The invention belongs to the technical field of aviation electric propulsion, and relates to a propulsion/power generation integrated fan structure of an aviation shaftless rim electric drive system, which mainly comprises two-way flow fan blades (1), a fan blade locking ring (2) and a ring rotor (3), propulsion/power generation integrated fan structures are distributed on the two sides of the aircraft, and reasonable distribution of propulsion and power generation units is facilitated. According to the bidirectional flow fan blades (1), a typical propelling blade shape and a power generation blade shape are fused through a blade shape interpolation fusion method, so that the bidirectional flow fan blades have the characteristics of the two blade shapes, and the power generation efficiency of the fan is greatly improved on the premise that a small amount of propelling efficiency is sacrificed; the blades are made of fiber composite reinforced materials, the weight of the blades is reduced, the mechanical property of the blades is improved, and the strength requirements for the blades during propelling and power generation are met.

    本发明属于航空电推进技术领域,是一种航空无轴轮缘电驱动系统的推进/发电一体化风扇结构,主要包括双向流动扇叶(1)、扇叶锁紧环(2)和环转子(3);采用推进/发电一体化风扇结构分布式布局在飞行器两侧,便于对推进和发电单元的合理分配。双向流动扇叶(1)叶片采用叶型插值融合的方法将典型推进叶形和发电叶形融合起来,使其具有两种叶型的特征,使风扇在牺牲少量推进效率的前提下获得发电效率的大幅提高;叶片采用纤维复合增强材料,实现叶片减重和提高叶片力学性能,满足推进/发电两种功能时对叶片的强度要求。
