Assessing Noise Emissions of Different Drones in Representative Flight Maneuvers

Kurzfassung

This scientific publication focuses (i) on the specifications of the various drones used in this study, (ii) on the specifics of the varying flight maneuvers undertaken in the flight tests and (iii) on sharing the overall flight test experience. In the course of two different flight test campaigns conducted at DLRs National Experimental Test Center for Unmanned Aerial Systems in Cochstedt (Germany) in December 2020 and July 2021, numerous acoustical measurements have been recorded and later analyzed. Within this research initiative, the German Environmental Agency was responsible for providing the required measurement equipment, specifying the required UAV flight routes and analyzing the obtained research data.
