This thesis presents a renewed feasibility analysis of an aircraft employing a Propulsive Empennage (PE), focusing on the Delft University Unconventional Configuration (DUUC). Existing aerodynamic and flight mechanics models from earlier DUUC studies are improved and extended to more accurately assess the concept's viability. Two alternative PE positions - one at the tail and one near the front of the fuselage - are analyzed and benchmarked against the ATR72-600. Enhancements include an updated thrust model, revised mass and center of gravity estimations and an improved control vane model. Despite the potential benefits of ducted fans and clean wing configuration, results indicate that increased mass, center of gravity excursion and increased trim drag outweigh the propulsion gains. Ultimately, both DUUC configurations underperform relative to the benchmark, and while the PE concept introduces intriguing design possibilities, it falls short of outperforming conventional turboprop configurations in cruise condition.
