摘要
本文以某型1500 t级散货船为目标船,选用翼型硬帆及其风力助航系统,并分析其空气动力性能。通过理论研究其最佳帆位角与表观风向角的关系、升力系数和阻力系数随攻角的变化关系等;并在理论研究基础上,进行小型风帆模型船模拟试验。证实了该目标船设计的可行性和合理性,为翼型帆船的设计提供理论参考。
The aerodynamic characteristics of wingsail-assisted navigation system of the 1500 t river bulk carrier is analyzed in this paper.Based on the theoretical study of the relationship between the best sail angle and the apparent wind direction angle,the relationship between the lift coefficient and the resistance coefficient along with the change of angle of attack,the simulation experiment of the small-scale sail model ship is carried out.The change rule of the best angle of attack and the best control curve of the wingsail are obtained,which provides a theoretical reference for the design of sail control system.
