Cyber-Physical Systems to Understand the Dynamics of Nonlinear Aeroelastic Systems for Flexible MAVs and Energy Harvesting Applications
Abstract
We report on the approach taken and progress made during the three year research program. The goals of the program were to develop parallel experimental and theoretical approaches to study the dynamics of high-amplitude aeroelastic instabilities dominated by unsteady vortex shedding. Current approaches, both experimental and theoretical fall short in their abilities to simulate a wide range of operating conditions and to simulate them in a reasonable timeframe. We demonstrate the successful development of a cyper-physical experimental system, capable of close-to arbitrary definition of the structural characteristics of an aerodynamic structure (stiffness, damping and mass) and demonstrate a complex stability landscape and a complex, but universal vortex formation scaling. We also demonstrate how an asymptotic method based on classical boundary layer theory can be used to develop a feasible numerical model for the rapid simulation of these complex systems.
