The Use of Cyclone Impeller Technology to Improve Thrust Efficiency and Reduce Operational Costs in Marine Propulsion

This study explores the design and application of an innovative cyclone impeller aimed at improving thrust generation while significantly reducing energy consumption and acoustic disturbance in marine propulsion. Laboratory tests demonstrate an 88.8% increase in thrust compared to conventional propellers, which translates into a projected energy saving of over 50% when operating at constant speed. The impeller’s vortex-inducing geometry suppresses cavitation, lowers mechanical stress, and enhances operational silence—making it particularly advantageous in both commercial and military maritime sectors. These findings offer meaningful implications for cost reduction and environmental sustainability in fluid-driven systems.
