The invention discloses a single-beam distributed wing front D box structure of a fixed-wing unmanned aerial vehicle, and belongs to the field of wings of fixed-wing unmanned aerial vehicles. The structure comprises a spar, front half ribs, a leading edge strip, an upper mask, a lower mask and a leading edge; a plurality of front half ribs 2 are arranged between the leading edge strip and the spar along the spanwise direction of the wings, the distribution positions of the front half ribs along the spanwise direction of the wings, the positions of a root rib and a tip rib are x1 = 0 and xN = 0.5 b respectively, the spanwise arrangement position value xn of the rest of the front half ribs is determined by algorithm iteration, and the final result is that the arrangement of the ribs from the root part to the tip part is gradually densified. Each front half rib is of a hollow wing rib frame structure, and the interior of the frame of the front half rib is supported through a main inclined strut, a first-time inclined strut and a second-time inclined strut. According to the arrangement method of the front half ribs, the ratio of the aerodynamic load borne by each wing rib to the chord length value is constant, and the structural efficiency is higher; by designing the shapes of rib inclined struts and lightening holes, the stress characteristics of the ribs are optimized, so that the ribs have higher torsional strength and rigidity, and the whole wings have better torsional performance.

    本发明一种固定翼无人机单梁分布式机翼前D盒结构,属于固定翼无人机机翼领域;包括翼梁、前半肋、前缘条、上蒙板、下蒙板、前缘;若干前半肋2沿机翼展向布置于前缘条和翼梁之间,前半肋沿机翼展向的分布位置,根肋和梢肋的位置分别为:x1=0,xN=0.5b,其余前半肋的展向排布位置值xn由算法迭代确定,最终的结果是从根部到梢部肋的排布逐渐变密。前半肋为镂空的翼肋框架结构,其框架内通过主斜撑、第一次斜撑、第二次斜撑支撑。本发明前半肋的排布方法,使得每个翼肋承受的气动载荷与弦长值之比恒定,结构效率更高;通过设计肋斜撑和减重孔形状,优化了肋的受力特性,使肋本身具有更高的抗扭强度和刚度,进而使整个机翼具有更好的抗扭性能。
