摘要
针对一艘支线型集装箱船,基于模型试验,研究导边扭曲舵、随边扭曲舵及舵球对船体推进功率的影响。对扭曲舵的导边和随边扭曲角度和舵球的形式进行了系列试验。研究结果表明:随着导边扭曲角度从4.0°增大到6.0°,在包含设计速度的一定范围内,船体推进功率降低。随边扭曲对船体推进功率影响不大。安装椭圆流线型舵球形式的扭曲舵的船体快速性能优于安装大平头型舵球扭曲舵船体的快速性能,在实船应用中效果较好。
In the paper,based on a container vessel the influence of rudders with twisted leading edge and/or trailing edge as well as bulb has been examined with the use of model tests on the delivery power at design draught of subject vessel.The obtained results indicate when the twisted angle of leading edge increases from 4.0 to 6.0 degree,the delivery power would decrease.Another is gotten there is no big effect on the delivery power with rudders with different twisted trailing edge.Finally,we find the rudder bulb with ellipse section has a good speed performance,especially used in the sailing ship.
