【摘要】 本文分析了几艘实用双体船的模型试验资料并以图表的形式表达了双体干扰阻力分数K_r与间距比K/b、付汝德数F_n和棱形系数C_P的关系;以及片体剩余阻力系数C_r0与F_n和C_P的关系。借助这些图表可近似估算双体船阻力。适用范围:L/b=8.0～13.0;b/d=1.48～3.08;C_b=0.46～0.58;C_P=0.55～0.65;K/b=1.6～3.0。更多还原

【Abstract】 This paper analyses the model test results of some conventional catamarans, and gives graphically the relationship between interference resistance fraction K_r and separation ratioK/b; Froude-number F_n and prismatic coefficient C_p; and the relationship between residual resistance coefficient C_r0 and F_n or C_p. These graphs can be used for estimating the resistance of catamaran at the stage of preliminary design.更多还原
