Using Cyber-Physical Systems to Study the Dynamics of Unsteady Leading Edge Vortices with Cross-Stream Flows
Abstract
The focus of the research was to characterize the LEV dynamics and aeroelastic instabilities associated with swept wings - wings in which there is a significant cross flow velocity. The effort was a combined experimental (at both Brown and USAFA) and computational (at the USAFA). The experiments at Brown were conducted in the 0.6 x 0.8 meter water tunnel, while experiments at USAFA were conducted in the 3 foot by 3 foot wind tunnel. Key accomplishments include the development and refinement of cyber-physical experimental aparatus at Brown and USAFA, characterization of stability maps and energy maps for both unswept and swept wings, and the measurement and computation of key flow structures associated with high amplitude pitching wings.
