高空滑翔UUV气动参数估算与气动特性分析

摘要

Based on the status that the speed and range of unmanned underwater vehicle (UUV) can not be greatly improved at the same time, this paper advances the conception of high-altitude gliding unmanned underwater vehicle and makes a simple design on the overall layout of it. On this basis, in order to analyze its aerodynamic performance, we estimate its lift coefficient, drag coefficient, pitching moment coefficient, heading static derivative, dynamic derivatives and manipulation derivatives, and draw their curves with the method used on plane and missile design.After this, the lift-drag ratio and stability was analyzed. The results show that this UUV is stable and it has a large lift-drag ratio. We can draw a conclusion that this UUV has a good aerodynamic performance.%研究水下航行器,针对无人水下航行器无法同时大幅度提高航速和航程的现状,为优化无人水下航行器气动特性,增强系统的稳定性,提出了高空滑翔无人水下航行器(UUV)总体气动布局进行设计.对气动特性进行分析,根据飞机和导弹气动参数的估算方法,通过类比的方式,对升力系数、阻力系数、俯仰力矩系数、航向静导数、动导数和操纵导数等主要气动参数进行了仿真,结果得出了相应的变化曲线.利用计算出的参数对其升阻比和稳定性进行了分析.分析结果表明,高空滑翔UUV气动效率高、稳定性好,总体气动特性满足系统精度要求.
