Abstract:

The previous analysis of the propeller-rudder interaction problem by means of the lifting surface theory has been modified to include the effects of thickness of both surfaces. The effect of thickness on the flow displacement in the field is taken into account by the thin body approach. The blade thickness effect on the loading of the propeller blade due to its non-planar form, being small, is neglected. The resulting field are incorporated, together with the onset velocities due to hull wake and camber and incident angle of the surfaces, into the existing iterative procedure. The numerical procedure, adapted to the CDC-6600 high-speed digital computer, furnishes the steady and time-dependent pressure distributions on both lifting surfaces and the resulting hydrodynamic forces and moments.
