Intent Communication Between Autonomous Vehicles and Pedestrians
Matthews, Milecia (2016-05-01)When pedestrians encounter vehicles, they typically stop and wait for a signal from the driver to either cross or wait. What happens when the car is autonomous and there isn't a human driver to signal them? This paper seeks ... -
Investigation of Low-Profile Vortex Generators via Computational Methods
Wilson, Trevor (2019-07)A unique low-profile vortex generator, termed the Conformal Vortex Generator (CVG), has recently been discovered to provide fuel saving of greater than 1% on commercial aircraft. The CVG is an adhesive backed film that ... -
Investigation of Low-Profile Vortex Generators via Experimental Methods
KC, Real (2019-07)A novel low-profile vortex generator has recently demonstrated fuel savings of 1% on commercial aircraft. It has been termed a Conformal Vortex Generator (CVG) and consists of a backward facing step where the chord position ... -
Modeling and failure analysis of composite I-beams for UAV wing spar design
Watkins, Zachary Taylor (2021-05)In unmanned aerial systems (UAS), the composite I-beam using carbon fiber caps and a cross-grain balsa shear web is often used for the main spar. This manufacturing method is underdeveloped in analysis causing engineers ... -
Modular Autopilot Design and Development Featuring Bayesian Non-parametric Adaptive Control
Stockton, Jacob (Oklahoma State University, 2014-12-01)Over the last few decades, Unmanned Aircraft Systems, or UAS, have become a critical part of the defense of our nation and the growth of the aerospace sector. UAS have a great potential for the agricultural industry, first ... -
Monitoring Yellow Floating Heart (Nymphoides peltata) on Lake Carl Blackwell via Remote Sensing
Angle, Stephen (2019-07)Yellow floating heart (Nymphoides peltata) is an invasive floating-leaf aquatic plant. This species forms dense mats of rhizomatous vegetation that can produce tens of thousands of seeds per square meter. These seeds spread ... -
Near Wall Structure and Deviation from Equilibrium in Wavy Channel Turbulence
Khan, Saadbin (2019-07)The structure of turbulent flow over non-flat surfaces is a topic of major interest in practical applications in both engineering and geophysical settings. A lot of work has been done in the fully rough regime at high ... -
Physical Model Studies of Metachronal Swimming
Lai, Hong Kuan (2016-12-01)Aquatic crustaceans such as copepods, krill and shrimp spend most of their life cycle swimming. These organisms have been studied for their ecological importance, as they form a crucial link between smaller phytoplankton ... -
Scaling effects of 5- to 13-kw turboelectric unmanned aircraft power systems
Runnels, Timothy Raymond (2022-05)This thesis details ground tests of three different turboelectric systems for unmanned aircraft applications based on existing 5-kW, 7-kW and 13-kW turbine engines. The motivation for this study is the continuing emergence ... -
Sensor fusion to improve state estimate accuracy using multiple inertial measurement units and its application to wind estimation
Patel, Ujjval Nirmalkumar (2021-12)On-board state estimation is a persistent challenge to fielding unmanned aerial systems (UAS), particularly when global positioning system (GPS) measurements are not available. The dominant estimation tool remains the ... -
Trajectory Optimization of Meteorological Sampling
Azartash-Namin, Kaevon Alexander (2019-07)Swarming involves controlling multiple unmanned aerial systems or UAS in formation through the use of controls and algorithms. Swarm systems may be distributed and not rely on a central controller. As a result, this gives ... -
Turboprop performance and acoustic evaluation for a small unmanned aircraft variable-cycle engine
Durkee, Matt (2019-05)Range and endurance of small unmanned aircraft systems (sUAS) driven by gas turbine engines are constrained by high thrust specific fuel consumption (TSFC) resulting from low overall efficiency. This study evaluates the ...
