摘要

摘要: 为了提高水下滑翔机的滑翔性能, 将翼身融合布局运用到水下滑翔机外形设计中, 进行了翼身融合水下滑翔机初始外形设计, 并对其进行了参数化建模。通过运动能耗分析, 建立了滑翔机的最大航程计算模型。在此基础上, 以最大航程为目标, 采用代理模型全局优化方法, 对滑翔机进行外形优化设计, 优化结果兼顾了提高升阻比和增大滑翔机体积两方面的需求。通过低速风洞试验验证了优化结果的可行性, 为翼身融合水下滑翔机的研制提供了技术支持和参考。

Abstract: To improve the hydrodynamic performance of an underwater glider, the blend-wing-body (BWB) configuration is applied to the design of an underwater glider. The initial shape design and parametric modeling of BWB underwater glider are carried out. Based on the energy consumption analysis of BWB underwater glider, a calculation model of maximum gliding range is established. Subsequently, taking the maximum range as the goal, the optimization design of the glider is performed by using the global optimization method based on surrogate model. The optimization result takes into account two aspects of improving the lift-to-drag ratio and increasing the volume of the glider. The feasibility of the optimization design is verified by low speed wind tunnel test. This optimization method provides technical support for the development of BWB underwater glider.
