... multirotors is achievable. Moreover, the modular build of the system provides the possibility to adapt currently existing unmanned aircrafts to be converted to the described mothership plane. Practical implications To conduct flight tests and to study encountered problems. Presentation of the unmanned...

...Julius Dahms; Andreas Bardenhagen Purpose This paper deals with the estimation of the necessary masses of propulsion components for multirotor UAS. Originally, within the design process of multirotors, this is an iterative problem, as the propulsion masses contribute to the total takeoff mass...
