针对进江船型操纵性要求较高而半悬挂舵升力性能较低的问题,基于CFD方法,采用翼型优化设计、制流板优化设计、随边直尾化设计3种技术措施对一型“曼谷型”集装箱船的半悬挂舵进行升力性能优化。对比升力系数和阻力系数计算结果;考察舵面流动和端部流动,分析增升原因;结合阻力因素考虑,确定实船应用的优化舵系方案。结果表明:3种技术措施均可有效提高半悬挂舵的升力性能。通过对比原船型和目标船型的操纵性试验结果,验证了实船应用的优化舵系对于改善目标船型操纵性的作用。
Aiming at the high requirement of manoeuvrability while low lift performance of semi-spade rudder on the river-entering vessels, based on CFD method, applying three kind of technical measures including rudder profile optimization design, swash plates optimization design and flat tail design of trailing edge on the semi-spade rudder of a “Bangkok type” container vessel for enhancing rudder lifting performance, compare the results of lift coefficient and drag coefficient. Study the surface flow and ends flow of the rudder, analyze the causation of lift performance rise. Consider with the drag factor, determine the optimized rudder solution for the actual vessel. The results show the three kind of technical measures can effectively enhance the lift performance of semi-spade rudder. Comparison of the manoeuvrability test results between original vessel and object vessel verifies the effect of the optimized rudder solution for improving the manoeuvrability to the object vessel.
