Comprehensive Modeling of Electric Propulsion System for High-fidelity eVTOL-AAM Flight Simulation

In recent years, Advanced Air Mobility (AAM) has emerged as a transformative and sustainable solution for densely populated urban areas, leveraging electric Vertical Takeoff and Landing (eVTOL) aircraft. As the demand for eVTOL aircraft increases, the need for high-fidelity flight simulation becomes essential. Electric propulsion system plays a central role in the flight dynamics of eVTOL aircraft. This research develops a comprehensive model of the electric propulsion system for eVTOL flight simulation. The model includes a detailed mathematical representation of each component and its contribution to the vehicle's flight dynamics. The reliability of this fully integrated system is evaluated through a case study involving a scaled prototype AAM aircraft, incorporating both ground-based and flight test scenarios. The agreement between simulation results and experimental data demonstrates the model's robustness and its significant potential for enhancing virtual flight certification and advancing digital twin technologies in AAM.
