【摘要】 在零、低航速和中、高航速工作模式下升力产生的机理相异,因此减摇鳍在两种模式下应用时对鳍型的要求不同,一些主要设计参数相互矛盾,造成全航速应用的减摇鳍鳍型设计和面积选择较为困难。通过分析鳍轴位置、展弦比、翼梢形状对零、低,中、高航速工作模式下鳍上综合水动力的影响,提出合理的鳍型参数和面积需求。为解决零、低航速下升力较小对鳍面积需求过大的矛盾,对鳍的变形技术进行研究,并对主要的变形技术进行了试验验证。给出了适合全航速应用的鳍型参数。更多还原

【Abstract】 There are different lift force generation mechanisms of fin stabilizer employed by zero-low speed working mode and middle-high speed working mode,which results in the different requirements for fin-type.Some of the major design parameters are conflicting,leading to the design and area selection of all speed fin stabilizer more difficult.A series of reasonable aerofoil parameters and fin areas are given with the analysis of the effect of shaft position,aspect ratio and wingtip on hydrodynamic force.Transmutation technique of fin is performed to resolve the conflicts of excess fin size demand at zero-low speed,while experiments about main transmutation technique are carried out to verify theoretical analysis.Optimal fin aerofoil parameters of fin stabilizer at whole speed range are provided and served as theoretical basis for engineering design.更多还原
