| 摘 要： | 以船体、导管和前置定子及转子组成的系统的推力减额特性为研究对象,基于因子分析理论,提出了该三因子系统的水动力相互干扰分析模型,导出了诸因子之间相互影响的求解公式,并采用分解试验方法实现了所有效应的准确测定.分析研究了系统推力减额的两种不同处理方式,建立了相应的评价指标体系.通过对两个特定方案的评估分析,推荐采用k2和t2作为系统推力减额性能优劣的综合评价指标,并建议采取以减小RrlH和RrlSD为主要方向的优化策略.

| Abstract: | The focus of this investigation is analysis of the thrust deduction characteristics of submerged hull/duct stator/rotor system.On the basis of factor analysis theory,a hydrodynamic interference analytical model for this 3-factor system was developed and the calculation equations about the interactions among different factors were derived.Through de-compound experimental method,the interactions were accurately measured.Two different solution methods for thrust deduction fraction were studied and the relevant assessment indices were found out.Through case studies of two specific examples,k2 and t1 are recommended as the comprehensive assessment indices of the thrust deduction properties for this system and reducing Rr/H and RR/SD are suggested as the main direction for further optimization. |
