摘要
为改善五体船在空载及小摇荡时的耐波性,论文通过在五体船主船体和片体之间加装水翼构造水翼五体船,在此基础上借助耐波性通用软件HydroSTAR对不同水翼攻角水翼五体船及原五体船耐波性计算,并对相关耐波性指标进行对比分析,以此研究水翼五体船的攻角优化问题。通过对比研究发现,水翼五体船的纵摇幅值、横摇幅值及垂荡幅值明显低于五体船,且在低频波段NACA4415翼型水翼五体船最优攻角在10°左右。
To improve the seakeeping in small waves and no-load conditions, a new Hydrofoil-Pentamaran with four hydrofoils between main hull and accessory hulls is put forward in the paper. The seakeeping indexes of normal Petamaran and the Hydrofoil-Pentamaran with different hydrofoil angles are analyzed by HydroSTAR software. We can find from the analysis that the pitch, roll, heave will be reduced by the hydrofoil between main hull and accessory hull and the bestper-formance angle of NACA4415 hydrofoil is about 10°.
