The fundamental basis for a rudder design methodology as a computational tool for deriving forces and moments on a ship rudder is described. Rudder performance for a wide range of rudder geometries and positions downstream of a propeller or in the free-stream can be determined. The software uses the fundamental physical processes which control rudder and propeller interaction coupled with a large set of wind tunnel test data to produce accurate and workable results for design. Rather than curve fitting, the correction algorithm applies a change to the force on the rudder to the nearest known set of data. This ensures that the software experimental database is utilised fully. The rapid prediction of rudder forces, be they for manoeuvring force prediction or rudder design strength calculation, allows the designer to consider the effect on rudder performance of the principal design constraints.
