Design and Simulation Analysis of the Tail Rudder for Pump-jet Propelled Underwater Glider

摘要:

泵喷推进水下滑翔机是在传统浮力驱动型水下滑翔机基础上配置泵喷推进器发展而来的一种混合驱动型水下滑翔机。为了提高其机动性，泵喷推进水下滑翔机采用尾舵式结构设计方案。采用数值仿真方法，针对尾舵翼型、展弦比、后掠角、舵轴位置等相关参数开展研究，完成了尾舵水动力结构设计。利用动力学仿真方法，对比分析了泵喷推进水下滑翔机与同尺度下横滚式水下滑翔机的转向性能，仿真结果表明： 尾舵式结构的转向性能明显优于横滚式。

Abstract:

Pump-jet propelled underwater glider is a kind of hybrid driven underwater glider developed on the basis of traditional buoyancy driven underwater glider with pump-jet propulsion. In order to improve its maneuverability，the pump-jet propelled underwater glider adopts the tail-rudder structure design. In this paper， numerical simulation method is adopted to study the rudder airfoil，aspect ratio，sweep angle，rudder shaft position and other related parameters of the rudder，and the hydrodynamic structure design of the rudder is completed. Using dynamics simulation method，the turning performance of pump-jet propulsion underwater glider and roll underwater glider at the same scale are compared and analyzed. The simulation results show that the turning performance of tail-rudder structure is obviously better than that of roll underwater glider.
