Aerodynamics

During the conceptual design phase, which involved evaluating a wide range of possible configurations, simplified aerodynamic analysis methods were initially applied. Especially in the context of eVTOL design, geometry plays a significantly greater role compared to conventional aircraft, due to the need to integrate large rotors for vertical flight while simultaneously addressing the so-called balance problem. This refers to achieving a flight-mechanically stable configuration in both vertical and horizontal flight modes.

After narrowing down the concept to a specific aircraft configuration, higher-fidelity aerodynamic methods were used to validate the earlier estimations. These detailed analyses were conducted for both the full-scale vehicle and the flight demonstrator—such as in the SkyCab project—ensuring a robust foundation for further development and system integration.
