Experimental observation of boundary layer and movement of topographically varying desert dunes with unmanned systems
(2022-12)
Desert dunes offer unique geophysical interactions, and these eolian dominant interactions occur over a significant portion of earth surfaces. There are multiple factors that determine the direction and shape of these ...
Development and evaluation of a 360° differential pressure gust sensor for extreme weather environments
(2022-07)
Measuring rapidly fluctuating high wind speeds and direction in the extreme weather environments of severe storms proves to be a difficult task with current sensors. For example, mechanical anemometers do not provide ...
Primary breakup of liquid sheets in crossflow and liquid jets in gaseous coflow
(2022-05)
This thesis discusses the breakup of liquid sheets under the influence of crossflow and the breakup of micro-liquid jets in coflow air. The breakup of liquid jets and sheets is important for many applications, e.g., ...
Evaluation of a dual-mode, turbojet-turboprop engine for unmanned aircraft
(2022-05)
This paper provides experimental feedback on the feasibility of a small-scale, dual-mode turbojet to turboprop engine. The engine used for testing was a KingTech K45-TP. Key parameters focused on for this experiment were ...
Finite element analysis for the design of novel ceramic propellers
(2022-12)
Ceramics are stiff, lightweight and less prone to deflection. However, ceramics have not historically been used in propeller applications. Little is known about how ceramics will react to the various loading situations of ...
Identification of weather information gaps for general aviation and uncrewed operations
(2022-07)
Uncrewed Aircraft Systems (UAS) represent a rapidly growing industry, with a market value of $20.8 billion in 2021 projected to grow to half a trillion dollars in 2028, and Urban Air Mobility is projected to grow from $3 ...
Watch your step! Towards predicting osteoarthritis onset based on side-to-side imbalances
(2022-05)
Osteoarthritis (OA) is a debilitating disease characterized by the erosion of articular cartilage at the extremity of bones. OA contributes to economic burdens, pain, and abnormal locomotion to accommodate for loss of ...
Evaluation of granular distribution and propellant grain length on tri-modal ammonium perchlorate solid rocket motors
(2022-05)
This paper presents an evaluation on the effects that variances in ammonium perchlorate particles size, total aluminum content ratio, and solid rocket motor geometry has on tri-modal ammonium perchlorate composite solid ...
Development of a robotic arm-gantry simulator with probabilistic inference based control
(2022-05)
Robotic arms can perform repetitive tasks with high speed, accuracy, and precision, making them highly suitable for applications that are monotonous or require a high degree of precision. Such applications include industrial ...
