为实现长航程、复杂海洋环境中航向高保持能力，本文提出一种高升阻比、分布式推进的新型大翼展水下无人航行器。针对设计目标，基于模块化设计思想，采用仿生构型，完成了大翼展推进与滑翔混合驱动航行器的总体设计，给出了浮力调节系统、重心调节系统、滑翔翼翼型与主尺度、推进器选型及布局等核心单元设计。为提高航行器的生存能力，航行器采用多舱室独立设计及应急抛载单元。基于有限元软件对航行器中耐压壳体进行强度、与刚度的数值与算与分析，结果表明满足规范要求，满足水下1000 m工作要求。本文所提出的分布式滑翔与推进混合驱动滑翔机的设计理念，具有大翼展高升阻比特性，减小滑翔角，满足长航程要求，解决了目前水下航行器航向改变响应速度慢，无法突破导中尺度涡的现象。
In order to realize the high heading capacity in the long range and complex marine environment, this paper proposes a new type of large wingspan unmanned underwater vehicle with high lift resistance and distributed propulsion. Aiming at the design goal, based on the modular design idea and adopting the bionic configuration, the overall design of the large-wing propulsion and gliding hybrid-driven aircraft is completed, and the buoyancy regulation system, the center of gravity adjustment system, the gliding wing type and the main scale, and the propulsion are given. Core unit design such as device selection and layout. In order to improve the survivability of the aircraft, the aircraft adopts multi-chamber independent design and emergency throwing unit; based on the finite element software, the numerical value and calculation and analysis of the strength and stiffness of the pressure-resistant casing in the aircraft, the results show that the requirements are met., to meet the underwater 1000 m working requirements. The design concept of the distributed gliding and propulsion hybrid drive glider proposed in this paper has the characteristics of large wing extension and high lift-to-drag ratio, reducing the glider angle and meeting the requirements of long range. It solves the problem that the current underwater vehicle change direction is slow and cannot be broken. The phenomenon of guiding mesoscale vortices.
