船舶平行中体加长对快速性的影响

Effect of Parallel Middle Ship Body Length on Ship's Powering Performance

简介一艘中等方形系数船舶加长平行中体前、后船模快速性试验研究情况,分析了平行中体加长对该类型船舶阻力、推进性能的影响。试验结果表明,在一定范围内对这类船舶加长平行中体,阻力性能改善,推进性能在一定航速范围内略有提高。对于批量设计、生产船舶是一项经济、可靠的实用方法。

Powering performance test results of a medium block coefficient ship model with and without lengthening its parallel middle body are introduced.The effect of lengthening parallel middle body on ship resistance and propulsion performance is analyzed.The test results indicate that lengthening parallel middle ship body within a certain extent can improve(ship's) resistance and propulsion performance.
