倒V型槽道滑行艇船型的水动力性能研究

On hydrodynamic performance of inverted V-shaped channel planing craft

考虑到高速航行时常规双体滑行艇阻力较大且艇体兴波严重,以及三体滑行艇独特船型所带来的优异快速性和兴波小等优良水动力性能,文章借鉴三体滑行艇的工作原理并应用于双体滑行艇,创新性提出倒V型槽道滑行艇的概念,并进行艇型结构设计和CFD水动力分析。模拟计算结果表明该艇型具有高航速时阻力增加缓慢和纵倾角变化平缓等优点。

The normal catamaran planing craft will generate greater resistance and severe waves on navigating at high speed.However,the trimaran planing craft has good hydrodynamic performance of excellent power performance and small wave making due to its unique hull form.A concept of inverted V-shaped channel planing craft is then proposed in this paper by applying the working principle of the trimaran planing craft onto the catamaran planing craft.It carries out the structural design of the ship hull and the hydrodynamic analysis of the hull form by CFD tools.The numerical simulation shows that the ship hull form has the advantages of the slow resistance increment and the flat trim angle variation in high speed.
