Dynamic Flight Maneuvering using virtual control surfaces generated by trapped vorticity Chao Song, Mark G. Allen The program focuses on achievement of rapid, dynamic maneuvering and attitude control for small scale UAVs. The required net forces and moments will be varied independently by dynamically tailoring the surface pressure distribution on lifting surfaces using a sparse array of hybrid fluidic actuators to manage the generation, accumulation and regulation of spanwise vorticity near the lifting surface and streamwise vorticity near the eing tips. This will be done with adaptive control architectures using closed-loop feedback from surface mounted pressure and flow direction (micro-tuft) sensors. Other universities that are a part of this MURI are the University of Texas at Austin, University of Illinois at Urbana Champaign and the California Institute of Technology, Pasadena.
