Abstract:
This paper developed a synthesis process based on the aerodynamic theories of rotorcraft and fixed-wing aircraft to estimate the performance of electric vertical takeoff and landing （eVTOL） aircraft， which commonly adopt multiple rotors for vertical flight， and propeller and wing for forward flight. Momentum theory analysis and blade element analysis have been well used to analyze flight performance of rotor and propeller. Using the synthesis theory， this study investigated flight performance of 12 eVTOL aircraft including multicopter， lift & cruise， and vectored thrust categories. Flight profiles of driving motor， rotor， and airframe at hovering， climb and descent， and forward flight were estimated. It was also indicated that specifications of the electric propulsion system were defined to match the propeller or rotor to satisfy the flight mission.
