A medium-sized saucer-shaped ducted aircraft， which utilizes “edge electromagnetic driving”， was designed to address the issue of traditional rotary rotor motors being unable to provide sufficient output torque for large-sized blades. To verify the rationality of the design and evaluate the performance parameters of aircraft， structural strength simulation calculations were conducted for typical overload conditions of the aircraft. Furthermore， aerodynamic numerical simulations were performed for hovering and flying attitudes， and electromagnetic force simulation calculations were conducted for the selected electromagnetic coil configuration. The research results show that the edge electromagnetic drive system of the aircraft can output a torque of 3 700 N·m with a torque density of 33.76 N·m/kg， meeting the operational power requirements. Additionally， the aerodynamic capacity of the aircraft design， with a maximum takeoff weight at the one-ton level， was calculated， and the structural strength met the requirements under typical overload conditions， providing reference for the configuration design and driving scheme of medium and large saucer-shaped aircraft.
