为实现水下滑翔机低功耗、长航程的目标, 提高水下滑翔机升阻比是切实可行的手段之一。采用翼身融合布局设计了一款翼身融合水下滑翔机(blended-wing-body underwater glider, BWBUG), 利用NURBS样条曲线构建BWBUG的精细化参数模型, 以升阻比为优化目标, 运用组合优化算法, 开展BWBUG的多参数优化研究, 建立优化算法与黏流软件接口, 优化过程中直接耦合调用水动力计算, 大大提高了优化效率。结果表明, 优化后的BWBUG模型升力系数提升了0.58%, 阻力系数降低了10.22%, 升阻比提升12.01%, 水动力综合性能提升11.99%。文中所建立的优化方法对提高水下航行器构型优化具有重要的指导意义。
