The invention discloses an unmanned aerial vehicle and a wing thereof, the wing comprises a main beam structure and a shape maintaining structure, the main beam structure comprises a plurality of layers of beam frames distributed at intervals in the vertical direction, and each beam frame comprises a plurality of longitudinal beams extending in the length direction of the wing; every two adjacent longitudinal beams of the beam frame on the same layer are connected through a connecting beam, every two adjacent beam frames are connected through a web beam, and at least the beam frame on the uppermost layer and the beam frame on the lowermost layer are connected with the shape maintaining structure. According to the arrangement, the main beam structure adopts a space truss structure formed by combining a plurality of split type longitudinal beams, connecting beams and web beams, the strength and the rigidity are relatively high, so that the wing can keep enough rigidity in the working process, and compared with the prior art, the main beam structure is lighter in mass and can better meet the design requirement of light weight.

    本发明公开一种无人机及其机翼,其中,该机翼包括主梁结构和维形结构,所述主梁结构包括沿上下方向间隔分布的若干层梁架,各所述梁架均包括沿所述机翼的长度方向延伸的若干纵梁,同一层所述梁架的相邻两所述纵梁之间通过连梁相连,相邻的两所述梁架之间通过腹梁相连,至少最上层的所述梁架以及最下层的所述梁架与所述维形结构相连。如此设置,主梁结构采用若干分体式的纵梁、连梁以及腹梁组合而成的空间网架结构,强度和刚度均较高,使得机翼在工作过程中可以保持足够的刚度,且相比于现有技术,上述主梁结构的质量更轻,更能够满足轻量化的设计要求。
