  • Investigation and Implementation of a Liquid Feeding System for the Apis mellifera Honey bee under Laboratory Conditions

    Creator:
    Meador, Brett W.
    Abstract:
    Studying honey bee behavior is a very important aspect of horticulture, especially in recent years as honey bee colonies face population decline, or colony collapse. While studying honey bees, researchers often keep honey bees in captivity, where it can be challenging to meet nutritional and hydration requirements using existing liquid...

  • Effects of nickel addition In Cu-Zr-Hf-Al metallic glass matrix

    Creator:
    Miska, John
    Abstract:
    Metallic glasses (also referred to as amorphous metals) have been gaining interest in the materials science community in recent years. These amorphous materials demonstrate promising properties compared to their crystalline counterparts that include much higher strength and elastic strain limit, better corrosion and wear resistance, superior soft magnetism, and an...

  • 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...

  • Female Mold Fabrication Process Development with Pre-Impregnated Composite Materials for Application to Sub-Orbital Rockets

    Creator:
    Hayden, Muriel A.
    Abstract:
    The leading edge of a sub-orbital, sounding rocket dictates an aerodynamically optimal profile which is difficult to manufacture. The university level offers no current standard to produce rocket nose cones made with pre-impregnated composites. Of particular interest is the molding technique used to fabricate a nose cone. The focus of...

  • 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...

  • Testing and design procedures for electric propellant pumps for suborbital bi-propellant rockets

    Creator:
    Verna-Ketel, Dominic
    Abstract:
    An electrically driven propellant pump (HALE E-Pump) was analysed and tested to determine its viability for use in a bi-propellant launch vehicle for the High-Altitude Liquid Engine (HALE) student rocket team at Oregon State University (OSU). The pump, manufactured in 2022 by students in OSU machine shops, was hydrostatically tested...

  • Ergonomic Analysis of the Global Formula Racing Driver Interface

    Creator:
    Davis, Sean M.
    Abstract:
    Between Oregon State University and DHBW Ravensberg, Global Formula Racing produces two Formula style vehicles every year for competition. This thesis has served as a pre-development project in the ergonomics and driver interface of the team's vehicles. This project will determine the position of the seat back, steering wheel, and...

  • Thin Film Bi-based Perovskites for High Energy Density Capacitor Applications

    Creator:
    Shear, Colin David
    Abstract:
    Pulsed laser deposition was used to create 0.1-Bi(Zn₀.₅ Ti₀.₅)O₃-0.9-BaTiO₃ (BZT-BT) thin films to examine the effects of laser energy (2.25 or 2.5 J/cm²) , pulse frequency (2 Hz or 5 Hz), and deposition temperature (550, 600, 650, and 700°C) on the electrical properties of the films. These effects were analyzed...

  • Unmanned Aerial Vehicle Propulsion

    Creator:
    Brown, Sean
    Abstract:
    There is a growing US interest in UAVs for many applications ranging from agriculture to military. One area of improvement that can be realized in each category is propulsion. Engines with greater efficiency would result in longer mission duration, leading to cost savings and increased usefulness for UAV owners and...
