摘　　要：针对传统飞艇外形设计过程中仅将阻力作为优化目标的问题,先参照多学科优化设计理念,在原有阻力模型的基础上,引进体积与表面积对飞艇外形优化设计的影响,建立飞艇优化的数学模型,构建优化框架,再结合最优化设计中的复合形法,依据双向并行探索理念,提出一种改进复合形法,并将其运用到飞艇外形优化中,结合优化值给出不同需求下的优化设计方案,最后结合实际算例仿真分析得出改进复合形法对于飞艇外形的优化是可行的结论。In view of the problem of only considering resistance as the optimization objective in the traditional air-ship shape design process,this paper first refers to the concept of multidisciplinary optimization design,and introduces the influence of volume and surface area on the shape optimization design of airship based on the original resistance model.Then,this paper establishes the target function of airship optimization,and constructs the airship shape optimi-zation process framework.In addition,this paper proposes an improved composite form method by combining the com-posite form method and the concept of bidirectional parallel exploration in optimization design,and it is applied to the optimization of the airship.Moreover,this algorithm can provide targeted optimization design scheme according to dif-ferent needs.Finally,it is concluded that the optimization algorithm based on the improved composite form method is feasible for the optimization of airship shape.
