尾板宽度对高速排水型艇的阻力和耐波性影响

The Influence of Transom Breadth on Resistance and Seakeeping Qualities for High Speed Displacement Vessels

不同尾板宽度的两种艇型的阻力和耐波性试验结果表明：高速排水型艇的尾板相对宽度ＢＴ／Ｂｘ对阻力和耐波性均有影响，ＢＴ／Ｂｘ值过小的艇，其剩余阻力系数明显增加．ＢＴ／Ｂｘ作为影响高速排水型艇航行性能的船型参数较之尾板相对面积ＡＴ／Ａｘ更恰当．综合阻力和耐波性试验结果，ＢＴ／Ｂｘ值取等于或略大于０．７５是适宜的．

Based on the test of two groups of model with different transom breadth, the influence of relative transom breadth B T/ B x on resistance and seakeeping qualities are discussed. It is shown that residuary resistance coefficient obviously increases when transom breadth is too small. As the hull parameter affecting motion performance the B T/ B x is more suitable than relative transom area A T/ A x for high speed displacement vessels. Summing up the resistance and seakeeping test results, it is suggested that the B T/ B x is equal to or slightly greater than 0.75.
