LAYOUT OPTIMIZATION OF COMPOSITE UAV WING STRUCTURE BASEDON TWO-LEVEL OPTIMIZATION METHOD

Abstract

Abstract: In order to reduce the weight of wing structure of composite unmanned aerial vehicle(UAV), a method of two-level optimization which uses MSC.PATRAN and MSC.NASTRAN is proposed in this paper. In the first level, a response surface method is used to optimize the location of the longitudinal wing spars. In the second level, a genetic algorithm is used to optimize the lay parameter of wing structure. As an example, a layout optimization of one type of high aspect-ratio wing structure is calculated. The result shows that about 25% weight of wing structure is reduced. It can be concluded that the two-level optimization method can significantly reduce the wing structure weight, which can satisfy the design requirements.
