摘要
基于大升力翼型风帆,完成风翼模型的风洞试验,并根据试验结果对该风翼空气动力参数进行了分析。计算和比较不同航速时,风翼辅助推力随绝对风场风向和风速的变化规律。根据船舶试航和营运数据设定各航速下的风翼辅助推力下限值,得出风场的可用区域。最后进行数学建模,提出了使用数学方程描述和求解风场的可用区域的方法。
A wind tunnel experiment was carried out for a wing-sail that had great lift force, and its aerodynamic parameters were analyzed. The law of wind propulsion force varying with absolute wind direction and speed was calculated and compared at different ship speeds. According to the data of ship trial and service, the lower limit of wind propulsion force was set under different ship speeds, thus applicable range of the wind field was figured out. At last,a mathematic model was established and a method with mathematical equations was proposed to describe and solve the applicable range.
