高速船减阻减摇艏艉鳍的试验研究

An experimental investigation on resistance reduction and motion control by the fins attached to the hull of speed ships

采用试验研究的办法 ,探讨了减阻减摇艏艉水鳍在傅氏数Fr =0 .5～ 0 .9的范围内圆舭快艇上应用的规律性问题 ,通过对某型舰艇模型的试验研究表明 :Fr =0 .5～ 0 .9的圆舭快艇模型总阻力可减小 5 %～15 % ,且在波浪中的适航性有明显的改善 .

An experimental method is introduced to investigate the regularity of resistance reduction and motion control by the bow and stern fins attached to the hull of high speed round bilge ships, the Froude number of which equals to 0.5～0.9. The model test of a naval boat shows the amount of the total resistance reduction by the fins reaches 5 % ～15 % for the round bilge model when its Froude number equals to 0.5～0.9, and the seakeeping performance of the model is improved distinctly.
