Influences of Pod on the Propeller Performance.

Based on the theoretical prediction method and experimental results for single-propeller type podded propulsors, the influences of the pod upon the propeller hydrodynamic performance were investigated. The propeller blades are calculated with a vortex lattice method, while the pod including its strut with a boundary element method for non-lifting bodies. Hydrodynamic interactions between the propeller and the pod are treated via iterative calculations. Based on the present numerical results, the influence of the pod on the radial distribution of circulation as well as the pod-induced wake characteristics were discussed. [ABSTRACT FROM AUTHOR]
