【摘要】 为改善船舶推进和海洋工程动力定位的性能,对导管螺旋桨及可调螺距螺旋桨进行了多方面的研究工作。采用导管可调螺距螺旋桨可兼顾二者之优点进一步改善其推进性能。 利用交通大学JDC三叶可调螺距螺旋桨系列和JD7704导管组合成导管调距桨系列,本文提出了全部试验及分析结果。 用多元回归分析方法对全部试验结果进行处理。最后,给出了回归系数,敞水性征曲线,水动力及离心力转叶力矩值以及（B_p）^1/2-δ图谱,供设计使用。更多还原

【Abstract】 The series of ducted three blade controllable pitch propellers is made up of JDC three blade controllable pitch propeller series and simplified duct JD 7704 developed by Ship Hydrodynamics Laboratory of the Shangha’ Jiaotong University.All experimental results are presented here.The fairing of all experimental results has been performed by means of a regression analysis.The regressive coefficients, open water curves, hydrodynamic and centrifugal blade spindlle torque curves, and diagrams are also given in the paper.更多还原
