Optimization Of A Military Ship Propeller To Minimize Fuel Consumption

The optimization of propeller has always been one of the most important aspects of propeller design. Reducing fuel consumption is also an important aspect of ship and propulsion system design to reduce the costs. The proposed design methodology represents a new approach to evaluate the propeller design of a military by considering the various missions. So three different modes propulsion system, e.g. Trial, Half and Full modes in which, respectively, one, two and four propulsion motors are used will be considered. Also the propeller using genetic algorithm is optimized by considering the fuel consumption along with system performance characteristics and constraints such as trust, torque, stress, cavitation, efficiency and skew angle to the best forward speed with minimum fuel consumption is resulted.
