Dynamic Flight Maneuvering Using Virtual Control Surfaces Generated by Trapped Vorticity

摘要

This MURI program addressed integrated closed-loop control of flow and dynamic maneuvering for small UAVs without moving control surfaces. Forces and moments were varied using synthetic jet actuators to effect vorticity generation/accumulation near lifting surfaces, with sensing provided by surface-mounted pressure and flow-direction sensors, and a reduced-order model (ROM) of vorticity dynamics coupled to and integrated with a vehicle dynamics model in an adaptive control architecture.
