Case study shows that remarkable increase in the thrust deduction efficiency could be achieved by optimizing the arrangement of the after-body parameters L, C and propulsor parameterA/A.
Through case studies of two specific examples, k2 and t2 are recommended as the comprehensive assessment indices of the thrust deduction properties for this system and reducing R(subscript r/H) and R(subscript r/SD) are suggested as the main direction for further optimization.
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.
