The embodiment of the invention provides an overlapped paddle structure and an aircraft. The overlapped propeller structure can be applied to the aircraft, and the overlapped propeller structure comprises a first propeller and a second propeller; the first propeller comprises a first blade, and the first blade rotates to form a first propeller disc; the second propeller comprises second blades, and the second blades rotate to form a second propeller disc; when the first propeller and the second propeller are jointly arranged on a fuselage of the aircraft, the first blades and the second blades are stacked up and down, so that a height difference z is formed between the formed first propeller disc and the formed second propeller disc; the orthographic projection of the first propeller disc and the orthographic projection of the second propeller disc on an overlook plane have mutually overlapped first areas, and the ratio of the area SA of the first areas to the area S1 of the first propeller disc or the area S2 of the second propeller disc is set to be 5%-25%.
本申请实施例提供了一种重叠桨结构以及飞行器;其中,所述重叠桨结构可应用于飞行器,所述重叠桨结构包括有第一螺旋桨和第二螺旋桨;所述第一螺旋桨包括第一桨叶,所述第一桨叶旋转形成第一桨盘;所述第二螺旋桨包括第二桨叶,所述第二桨叶旋转形成第二桨盘;当所述第一螺旋桨和所述第二螺旋桨共同设置在所述飞行器的机身上时,所述第一桨叶与所述第二桨叶为上下叠设,用以使形成的所述第一桨盘与形成的所述第二桨盘之间具有高度差z,且所述第一桨盘与所述第二桨盘在俯视平面上的正投影具有相互重叠的第一区域,所述第一区域的面积SA与所述第一桨盘的面积S1或者所述第二桨盘的面积S2的比值设置为5%~25%。
