摘要
Abstract
[Objectives]The tunnel catamaran is a special type of planing craft with two planing bodies con-nected in the middle channel.The central channel is lifted by a cyclone which can lift the hull off the surface of the water to achieve a higher speed.It has good rapidity and can quickly enter a stable state during high-speed navigation.The parametric design and resistance performance estimation of a high-speed planing tunnel catamaran play important roles in the development and design of catamarans.[Methods]The parameterized configuration of the hull is carried out by defining the main lines of the planing tunnel catamaran hull with a clamped B-spline curve.The influence of the channel size and deadrise angle of the catamaran on its hull res-istance performance is then studied by setting multiple hull designs in STAR-CCM+.[Results]An optim-ized hull design is obtained with 17.3%resistance reduction compared with the original.[Conclusions]Compared with a planing hull of the same scale and displacement,this study proves that a high-speed planing tunnel catamaran has superior sailing performance under medium and high-speed working conditions.关键词
