摘要
高速艇具有体积小、航速高、智能等优点,可以完成搜救、探测、导航和作战等多种任务,广泛应用于军民用领域。研究高速艇的阻力性能对艇体的型线设计和艇体的流体动力学性能分析都显得十分重要。设计一种新型高速艇,通过NUMECA系列软件对不同的高速艇进行数值模拟计算,以研究此类新型高速艇的水动力性能。研究表明:加装水翼或防飞溅条均可增加艇体的升力,使艇体更快地处于滑行状态,安装了防飞溅条的翼滑艇的阻力性能良好。
The high-speed boat has the advantages of small volume, high-speed,and intelligent control,which can complete search and rescue, detection, navigation,combat,and other tasks,and it has been widely applied in military and civilian fields. Particularly,studying the rapidity performance of high-speed boat is of vital importance for the boat design and analysis of fluid dynamics performance. In this paper, a new type of high-speed boat is presented, whose hydrodynamic performance is analyzed and compared with different high-speed boats through numerical simulation in NUMECA software. The results show that hydrofoil and splash-proof strip can improve the lift force of the boat, helping the boat enter the planing state faster. Moreover, it is seen that the gliding-hydrofoil craft with splash-proof strip has good resistance performance.
