| Abstract: | In this paper the quasi-steady lifting line method is used to calculate the dynamic characteristics of propeller operating in the non-uniform wake of the ship hull, taking into account both the viscous and the three dimensional effects. A method based on constructing an equivalent two-dimensional hydrofoil for the blade section is suggested to estimate the pressure distribution along the chord. The calculation results of propeller characteristics and pressure distribution along the section chord show good ageement with experiments. The computer program for above mentioned purpose can be provided to the primary ship design. |
