舵型参数对襟翼舵升力特性影响的数值计算研究

摘要

论文通过对中国船舶科学研究中心开发的船用襟翼舵(CSSRC舵)计及尾翼缝隙位置的敞水升力特性进行数值模拟研究,分析了舵型参数对襟翼舵升力特性的影响规律;在此基础上,以在CSSRC舵上增加整流尾的方式,设计出了鱼尾型襟翼舵,并通过数值计算比较该鱼尾型襟翼舵与CSSRC舵以及NACA66剖面襟翼舵的升力特性,显示其具有更高的升力性能;最后根据系列计算结果,运用逐步回归方法对三种剖面翼型襟翼舵给出了具有工程实用价值的升力系数计算公式.%In this paper,hydrodynamic characteristics of the CSSRC flap rudder are studied and simulated with consideration of the influence of the tail wing gap.By adding a contra tail to the CSSRC rudder,the fish-tail type of flap rudder is designed and its lift performance is compared with the CSSRC rudder and the one with NACA66 profile respectively in the same condition.Numerical results demonstrate that the fish-tail type of flap rudder has better performance.Comparatively accurate regression formulae of the hydrodynamic performance for the three rudders are put forward with the stepwise regression method.
