Recreating Wonder Woman's invisible plane: A quantitative analysis of UAV visual signature manipulation via counterillumination
Stevenson, Luke (Oklahoma State University, 2020-04-24)This study analyzes the effectiveness of an optical camouflage method called counterillumination and its effectiveness on an unmanned aerial vehicle (UAV). Counterillumination is achieved by emitting blue light on the ... -
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 ... -
Soil moisture monitoring with LoRa radios and UAVs
Captain, Levi; Hossain, Fahim; Messenger, Russ; Jacob, Jamey; Taghvaeian, Saleh; Ekin, Sabat (Oklahoma State University, 2021-07-28) -
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 ... -
Vortex ring propagation in confined spheroidal domains and applications to cardiac flows
Samaee, Milad (2019-12)Vortex ring formation is observed in the human cardiac left ventricle (LV) during diastole. Numerous studies to date have examined the intraventricular filling vortex for potential use in the diagnosis of cardiac dysfunction. ...
