A Six DOF nonlinear model of a large unmanned aerial system is developed using two competing approaches in modeling aircraft with V-tail configuration. In one approach the V-tail is projected into horizontal and vertical planes and the aircraft airflow angles, angle of attack and sideslip angle, are used for analysis. This approach has been successfully used to model aircraft with low horizontal tail...
While incremental steps are being taken to integrate unmanned aircraft systems (UAS) into the various national airspace systems, much work remains to establish appropriate regulatory infrastructure that allows UAS larger than 55 lb to operate for commerce or hire. The magnitude of that effort is compounded by the wide-ranging variety of UAS types and possible applications, as well as the diversity...
The last decade has witnessed both the growth in Remotely Piloted Aircraft (RPA) numbers and the introduction of the Airbus A380, the largest passenger aircraft to enter commercial service. Both introduce extremes at either end of the spectrum for weight and wingspan: into an Air Traffic Management (ATM) System where wake vortex separation minima have been unchanged for three decades. However, airport...
