Based on the systematical investigations on interactions of propeller and rudder, a theoreticalprocedure for unsteady performance of the propeller and rudder system is proposed. An unsteady vortexlattice method and a potential based panel method are applied for predicting the unsteady performances ofthe propeller and the rudder behind the propeller respectively. In this procedure the iteration is needed untilthe periodical variation of thrust and torque coefficients of the propeller converges. Several examples areperformed. Comparisons between the calculated results and the experimental data indicate that the presentmethod is reliable, and maybe put into application.
