodynamics associated with moving wings pose many interesting questions while offering substantial opportunities beyond our current engineering practices. Many emerging and novel concepts related to power generation, locomotion in air and water, sensing and actuation interact substantially with moving wings. In this talk, we focus on moving wings which operate under low Reynolds number, exhibit structural flexibility, need to deal with uncertain environment and disturbances of magnitudes comparable to baseline conditions, and adapt based on limited information, often via passive control. These small systems also enjoy certain favorable scaling characteristics including structural strength, reduced stall speed, and impact tolerance. We will discuss our recent efforts in understanding the aerodynamics and aero elasticity related to small moving wings including scaling laws, multi-wing interactions, and aspects deviating from those of fixed, rigid wings.
