摘要
螺旋桨设计是船舶设计中重要的组成部分之一.基于船舶设计NAPA软件平台,使用NAPA自带的NAPA BASIC语言,利用坐标变换方法,根据螺旋桨桨叶的伸张轮廓和叶切面形状,得到了桨叶几何造型所需的三维坐标值,同时研究了桨叶二维图形的生成方法,从而有效地将船舶设计软件与螺旋桨的几何造型紧密结合起来,节省了大量的人力物力,提高了工作效率,推动了计算机技术在螺旋桨设计领域的应用,为船用螺旋桨的精确和高效绘图寻求了一条新途径.
Propeller design is one of the most important part of ship design. Based on NAPA-software of ship design, three-dimension coordinate value was obtained by using NAPA BASIC language and coordinate transform. Simultaneously, two-dimension figure of blade was created with the help of promoting outline and section shape of blades. Sequentially, the method is effective to link geometrical body of blade with software of ship design. Also, it may need little manpower material resources. Furthermore, it can improve the application on computebased propeller design, and find a new way to plot exactly and effectively.
