摘　　要：为改善船舶推进和海洋工程建筑物动力定位的性能,作者已经完成了JDC—3叶可调螺距螺旋桨系列及JDC—3叶导管调距桨系列的试验研究,本文将给出一组JDC—4叶可调螺距螺旋桨系列的试验结果。 该组桨的盘面比为0.55,敞水试验结果按初始螺距比、进速系数以及初始螺距比、转角、进速系数二种组合参数进行回归分析。给出了敞水性征曲线及对应的回归多项式。同时,给出了(B_P)^(1/2)—δ图谱供设计使用。A four-blade controllable pitch propeller series with expanded area ratio of 0.55 has been developed for improving motion behaviour of the ship and ocean engineering. The experimental results of the series are presented heve.The fairing of the open water test results has been performed by means of a regression analysis.The regressive coefficients.open water characteristics curve and Bp-δ diagrams for the expanded area ratio are also given in the paper.
