摘 要二十一世纪以来，能源危机和环境污染问题日益严重，探求跟多的绿色环保节能资源成为了新世纪的重大主题，用新能源代替化石燃料能源，在持续发展的大背景之下风能逐渐进入人们的视野， 从而现代化风帆助推船和更高效率更加环保的绿色船舶研发越来越引起人们的关注。 本文设计了一种平凸翼型风帆并对其风帆进行研究。本文首先根据现有的风帆的运作原理筛选出适合的风帆类型， 在机翼理论的基础上进行计算，选择合适的翼型参数，开展模型实验，更加直观地证明设计的翼型帆有利于船舶的推进并估算其推进效率， 同时设计基于四万吨散货船的风帆助推船，对于风帆的尺度以及参数进一步的确定。接着在风帆助推船的基础上， 利用风帆的具体参数和船舶本身的主尺度根据国内外风帆助推船稳性校核规范运用maxsurf 软件对于该船进行稳性校核， 在此基础上运用FLUENT、Profili 软件对设计风帆的推进效率进行进一步推算。62271

Abstract The 21st century, energy crisis and environmental pollution problem isincreasingly serious, to explore with more green environmental protection and energysaving resources has become a major theme in the new century, new energy instead offossil fuel energy, under the big background of sustainable development of windpower gradually into people's horizons, to modern booster ship sails and higherefficiency more research and development of environmental protection of green shipis more and more aroused people's concern. In this paper, we design a flat convexairfoil sail and to study its sails.At first, this paper based on the principle of the existing operation of the sail outfor sail type, on the basis of the airfoil theory to calculate, choose the appropriateprofile parameters, experiment more intuitive proof design of airfoils sail for shippropulsion, at the same time, design based on the forty thousand tons of bulkcarrier booster ship sails, and further to determine the parameters of the scale of thesail.Then on the basis of the booster ship sails, specific parameters and using sails ofthe ship itself principal dimensions according to the domestic and foreign sail boostership stability checking specification using maxsurf software stability checking for theship, on the basis of using the FLUENT software, Profili software to design the sailspropulsive efficiency for further calculation.
Keywords: sail-assisted propulsion; booster;airfoil profile parameter ;stabilitychecking propulsive efficiency
