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
