The propeller comprises a propeller hub and a plurality of blades, the blades are fixed to the propeller hub, each blade comprises a supporting framework and a blade surface wrapping the supporting framework, the supporting framework comprises a wing spar and a wing rib, the wing spar extends in the first direction, the wing rib extends in the second direction, the first direction is the length direction of the blades, and the second direction is the length direction of the blades. The second direction is perpendicular to the first direction, the multiple wing ribs are arranged at intervals in the first direction, the center of each wing rib is provided with an installation hole for the corresponding spar to penetrate through, the wing ribs and the spar are all made of carbon fiber multilayer plates, the carbon fiber multilayer plates are formed by laying multiple layers of carbon fiber cloth in a stacked mode, and the carbon fiber cloth is arranged in the installation hole. And two adjacent layers of carbon fiber cloth are connected in a bonding manner. According to the propeller, the supporting framework is made of the carbon fiber material, the wing spar is arranged to improve the structural strength of the propeller blades, the weight of the propeller blades can be reduced, meanwhile, the structural strength of the propeller blades can be guaranteed, the reliability of the propeller is improved, and the service life of the propeller is prolonged.

    本申请关于一种螺旋桨及无人机,螺旋桨包括桨毂和多个桨叶,多个桨叶固定于桨毂上,桨叶包括支撑骨架和包覆于支撑骨架的叶面,支撑骨架包括翼梁和翼肋,翼梁沿第一方向延伸,翼肋沿第二方向延伸,第一方向为桨叶的长度方向,第二方向垂直于第一方向,翼肋的数量为多个,多个翼肋沿第一方向间隔设置,每个翼肋的中心均设置供翼梁穿过的安装孔,其中,翼肋和翼梁均由碳纤维多层板制成,碳纤维多层板由多层碳纤维布层叠铺设,相邻的两层碳纤维布之间粘接连接。本申请的螺旋桨中,支撑骨架采用碳纤维材质,并且设置翼梁提高桨叶的结构强度,有利于减轻桨叶重量,同时还能够保证其结构强度,提高螺旋桨的可靠性和使用寿命。
