Abstract

Abstract: Solar UAV adopts super aspect ratio wing, which has low cruise speed, low wing load and can not fly with excessive structural weight. Therefore, it has strict requirements on the weight of aircraft structure. The wing girder of the wing accounts for most of the weight of the wing structure, so it is necessary to optimize the layer of the composite wig girder to reduce the weight of the wing girder and optimize the structural force transmission effect. First, the finite element model of the half wing of the solar UAV is established, and then the shape, the thickness and the order of the wing girder composite is optimized. After optimization, the weight of the wing girder decreases by 18.68%, the maximum stress decreases by 21.16%, and the tip deformation decreases by 5.9%.

Key words: solar UAV, composite material, layer optimization
