螺旋桨绘图数值计算程序

A calculation program for the mapping data of ship propeller

螺旋桨设计完成后，绘图时要进行许多计算，并且要用作日方法求出各相对半径处随边和导边的长度才能作图。本程序通过计算机，根据需要可计算出B型、JB（经验）型、MAU及AU型、Ka型四种桨中的任何一种桨的伸张轮廓、展开轮廓和投影轮廓的x、y、z三个坐标，并可计算出各相对半径处叶剖面各部位的厚度。在计算机上仅需几分钟即可打印出所需数据。

The x, y, z coordinates for mapping the expanded,the developed and the projected contour,as well as the thickness at various rela tive radii of the blade of a designed propeller with B, JB, MAU or AU. and Ka type can be calculated by this program. As the specified data are keyin.after a few minutes.the output of the aforesaid deta will be completety printed out.
