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 ... -
Efficacy of SOLIDWORKS Flow Simulation for use in thermal management and propulsion systems cooling of unmanned aircraft systems
Reavis, Karis L. (2021-05)As the capabilities of unmanned aircraft systems (UAS) expand, optimizing the thermal management designs become increasingly important. SOLIDWORKS Flow Simulation is a powerful and accessible tool that has the potential ... -
Investigation of lightweight concepts for low-frequency performance enhancement in acoustic liners
Svetgoff, Alexander A. (2021-05)Acoustic liners are extensively used to reduce noise emitted by aircraft engines. However, conventional acoustic liners are largely ineffective for low-frequency noise content (<~1000 Hz) due to impractical mass and volume ... -
Investigation of Natural and Anthropomorphic Sources of Atmospheric Infrasound
Threatt, Arnesha Renee' (2016-12-01)Numerous geophysical and anthropogenic events emit infrasonic frequencies (<20 Hz), including volcanoes, hurricanes, earthquakes and tornadoes. These sounds, which cannot be heard by the human ear, can be detected from ... -
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 ...
