From Formal Requirements to Highly Assured Software for Unmanned Aircraft Systems [PDF]

Operational requirements of safety-critical systems are often written in restricted specification logics. These restricted logics are amenable to automated analysis techniques such as model-checking, but are not rich enough to express complex ...

Dynamics of a Small Unmanned Aircraft Parachute System

Journal of Aerospace Technology and Management, 2018
Parachute Systems (PS) can be readily used by small Unmanned Aircraft Systems (UAS) for risk mitigation and aircraft recovery. To date there has been limited research into the fundamental dynamics of parachutes at low Reynolds numbers,with existing ...

COUNTERING UNMANNED AIRCRAFT SYSTEMS

, 2019
Since 2015, the unmanned aircraft system (UAS) market has exploded; once an exclusively military domain, it is now also aimed at the private and public sectors. As a consequence, the availability of inexpensive UAS platforms that can be weaponized or outfitted with surveillance equipment has also become an attractive tool to terrorists and criminals ...
