斧艏线型在高速艇中的应用

Application of Axe Bow Line in High Speed Craft

高速艇线型优化是方案设计的重点,采用CFD方法,对适用于排水型高速艇的斧式直首线型进行分析研究。通过对某常规高速船线型进行艏部改型,改型中主要控制船体中部以及尾部保持一致,仅将艏部改为斧艏线型,比较静水力性能以及水动力性能,包括快速性和耐波性等,分析两种线型的优劣。采用RANS方法以及势流的方法进行计。根据文章采取的不同减阻方案,优化后的线型具有较为明显的减阻效果,并且斧艏线型具有更优秀的耐波性。

High-speed boat line optimization is the key point of the program design.Based on computational fluid dynamic(CFD)method,research the axe fore hull line suitable for the displacement high-speed boat.To keep the same,only change the bow line,compare the hydrostatic performance and hydrodynamic performance,including rapidity,seakeeping.and analyze the advantages and disadvantages of the two lines types.Use the RANS method and the potential flow method to calculate.According to the different drag reduction schemes adopted,the optimized line shape can achieve a obvious drag reduction effect,and the bow line shape has better seakeeping.
