Analysis of an electrical-powered-ducted-thrust vectoring-flap

For the past few years the Lilium-Jet is fascinating the aviation community. On the one hand its esthetic configurational design approach attracts people, on the other the electric drive and energy storage raises discussions regarding its success. Since only very few technical information of this vehicle is available in the scientific public, the research question is about a better understanding of the design concept. This article presents the approach and results of an experimental study regarding the characteristics and behavior of the Electrical-Powered-Ducted-Thrust-Vectoring-Flap wing concept. Therefore, the first part provides an introduction of the Lilium-Jet based on publicly available information. The following section enrolls a methodology to answer the research question. Based on the description of the methodology some of the results of the wind tunnel tests are presented and discussed indicating, the installation of the ducted fan on the flap provides some significant advantages in the efficiency of the lift generation at different flight states.
