| 摘 要： | 依据线性兴波阻力理论和兴波干扰原理对加装消波水翼船型的兴波阻力计算方法和降阻效果进行了研究．用所提方法对一加装消波水翼的高速圆舭模进行了计算，理论计算结果与模型试验结果的比较表明，建立的带消波水翼船型兴波阻力计算方法基本上可实用于消波水翼设计以及该类艇兴波阻力的估算．带消波水翼艇与无消波水翼艇阻力比较表明，加装消波水翼后，傅汝德数Ｆｎ在０．５５～０．８５区间，兴波阻力理论值和剩余阻力试验值都显著降低，当Ｆｎ＝０．６时兴波阻力理论值降低了１６．１％，剩余阻力试验值降低了２５％．

| Abstract: | A computation method of wave resistance to the high speed round bilge boat with anti wave hydrofoil and the resistance deduction effect of this anti wave hydrofoil is studied, based on the linear wave resistance theory and the interference phenomenon of ship waves. The computation is executed on a high speed round bilge boat model by the present method. Comparing the results of the theory with the model tests, the results show that this method is general practicable to the anti wave hydrofoil design and the wave resistance evaluation of this ship form. The resistance reduction effect of the anti wave hydrofoil is verified. Both wave resistance and residual resistance are apparently reduced when Froude number Fn =0.55~0.85; the theory wave resistance is reduced by 16.1 % and the residual resistance by 25 % when Froude number Fn =0.06. |
