深V型艇与圆舭型艇的阻力和耐波性比较

对高速排水型艇深Ｖ型和贺舭型在相同主尺度情况下进行了对比研究．根据模型阻力试验结果知，深Ｖ型的静水阻力与圆舭型相比，其增加值均小于７％．特别是随着航速增大，两者的阻力差值趋减小．在规则波中迎浪情况下的耐波性试验表明，两种艇型的横摇、纵摇、垂向加速度和失速均有明显的差别．高速排水型艇如果采用深Ｖ型，可望获得良好的耐波性．

The Comparison of Resistance and Seakeeping between Deep-Vee and Round Bilge Hull Forms

A comparative study between deep-Vee and round bilge hull forms for high speed displacement vessels under the same particulars is made. Based on the results of model resistance tests,the resistance of deep-Vee hull form in calm water has increased by 7% or less compared with one of round bilge hull form for the same displacement. Specially,the resistance difference between two hull forms will be reduced as the speed increased. The seakeeping tests in regular head seas show that there is a great difference between deep-Vee and round bilge hull forms,in the term of roll,pitch,vertical acceleration and speed loss. The better seakeeping qualities may be expected,if deep-Vee hull form is adopted for high speed displacement vessels.
