    • Automated Dynamic Propeller Testing At Low Reynolds Numbers 

      Gamble, Dustin Eli (Oklahoma State University, 2009-12-01)
      Experiments were conducted on small propellers using a motor dynamometer in a wind tunnel. The effects at different Reynolds number were observed. To maintain Reynolds number and consistent test procedures, the wind tunnel ...

    • Design of a Hybrid Rocket / Inflatable Wing Uav 

      Sudduth, Cory W. (Oklahoma State University, 2012-12-01)
      This paper discusses the design challenges and development of a UAV that transitions from a rocket, which allows the aircraft to reach a target altitude rapidly, and then deploys an inflatable wing from an enclosed shell ...

    • Development of a dolphin hormone sample collection device for UAS 

      Abele, Eric (2021-07)
      Marine biologists are able to quantify the stress in dolphins through analysis of hormones in mucus samples released from the blowhole while breathing. This method provides a noninvasive approach compared to current methods ...

    • Development of optimized path planning and autonomous control for return-to-point vehicle of high altitude ballooning 

      Lee, Seong-Jin (2014-07)
      In 2004, The Atmospheric and Space Threshold Research Oklahoma (ASTRO) program was launched to provide access to the near space environment for both educational and research purposes. Mainly, this ASTRO vehicle consisted ...

    • Portable Recovery System for an Unmanned Aircraft with a Straight Wing and a Tractor Propeller 

      Delano, Brian A. (2019-07)
      The recovery system development effort for an unmanned aircraft (UA) has been documented and examined. The development effort existed to satisfy a customer's need to recover an 80 lb aircraft on unimproved terrain. The ...

    • UAV Power Plant Performance Evaluation 

      Ravi, Ashwin (Oklahoma State University, 2010-05-01)
      UAV's are proven to be cost effective when compared to manned aircraft and minimize the risk related to a pilot's life. The primary focus of my research was on identifying and evaluating state of the art propulsion ...

    • Use of armed drones by law enforcement: A need for essential elements in policy 

      Jones, Gary L. (2019-12)
      In 1936, Lt. Cmdr. Fahrney, Officer in Charge of the Navy's Radio-Controlled Aircraft Project, introduced the term drone in his semi-annual report for aerial targets. Later, in 1946, the United States military used the ...

    • Winglet Design and Optimization for Uavs 

      Weierman, Jacob R. (Oklahoma State University, 2010-07-01)
      Winglets have been shown to improve the efficiency of large aircraft at high subsonic speeds, but winglet designs for smaller aircraft like UAVs are unproven. Winglets improve efficiency by diffusing the shed wingtip vortex, ...
