AN OPTIMISATION PROCEDURE FOR PROPELLER SELECTION FOR DIFFERENT SHAFT INCLINATIONS

In this paper, a propeller optimization model is presented to find the optimum geometry and gearbox ratio for different angles of shaft while minimizing amount fuel consumed at given speed complying with proposed constraints' limitations. The developed couples several simulation software where application programming interface (API) facilitates data processing achieve design based on procedures. A fishing vessel selected as case study perform numerical simulation. comparison conducted between optimized propellers inclination among blades. Bar chart box whisker plot are two techniques considered visualize computed data. results conclude that high number blades small angle (2 degrees) can operate engine operating point in horizontal shaft, which most efficient from theoretical view.
