摘要
本文介绍了一种适用于 Froude 数 Fr=0.4～0.85,长度与排水体积比 L/(?)^(1/3)=5.5～8.5,阻力性能优良的中速艇艇型系列。阐述了该艇采用“宽尾、圆舭、短折角”线型的设计指导思想。根据系列模型阻力试验结果,绘制了可供初步设计阶段迅速而准确地估算实艇阻力的图谱。通过与国内外有关资料的比较,证明本系列艇在快速性和耐波性方面均有所提高。
A series of hull forms for medium-speed crafts of length-displace-ment ratio L/(?)^(1/3)=5.5～8.5,with good resistance characteristic withinthe range of Froude numbers Fr=0.4～0.85,is presented.The conceptof adopting a“broard transom,round bilge and short chine”hull formis also described.Based on the results of model test,diagrams for esti-mating full-scate craft resistance at preliminary design stage are derived.By comparing with the data at home and abroad,it is indicated thatthe adoption of hull form of this series will lead to reduction of resi-stance and improvement of seaworthiness.
