摘要
毂帽鳍设计方案大多依靠模型试验优选确定,且只是对螺旋桨进行毂帽鳍匹配设计,没有充分考虑桨鳍间影响。本文拟将螺旋桨与毂帽鳍作为一个整体进行一体化设计,并在设计过程中融入桨叶根部加载反常规设计思想。叶根部加载,可均匀螺旋桨径向载荷,减小螺旋桨激励力,并利于抑制梢涡产生;叶根厚度大、强度大,不易被激振,负荷内移有利于降噪;产生毂涡是叶根加载的副作用,恰好可用毂帽鳍来消除毂涡,并提供附加推力。因此,本文提出的设计方法有望得到综合性能更优的螺旋桨毂帽鳍推进系统。本文通过势流理论、粘性CFD技术和改进的粒子群优化算法及模型敞水试验来进行设计方法的研究,得到理论设计与数值优化设计相融合的螺旋桨与毂帽鳍一体化设计方法。设计方案的模型试验结果表明,本文设计的螺旋桨与毂帽鳍具有更高的整体推进效率;本文的设计方法是有效、可靠、实用的。
