DESIGN AND SIMULATION OF A CONTROLLABLE PITCH MARINE PROPELLER FOR ENHANCED MANEUVERABILITY AND EFFICIENCY

ABSTRACT

The project is focused on designing and simulating a controllable-pitch marine propeller for small to medium sized vessel such as fishing trawlers, passenger ferries, tugs andyacht, recognizing the pivotal role such technology plays in optimizing vessel performance. By addressing limitations in conventional fixed-pitch propellers, theproject has been able to contribute to the evolution of marine propulsion systems, pushing the boundaries of efficiency and adaptability. The project methodology involved a comprehensive literature reviewon marinepropulsion and propeller design principles, followed by the formulation of amathematical analysis for the controllable-pitch propeller design. SolidWorks 3Dmodeling software is utilized to create a detailed propeller design, which is thensubjected to Computational Fluid Dynamics (CFD) simulations to analyzehydrodynamic performance. An iterative optimization process refines the design basedon simulation outcomes, aiming for enhanced efficiency and performance. Through parametric studies and optimization, the project successfully demonstrates theefficiency gains achievable by adjusting the blade tip pitch angle. The controllable-pitchpropeller's ability to adapt to varying operational conditions is highlighted, showcasingits potential for improved fuel efficiency and maneuverability. The project contributes tothe ongoing advancements in marine propulsion technology, offering insights intothedesign and simulation of controllable-pitch propellers for small to medium-sized vessels
