  • Lift and drag characteristics of flexible pitching and heaving wings

    Creator:
    Rushen, Jesse
    Abstract:
    There is a pressing need for Micro Air Vehicles (MAV) that are light, powerful, and efficient to perform military reconnaissance missions and search and rescue operations. These MAVs have length scales on the order of 10 cm, where traditional steady flight wing designs perform poorly. An alternative flight mechanism is...

  • 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...

  • Aircraft wing optimization using B-spline models and panel methods

    Creator:
    Jackson, Danielle Monique
    Abstract:
    This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...

  • 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,...

  • Modeling, control, and estimation of flexible, aerodynamic structures

    Creator:
    Ray, Cody W.
    Abstract:
    Engineers have long been inspired by nature's flyers. Such animals navigate complex environments gracefully and efficiently by using a variety of evolutionary adaptations for high-performance flight. Biologists have discovered a variety of sensory adaptations that provide flow state feedback and allow flying animals to feel their way through flight. A...

  • Multi Objective Aerodynamic Design in Formula SAE

    Creator:
    Arscott, Phillip J.
    Abstract:
    This thesis examines the effect of aerodynamics on Formula SAE cars. Due to the different objectives of the Formula SAE events, an understanding of the car's complete aerodynamic design is necessary. Using a half car computational fluid dynamics (CFD) model, a series of sensitivity studies are conducted to determine trends...

  • Simulation of drag reduction due to multi-aligned spheres

    Creator:
    Lindqvist, Varna
    Abstract:
    A method was sought to predict the flight paths and collisions for closely spaced ink droplets of various sizes as a design aid for ink-jet printing development. Computational fluid dynamics models of two rigid aligned spheres, as a proxy for ink droplets, were initiated in atmospheric pressure air at constant...

  • Aerodynamic undertray design for formula SAE

    Creator:
    Jensen, Karl
    Abstract:
    Aerodynamic improvements in automotive racing can have a significant effect on vehicle performance. Recent developments in Formula SAE (Society of Automotive Engineers) have included the design and implementation of aerodynamic devices such as inverted wings and undertrays to improve performance. In this work the literature of undertray technology is presented...
