摘　　要：针对传统转轴转子电机难以为大尺寸桨叶提供大输出转矩的问题,设计了一种采用“边缘电磁驱动”的中型碟形涵道式飞行器。为验证设计合理性,并评估飞行器性能参数,对飞行器典型过载工况进行了结构强度仿真计算,对悬停和平飞姿态分别进行了气动数值模拟,并对优选电磁线圈构型进行了电磁力仿真计算。研究结果表明:飞行器边缘电磁驱动系统能输出3700 N·m的转矩,转矩密度33.76 N·m/kg,满足运行动力需求;计算得出该飞行器设计具备一吨级最大起飞质量的气动能力,结构强度满足典型过载工况下的强度要求,为中大型碟形飞行器的构型设计和驱动方案设计提供参考。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 3700 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.
