“…• Large flight envelope due to transformation This seems to be the reason that, despite research efforts in tilt-wing VTOL aircraft and convertiplanes since mid of the 20 th century [4,11,22,23], no established aerodynamic model exists. Indeed, propelled by diverse tools for fluid simulation, increased efforts have been made lately to understand the intricate aerodynamics of tilt-wing and multirotors in general [8,16,[24][25][26]. In accordance with this trend, finding a representative aerodynamic model can be identified as the most demanding challenge for the work on tilt-wing aircraft, especially from a flight control perspective when considering the transition maneuver.…”

“…Consequently, a good compromise of hover and cruise flight efficiency can be achieved. Thus, compared to other VTOL systems like multicopters or lift+cruise configurations, tilt-wing VTOL aircraft feature higher airspeed and extended flight ranges in a trade-off with mechanical complexity and complex flight control systems [5,8,9].…”

Electric vertical take-off and landing (eVTOL) aircraft enable new transport options in regional and urban air mobility. One promising but only little investigated and understood subcategory comprises tilt-wing eVTOLs. They offer high efficiency and long flight ranges but come with a trade-off in increased complexity. Consequently, a critical step towards market entry is the development of mature and safe hybrid pilot-autonomy control systems, including fault detection, identification, and recovery (FDIR) concepts. That requires a mid-fidelity dynamic model with sufficient accuracy, which is not yet available despite a long history of tilt-wing research. Without a representative model, no detailed analysis and identification of a trimmed transition trajectory could be performed. This, however, is a crucial step in the development of a control system. We approach the problem by applying and combining current modeling approaches. Furthermore, a trim analysis of different flight phases, including the transition, is conducted. The identified model lays the foundation for a representative and detailed development and investigation of future control designs, bringing tilt-wing eVTOLs closer to airworthiness.

“…Bacchini and Cestino (2019) examined a variety of eVTOL design concepts and confirmed that winged architectures best serve long-range missions (Bacchini & Cestino, 2019). Wilke (2020) found that the wing benefits both hovering and cruise modes because it acts as a stator to increase the rotor efficiency (Wilke, 2020).…”
