柔性表面减阻技术研究进展

Review of drag reduction technology with flexible surface

船舶或水下航行器移动时,所受阻力主要来自航行器和周围水流之间的相互摩擦的阻力,该阻力大大增加了航行体能量消耗。柔性表面减阻技术是边界层减阻研究领域的热点之一,对节约能源以及潜艇、鱼雷等海军装备的发展具有重要意义。对柔性表面减阻技术的发展进行了归纳和整理,综述了柔性表面减阻技术、柔性材料的特点及主要研究方法,讨论了柔性表面减阻技术在未来的发展趋势。

When movement of ships or other underwater vehicles, the friction resistance mainly comes from the friction between itself and the surrounding water, which can enhance its energy consumption. Drag reduction technology with flexible surface is one hotspot in the field of drag reduction research which has significant value in energy saving and the development of naval equipment such as submarines and torpedoes. Current drag reduction technologies of flexible surface were summed up, The drag reduction technology of flexible surface, features of flexible materials and main experiment methods were reviewed. Future development directions and works were pointed out at the end.
