Constrained by the satellites orbits, Satellite Remote Sensing is difficult to achieve timeliness requirements. General aerial manned aircraft Remote Sensing is always delayed by the bad weather. Compared with Unmanned aerial vehicles, unmanned Airship can fly more lower and slower and you can get more clearer image. So it is more suitable for large scale mapping and other engineering requireme...

Abstract Despite many research studies focus on strategies to improve autopilot capabilities and bring artificial intelligence onboard Unmanned Aircraft Systems (UAS), there are still few experimental activities related these vehicle performance under unconventional weather conditions. Air temperature altitudes directly affect thrust power coefficients of small scale propeller for UAS applicati...

The feasibility of using a stand alone Fluidic Thrust-Vectoring (FTV) system for the purpose of longitudinal trim of an unmanned aerial vehicle is the focus of the research presented in this paper. Since the fluidic thrust vectoring requires high pressure secondary air to deflect the engine exhaust gases, this research also provides an analytical toolset for preliminary sizing of a suitable sec...

As the technological and operational capabilities of unmanned aircraft systems (UAS) continue to grow, so too does the need to introduce these systems into civil airspace. Unmanned Aircraft Systems Integration in the National Airspace System is a NASA research project that addresses the integration of civil UAS into non-segregated airspace operations. One of the major challenges of this integra...

When using a team of small unmanned aircraft, with no satellite communications, the operational range of the team is typically limited by line-of-sight communication constraints between an individual aircraft and a ground station, and not the endurance range of the individual aircraft within the team. By using electronic chaining to form a multi-hop communication link using the team, the overal...
