水下滑翔机高效滑翔水动力性能研究

Hydrodynamic Performance of Autonomous Underwater Glider with High Efficiency

借鉴海洋生物高效巡游的运动方式,在传统水下滑翔机概念设计的基础上引入可扭转水翼的概念设想.水翼可根据滑翔机的不同运动姿态,自主调节水翼扭转角,使得水平方向能量输出最大,从而提高航程和续航力.分析了扭转角对滑翔机水动力性能的影响,按自定义的滑翔效率给出了最优扭转角.研究成果可为UUV的发展提供技术支撑和指导.

In this paper,the concept of rotatable hydrofoil is introduced by referring to efficient swimming of sea creatures.The torsion angle of the hydrofoil can be adjusted,so as to improve the gliding endurance and range.Influence of torsion angle on the hydrodynamic performance of the underwater glider is analyzed and the optimum torsion angle is given according to the self-defined gliding efficiency.Conclusion acquired in this article can provide technical support and guidance for the development of unmanned underwater vehicles.
