Structure Design of Flapping-Wing and Gliding Underwater Vehicle and CFD Analysis

文章针对海底管线必须定期进行检测这种情况,提出利用扑翼滑翔水下机器人对海底管线进行检测的方案,并对扑翼滑翔水下机器人的总体结构、动力装置和浮力调节装置等进行了结构设计。利用FLUENT软件,对水下机器人在滑翔状态时,仿生扑翼的几种不同俯仰角度和外形尺寸进行了数值分析;结果表明,当仿生扑翼的俯仰角为5°和增大仿生扑翼的展弦比和根梢比时,水下机器人具有较优的大升阻比流体动力性能。

In this paper,using the flapping-wing and gliding underwater vehicle to detect the subsea pipeline is be proposed which for the situation that subsea pipeline must be regularly detect. And the overall structure of the flapping-wing and gliding underwater vehicle,power plant and buoyancy adjusting device is be designed.Using computational fluid dynamics software FLUENT for underwater vehicle in the state of gliding bionic flapping-wing pitching Angle,and a few different shapes of bionic flapping-wing size has carried on the numerical analysis. Results show that when the bionic flapping-wing pitching Angle of 5 °,and increasing the flapping wing aspect ratio and root shoot ratio,Underwater robots hold the Alleged hydrodynamic performance with big lift to drag ratio.
