A remotely piloted aircraft system in major incident management: concept and pilot, feasibility study. [PDF]

BMC Emerg Med, 2015
Major incidents are complex, dynamic and bewildering task environments characterised by simultaneous, rapidly changing events, uncertainty and ill-structured problems. Efficient management, communication, decision-making and allocation of scarce medical resources at the chaotic scene of a major incident is challenging and often relies on sparse ...

A Method for Improved Flight Testing of Remotely Piloted Aircraft Using Multisine Inputs

Aerospace, 2020
Unless a segregated airspace and the corresponding clearances can be afforded, flight testing of remotely piloted aircraft is often done near the ground and within visual line-of-sight. In addition to the increased exposure to turbulence, this setup also

Hybrid Propulsion Systems for Remotely Piloted Aircraft Systems [PDF]

Aerospace, 2018
The development of more efficient propulsion systems for aerospace vehicles is essential to achieve key objectives. These objectives are to increase efficiency while reducing the amount of carbon-based emissions. Hybrid electric propulsion (HEP) is an ideal means to maintain the energy density of hydrocarbon-based fuels and utilize energy-efficient ...
