【摘要】 略减后体方形系数,尤其在肥大船对阻力、推进和伴流分布会带来有益的影响,又从节能角度而言,肥大船加装球鼻首在国内外已获得广泛的应用。故略减后体方形系数并加装球鼻首可在排水量基本不变,以满足合同中要求的载重量的条件下使阻力和推进性能有明显改善。通过船模试验证实上述设想的实效性,是一种改进肥大船线型设计行之有效的途径,因而具有一定的实用参考价值。更多还原

【Abstract】 Slightly reduced afterbody block coefficient will bring about beneficial effectson the resistance,propulsion and wake distribution of ships,especially for large fullships.Attached bulbous bow to large full ships has wide application in our countryand abroad to save energy.So slightly reduced afterbody block coefficient addedwith a bulbous bow can appreciably improve the resistance and propulsive qualitiesunder the condition of nearly constant displacement which is required for thedefinite deadweight as specified in certain contracts.The effectiveness of the aboveassumption has been confirmed on the basis of ship model experiments.It is aneffective means to improve the design of hull lines of large full ships.更多还原
