【摘要】 本文是在BP＾2-δ设计图谱多项式表达的基础上编制的螺旋桨图谱设计计算机程序，能适用于各种类型的螺旋桨系列，参数按表型数据文件填入，简单明了，可按不同要求进行初步设计和终结设计，速度快，结果精确，并可对一已知桨进行性能预报。是船厂和设计部门实用的计算机软件，有着良好的推广和应用前景。更多还原

【Abstract】 A computer-aided propeller design and performance prediction method is presented with polynomial formulation based on ■-δ chart. A general computer code with simple input is developed. According to the differentrequirements, the propellers preliminary and final design could be completed with accurate computational results invery short time. The developed computer software, suitable for various propeller series, may provide a practicaltool to shipyards and design departments.更多还原
