  • Non-Isotropic Fiber Reinforced Elastic Membranes for Micro Aerial Vehicle Wings

    Creator:
    Wilcox, Joshua Robert
    Abstract:
    Micro air vehicles (MAV's) and small unmanned aerial vehicles (SUAV) are remotely piloted or autonomous aircraft with a take-off mass range between 50 g and few kilograms. These vehicles, as well as natural fliers such as bats and insects, utilize a variety of elastic wing structures including thin membranes. Over...

  • Lift Enhancement of Pliant Wings Through Bio-Mimicry

    Creator:
    Osterberg, Nathaniel Brent
    Abstract:
    Flexible aerodynamic surfaces have been shown to favorably influence flight characteristics at low Reynolds numbers by increasing lift, angle of attack at stall, and resistance to perturbation. The objective of the research presented within this thesis is to investigate the influence of two aspects of flight observed in biological flyers,...

  • The energy extraction performance of an oscillating rigid and flexible foil

    Creator:
    Totpal, Alexander D.
    Abstract:
    The aerodynamic performance of an oscillating pitching and plunging foil operating in the energy harvesting mode is investigated. Experiments are conducted in a closed-loop recirculating wind tunnel at Reynolds numbers of 24,000 to 48,000, and reduced frequencies (k = fc/u) of 0.042 to 0.083. Foil kinematics are varied through the...

  • Predicting Aerodynamic Loads on Highly Flexible Membrane Wings

    Creator:
    Carpenter, Trenton James
    Abstract:
    Through passive adaptation to incidental flow, flexible aerodynamic surfaces exploit effects of increased lift, delayed stall and disturbance rejection. Wings of birds, bats, and insects exhibit these passive effects, and at the same time through the use of structural state feedback sensed from the loads on the wing, active control...
