A Numerical Vortex Approach To Aerodynamic Modeling of SUAV/VTOL Aircraft
A combined wing and propeller model is presented as a low-cost approach to preliminary modeling of slipstream effects on a finite wing. The wing aerodynamic model employs a numerical lifting-line method utilizing the 3D vortex lifting law along with known 2D airfoil data to predict the lift …

UAV Communications: Spectral Requirements, MAV and SUAV Channel Modeling, OFDM Waveform Parameters, Performance and Spectrum Management
… importance of Micro UAVs (MAV) and Small UAVs (SUAV), the thesis determines spectral requirements for control and non-payload communication (CNPC). We show that spectral efficiency, particularly in the downlink, is critical to the large-scale deployment of UAVs. Due to the limited range of small …

Remote Terrain Navigation for Unmanned Air Vehicles
… for which small unmanned aerial vehicles (SUAVs) are well suited, including surveillance, reconnaissance, search and rescue, convoy support, and short-range low-altitude perimeter patrol missions. As technologies for microcontrollers and small sensors have improved, so have the capabilities …

UAS Risk Analysis using Bayesian Belief Networks: An Application to the VirginiaTech ESPAARO
Small Unmanned Aerial Vehicles (SUAVs) are rapidly being adopted in the National Airspace (NAS) but experience a much higher failure rate than traditional aircraft. These SUAVs are quickly becoming complex enough to investigate alternative methods of failure analysis. This thesis proposes a method …

Future Forests of Bainbridge Island; Climate Change Vulnerability and Continuing Progressive Management
… changes using a small Unmanned Aerial Vehicle (sUAV) drone and mapping technologies. Suggested management action is focused on tree selection and planting strategies, presenting a catalog of suitable species across a “progressive management” intervention spectrum.

An Evidence Theoretic Approach to Design of Reliable Low-Cost UAVs
Small unmanned aerial vehicles (SUAVs) are plagued by alarmingly high failure rates. Because these systems are small and built at lower cost than full-scale aircraft, high quality components and redundant systems are often eschewed to keep production costs low. This thesis proposes a process to …

Hydromorphological evolution of a restored river; a case study in the Upper River Eden catchment
… acquiring by a small unmanned aerial vehicle (sUAV) facilitated topographical and photogrammetric data (at the centimeter scale), used to characterise habitat, assess sediment and sediment flux within the restored reach. The results show rapid initial response; erosion and deposition at the …

A Biomimetic, Energy-Harvesting, Obstacle-Avoiding, Path-Planning Algorithm for UAVs
… paths of two small Unmanned Aerial Vehicles (sUAV) in the 500 kg and 250 kg class. The results show that, in mountainous regions, substantial energy can be recovered, depending on topography and wind characteristics. For the examples presented, as much as 50% of the energy was recovered for a …

The behavior of sUAS under explosive loading conditions and implications for safe operating procedures
… (microseconds) high temperatures. In all, the sUAV tested was found to be very robust. A theoretical mathematical model showing the relationship between the distance from the blast and the peak reflective pressure experienced by the drone is provided. Simple rules of thumb for safe standoff …

Applications of Search Theory to Coordinated Searching by Unmanned Aerial Vehicles
… planning for Small Unmanned Aerial Vehicles (SUAVs). A typical search often requires that more than one target be located. Accordingly, a method is presented to locate multiple targets in three dimensions, as well as to differentiate between them. However, significant error can be present when …
