摘要
基于模块化思想,设计一种小型水下航行器,该航行器共分为艏舱、前侧推进舱、前浮力舱、主控舱、后浮力舱、后侧推进舱和艉舱7个舱室,并在航行器上安装可拆卸式滑翔翼板,由滑翔翼提供向上升力。设计完成后,建立航行器的三维数值仿真模型,采用CFD软件对其进行水动力学性能预报,分析水下航行器的流场分布以及不同攻角下的升力和阻力特性,并通过试验验证数值仿真结果的准确性,为新型水下小型航行器的设计提供研究思路。
A small underwater vehicle is designed based on the idea of modularization,which is divided into seven cabins:bow cabin,front propulsion cabin,front buoyancy cabin,main control cabin,rear buoyancy cabin,rear propulsion cabin and stern cabin.The detachable gliding wing is installed on the vehicle,and the gliding wing provides lifting force.After completing design,the three-dimensional numerical model of underwater vehicle is established.And the hydrodynamic performance of underwater vehicle is predicted by CFD.The flow field distribution of underwater vehicle and the lift and drag characteristics at different angles of attack are analyzed.The accuracy of numerical simulation results is verified by experiments,which provides research ideas for the design of new underwater small vehicle.
