Aerodynamic Configuration and Power System Design of Tilt Rotor Flying Car

With the acceleration of urbanization and increasing traffic congestion, flying cars have emerged as a promising solution by combining aerial and ground transportation capabilities. This paper focuses on the tilt-rotor flying car, which integrates the vertical takeoff and landing ability of a helicopter with the efficient cruising performance of a fixed-wing aircraft. The transition between flight modes introduces complex aerodynamic and dynamic challenges that directly impact safety and operational efficiency. This study presents the aerodynamic design of a two-rotor tilt-rotor configuration, carefully optimizing wing parameters including airfoil type, planform shape, aspect ratio, and sweep angle. Computational fluid dynamics simulations using STAR-CCM+were employed to verify the design. Additionally, a hybrid power system was developed, incorporating an engine, drive motors, battery, and transmission system, with simulations conducted to ensure proper performance matching. Using AVL Cruise and SUAVE software, comprehensive simulations were performed to evaluate both ground and flight performance. The results demonstrate the feasibility of the tilt-rotor flying car design and provide a foundation for further optimization. This research contributes valuable insights into the development of future flying vehicles, supporting advancements in urban mobility and low-altitude transportation.
