Flight Performance and Propulsion department of Aerospace Engineering, Delft University of Technology has proposed an effective and sustainable solution to the main challenges aviation is currently facing, namely the raising concerns regarding the environmental and health impact of the industry. Delft University Unconventional Concept (DUUC) has a conventional fuselage coupled with clean wing that is expected to facilitate laminar flow. Furthermore, two ducted propellers are positioned aft on the tail cone installed via pylons. The ducts are designed such that they perform multiple functions: they provide sufficient longitudinal and directional stability, resulting in no tail-configuration and possible weight reduction, improve propulsive performance by increasing static thrust, assure higher safety in blade-loss and reduce cabin and community noise. This research proposes a physics-based design-sensitive weight estimation method of such propulsive empennage suitable for conceptual design phase.
