摘要
喷水推进是一种船舶推进方式,喷水推进器依靠进流与出流的动量差产生推力,会对船体周围的流动产生显著影响。基于裸船体计算得到的操纵性水动力系数与喷水推进器工作状态下得到的预报之间存在差异,这将影响船舶操纵性的预报。研究项目利用平面运动机构(PMM),分别开展带喷水推进装置的船舶操纵性水动力系数模型试验和相同工况下的裸船体试验,对比各项操纵性水动力系数的变化情况,总结出喷水推进装置对船舶航行稳定性的影响,找到关键的影响因素,为深入探究喷水推进器进出流动对船舶操纵性能的影响打好基础。
There is momentum difference between the inflow and outflow of waterjet propulsion,so that surrounding flow of the hull will be disturbed,and maneuverability will be influenced.In this study,model tests of a ship with and without waterjet propulsor are carried out with the help of planar motion mechanism(PMM).Measured maneuvering coefficients of the ship in both cases are compared,and key factors influencing the maneuvering coefficients are discussed.
