Totty, Christopher D. (2022-05)This paper presents the stability analysis of a high speed unmanned aerial system mass simulator fitted with a rocket-assisted take-off (RATO) system. Flight stability characteristics from rocket ignition to rocket burnout ... -
Coolant passage segmentation influence on regenerative-cooling effectiveness for small spacecraft thrusters
Utley, Lucas (2020-05)The purpose of this thesis is to examine the effect of varying the number of cooling passages in a regeneratively-cooled rocket combustion chamber and nozzle analog for a small spacecraft thruster producing 22N (5lbf) ... -
Deployment Dynamics of Inflatable Wings
Loh, Weng Kheong (Ben) (Oklahoma State University, 2008-12-01)Dynamic deployment of inflatable wings were investigated through laboratory, wind tunnel and flight testing. The goal of the research is to design an in-flight morphing wing aircraft using semi-span inflatable wings that ... -
Design and Development of a 3D Printed UAV
Banfield, Christopher P. (2015-07-01)The purpose of this project was to investigate the viability and practicality of using a desktop 3D printer to fabricate small UAV airframes. To that end, ASTM based bending and tensile tests were conducted to assess the ... -
Design and development of a tornado intercept unmanned aerial vehicle
Ross, Andrew Levi (2019-12)Very little data surrounding tornado genesis exists, and this is due in part to the lack of tools necessary to deliver weather-sensing instruments into the severe weather phenomenon. Though current UAS are able to accurately ... -
Design and evaluation of a thermal nozzle for small-scale turbojets
Braun, Joshua Robert (2022-05)This paper presents the design and evaluation of a thermal nozzle for small-scale turbojets. Historically, small-scale turbojets have suffered from poor thermal efficiency and thrust specific fuel consumption (TSFC). This ... -
Design, analysis, and integration of a turboelectric propulsion and power system for unmanned aircraft
Moody, Kylar Julian (2020-05)Electrically powered small unmanned aerial systems face limited range and endurance due to the inherently low energy density of current level of technology batteries. Hybrid gas-electric systems are under development and ... -
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 a Microgravity Uas Test Bed
Hathaway, Jacob Derk (2016-07-01)The ultimate goal is to develop a vehicle that can produce a microgravity environment for space system research within a small to medium sized UAV. This weight class of vehicle provides a platform that is more available ... -
Development of a Microsoft Excel Based Uav Propeller Design and Analysis Tool
Lowe, Trevor Edwin (2015-12-01)QPROP/QMIL were developed by Professor Mark Drela at MIT for use in designing propellers and windmills for various flow conditions. These tools have been used by other graduate students with varying degrees of success, ... -
Effects of electrode material on electrode erosion of electrical discharge machining drill
Copher, Garner (2021-05)This paper presents an experimental investigation of the effects of electrode material and workpiece material on electrode wear and performance of a handheld electrical discharge machining drill. In the aerospace maintenance, ... -
