摘要
本文叙述了敞水螺旋桨在规则波中有纵摇升沉运动情况下进行的模型试验,得到了在一定航速和不同波浪频率时螺旋桨推力和转矩随进速系数变化的性征曲线,给出了它们之间的关系式,可供初步估算。试验结果表明螺旋桨在波浪中的推力和转矩值均大于静水值。本文还利用三维 Green 函数法,以汇盘代替螺旋桨计算了桨在规则波中运动时的敞水水动力性能,并与模型试验比较,结果吻合良好。最后,计算了桨轴浸深对波浪中敞水桨推力和转矩的影响。
The paper describes the open water tests of propeller model withpitching and heaving in regular waves.The characteristic curves of th-rust and torque of a propeller moving at given speeds and under avari-ety of wave frequencies are obtained.The relationship between those inwaves and in calm water are established which can be used for preli-minary estimation.The open water propeller hydrodynamic performancein regular waves are also calculatd by using 3-D Green function methodin which the propeller was replaced by sink disk.The calculation resu-lts are in accordance with tests.In addition,the effects of the imme-rsion of propeller axis on the propeller performance are also calculated.
