Research Interests
    Dr. Quackenbush has taken the lead on research efforts involving all aspects of modeling rotorcraft aerodynamics and dynamics, including extensive studies of rotor design optimization and unsteady airload computations for acoustics applications. A central focus of his most recent work has been applications of smart structures technology in rotorcraft, hydrodynamics, and propulsion venues, with and emphasis on Shape Memory Alloy devices; he has served as principal investigator or as a key contributor to five separate efforts in these areas over the past seven years. He has also recently headed modeling efforts at CDI that led to the development of both modeling methods and airfoil designs for low Reynolds number aerodynamics and has directed design studies of the aerodynamics and aeroacoustics of Unmanned Aerial Vehicles (UAVs).
