High efficient design software is increasingly important to the development of propeller as much progress has been made in the ship industry. The propeller design software integrated with prediction of hydrodynamic performance was developed in the Visual Basic 6.0, coupled with the Fortran and dynamic link library technology. This user-friendly software use lifting line method to realize propeller design and optimization, and then by lifting surface method to predict hydrodynamic performance. The experiment results proof that the software provides benefits in the following: complete functions and high level of visual effect and good usability in rapid and accurate predictions and design.%随着船舶行业的不断发展,迫切需要一种设计软件来提高螺旋桨的设计效率.基于Visual Basic6.0开发平台,结合Fortran和动态链接库技术,实现了螺旋桨设计及水动力性能预报软件的设计.软件运用升力线理论完成了螺旋桨的设计与优化,进而运用升力而理论对螺旋桨的件能进行了预报.该软件界面友好、功能完善、可视性强,试验结果证明,能快速准确地进行螺旋桨设计及性能预报,提高了螺旋桨的设计效率,具有良好的使用性.
