摘要
本文从船舶安装风帆后的受力分析出发,建立了风帆助航节能计算的数学模型。结合我国沿海各主要航线所经海域的全年风向风力资源统计资料,以及现代矩形层流硬帆的试验数据,编制了计算机程序,得到航线上各统计区海域每平方米风帆面积所能获得的功率增益,从而可以了解中国沿海风帆助航节能的潜力。本文也可作为风帆助航船初步设计时,确定风帆主尺度的依据。
Based on the analysis of the forces acting on a sail-assisted motorship, the mathematical models for estimating the energy-saving effect on ship propulsion is established. According to the statistical data of wind force and direction along the coastal waters of China, by using the aerodynamic characteristics of rectangular rigid sails under laminar flow obtained from tests in wind-tunnel, the power gain of sail area per square meter for ships along the service route may be calculated with the aid of computer program. The energy-saving potential is worthwhile to be considered. The dimensions of auxiliary sails to be set up on board motorship may be determined in the preliminary design stage.
