As global concerns over climate change grow, the shipping industry is facing increasing pressure to reduce carbon emissions. Although crucial for global trade, shipping contributes to approximately 3% of global greenhouse gas emissions. In response, the International Maritime Organization(IMO) established a "Net Zero" goal by 2050, intensifying the demand for eco-friendly shipping technologies. Among these, the rotor sail, which utilizes the Magnus effect to provide auxiliary thrust, has recently received significant attention. In this study, the aerodynamic performance of rotor sails with various design configurations is mainly discussed based on numerical simulations. Eight different rotor sail designs including telescopic model, convex and concave shapes were newly suggested from the base model of rotor sail. In this study, various performance parameters such as lift, drag, torque and energy efficiency were compared and discussed. Additionally, the drag of various geometries in the stationary state were also analyzed.
