A propeller propulsion system for an aircraft, comprising: a propeller (201); a plurality of electric motors including coaxial drive shafts (222, 223, 224) each nested; and a gearbox (202) having an output shaft (221) to which the propeller (201) is mechanically coupled and an input shaft (211) to which the coaxial drive shafts (222, 223, 224) of the electric motor are mechanically coupled. Thus, the diameter of the propulsion system is reduced in a plane perpendicular to the axis of rotation of the propellers (201). This improves aerodynamic performance and fuel consumption of the aircraft.

    一种用于飞行器的螺旋桨式推进系统,包括:螺旋桨(201);包括各自嵌套的同轴驱动轴(222、223、224)的多个电动马达;以及具有输出轴(221)和输入轴(211)的齿轮箱(202),螺旋桨(201)机械联接到输出轴上,所述电动马达的同轴驱动轴(222、223、224)机械联接到输入轴。因此,在垂直于螺旋桨(201)的旋转轴线的平面中,推进系统的直径缩小。这改善了飞行器的气动性能和燃料消耗。
