OPTIMIZATION OF PROPULSION SPEEDS

A computer design method for calculating fixed pitched propellers for a given ship. The propeller calculation uses Lerbs 11-Point Induction Factor Method, optimum geometry for given cavitation numbers, and strength analysis for blade sections. Optimization calculations produce the highest efficiency propeller for the ship specifications and produce the lowest fuel consumption propeller to satisfy combined specifications of engine, gear, and ship.
