水下滑翔机水动力外形研究综述

Overview on the hydrodynamic performance of underwater gliders

水下滑翔机是一种将传统的浮标技术与水下机器人技术相结合而研制成的新型自治水下机器人,具有作业时间长、航行距离大、建造和使用成本低等优点。水下滑翔机主要用于海洋环境长时间、大范围的实时监测,因此要求其具有优良的水动力性能。文章简要回顾了水下滑翔机的发展历程,重点介绍了其水动力外形方面的研究进展,并简要介绍了混合驱动和飞翼等概念在水下滑翔机上的应用研究,最后对水下滑翔机未来的发展趋势进行了展望。

Abstract：Underwater glider is a new kind of AUV which takes advantages of traditional buoys and under- water robots. It has many merits such as long-range, extended-duration and low costs. Well hydrodynamic performance is necessary for an underwater glider for its usage of ocean monitoring over a wide temporal and spatial range. The history of underwater glider development is reviewed in this paper, together with the development trends of its hydrodynamic performances. Moreover, the application study of concepts such as hybrid propulsion and flying wings on underwater gliders is briefly introduced. Finally, the prospects of un- derwater gliders are proposed.
