带阻流板和水平翼的高速深V型复合艇新构型

New Configuration of High Speed Deep V Composite Boat with Interceptor and Horizontal Fin

以某高速深V型快艇为研究对象,采用阻流板与水平翼组合附体的方式对其进行计算流体动力学(CFD)水动力性能数值模拟。对该复合快艇在过渡状态和滑行状态下的阻力性能及航行姿态进行评估;结合自由面兴波和艇体表面压力分布情况,获得一种深V型复合艇构型设计方案。该复合艇的运动姿态相比以往的快艇得到大幅改善,在过渡状态下模型的总阻力值比原方案减少18.97%。

Taking a high speed deep V boat as the research object,the numerical simulation of computational fluid dynamics(CFD)hydrodynamic performance is carried out by using the combination of interceptor and the horizontal fin.The resistance performance and sailing posture of the composite boat in the state of transition and glide are evaluated.Combined with the free surface wave and the surface pressure distribution of the hull,a deep V composite boat configuration is obtained.Compared with the previous speedboat,the motion posture of the composite boat is greatly improved.In the transient state,the total resistance value of the model is 18.97%lower than the original scheme.
