  • Design and Testing of a Tethered, Coaxial Rotor Micro Air Vehicle

    Creator:
    Shryer, Jacob R.
    Abstract:
    Unmanned Aerial System (UAS) technology is a rapidly developing technological marketspace. This thesis focuses on micro, tethered, coaxial UASs and the development of an electrically-tethered observation platform (ETOP). The thesis details the current status of the technology as well as current products on the market. Stability considerations, critical when adding...

  • Development of a remotely piloted aircraft for the Design/Build/Fly competition as a capstone engineering design project

    Creator:
    Wilcox, Joshua R.
    Abstract:
    The Design/Build/Fly competition (DBF) is an annual aerospace engineering competition hosted by the American Institute of Aeronautics and Astronautics (AIAA). Oregon State University's AIAA chapter competed for the first time at DBF in 2013 and finished in the top 25% which is a respectable finish for a first year team....

  • Machine Learning Applied to Non-periodic Event Detection – A Special Case in Structural Health Monitoring

    Creator:
    Hu, Congcong
    Abstract:
    Structural Health Monitoring (SHM) is known as the process of implementation of damage detection and characterization strategy. The method is widely used in modern critical equipment to minimize the risk of failures. While a significant effort has been devoted by researchers for the detection of faults in situations including periodic...

  • Theoretical modeling and experimental analysis of the flight mechanics of Lepidoptera

    Creator:
    Wilson, Tyler
    Abstract:
    Development of micro air vehicles has led to a strong interest in the biomechanics of flapping fliers such as bats, birds, and insects, due to their ability to perform extreme unsteady maneuvers and fly in confined spaces. Determining the methods and mechanisms used by these fliers is a valuable source...

  • Numerical and Experimental Investigation of Wing Flutter Suppression via Distributed Propulsion

    Creator:
    Anderson, Cole J.
    Abstract:
    In a seminal paper published in 1982, scientist have warned that humanity was pushing earth’s ecosystems beyond their capacities to support the web of life. One response to the concern was outlined by NASA with its vision for advanced fixed wing transport aircraft to be environmentally compatible and have revolutionary...

  • Fibers Microbuckling of Uncured Carbon-Epoxy Prepreg in Bending

    Creator:
    Guo, Yizhi
    Abstract:
    Prepreg is widely used in composite manufacturing with advanced composites such as carbon and aramid. The material is characterized by a degree of flexibility (drape) and stickiness (tack), which allows an efficient layup on molds with complex shapes. However, axial instability of compressed fibers during the molding process may occur,...

  • Dancer in the Wind Farm: Automated Eagle Monitoring and Deterrence

    Creator:
    Maurer, William G.
    Abstract:
    Improving the coexistence of eagles and wind energy is a critical effort for the sustainable expansion of the wind energy sector. Information about eagle activity and interactions with wind turbines enables verification of deterrence methods. This information can be broken into two categories: eagle activity in the airspace around wind...

  • 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...

  • Design and testing of an integrated wildlife-wind turbine interactions detection system

    Creator:
    Flowers, Jeremy Matthew
    Abstract:
    Bird and bat mortalities caused by interactions with wind turbines is a critical concern that requires addressing for conservation purposes. Deploying a low cost sensor array will be instrumental during site permitting, conducting impact assessments of existing wind farms, and assessing efficacy of wildlife mortality mitigation or wildlife deterrent technologies....

  • 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...
