  • Flax as a Structural Reinforcement for Polymers

    Creator:
    McGeorge, Haley K.
    Abstract:
    Flax fibers are frequently used as a sustainable and recyclable reinforcement for composite materials in aesthetic applications (ex. car interiors). Flax fibers are biodegradable and can be sustainably harvested. Furthermore, the question of how to dispose of flax reinforced materials after the end of their lifetime can be solved in...

  • 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....

  • 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...

  • Light-Airplane Wing Structural Analysis and Material Selection

    Creator:
    Jablonski, John M.
    Abstract:
    The goal of this thesis is to explore the possibility of an upgrade of materials used in the wing-structure of a high-performance light aircraft operating under severe aerodynamic and inertial loads. The case aircraft considered in the thesis is the Caproni A-21 SJ, an all-metal high-performance motorglider powered by two...

  • Simulation of Steady Flight of Butterflies and Improvement of Parameter Optimization

    Creator:
    Selover-Stephan, Tassilo
    Abstract:
    Recent interest in nano aerial vehicles (NAVs) has sparked an increase in research on the mechanics of biological flapping flight. The ability of NAVs to fly in confined spaces and perform tight maneuvers make them a valuable technological asset. Researching the mechanisms behind small-scale flapping flight promises progress toward the...

  • Bird and bat interaction vision-based detection system for wind turbines

    Creator:
    Maurer, William Gage
    Abstract:
    Bird and bat collisions with wind turbine blades are an occurrence which are extremely variable in frequency. With the expansion of wind farms, determining the true quantity of collisions and the species involved is imperative for preventing ecological damage. Explored in this thesis is a blade mounted camera for wirelessly...

  • Wing Flutter Suppression via Distributed Electric Propulsion

    Creator:
    Bamberger, Joshua
    Abstract:
    This research aims to demonstrate the viability of actively controlled distributed-electric propulsion as a method to postpone flutter in high aspect-ratio elastic wings. A semi-wing on a spring mount with two propellers powered by electric motors, mounted at alternate pitch angles relative to the chord line, was used as the...

  • Calibration Methods for an Aerolab 375 Sting Balance to be used in Wind Tunnel Testing

    Creator:
    Van Hatten, Sean E.
    Abstract:
    Internal force, or sting, balances are used in wind tunnel testing to measure the total force and moment imposed on an aerodynamic structure. A sting balance operates through strain gauges converting strain from externally applied loads to voltage signals. An accurate measuring device is of paramount importance in wind tunnel...

  • Thermographic Testing Applied to Fiber Reinforced Polymers

    Creator:
    Jolibois, Michael
    Abstract:
    Non-destructive testing is a methodology to inspect production and operational parts for potential flaws, defects, or damages. The present work is based on pulsed wave thermography, a thermal imaging method based on heat conduction to identify surface and subsurface defects potentially present in a component. Pulsed wave thermography applies a...
