A proof of the concept of the in-flight launch of unmanned aerial vehicles in a search and rescue scenario

This article considers the development of a system to enable the in-flight-launch of one aerial system by another. The article discusses how an optimal release mechanism was developed taking into account the aerodynamics of one specific mothership and child Unmanned Aerial Vehicle (UAV). Furthermore, it discusses the Proportional-Integral-Derivative (PID)-based control concept that was introduced in order to autonomously stabilise the child UAV after being released from the mothership UAV. Finally, the article demonstrates how the concept of a mothership and child UAV combination could be taken advantage of in the context of a search and rescue operation.
