Contra-Rotating Marine Propeller
This counter-rotating propeller's design achieves a 10%-15% higher efficiency compared to conventional single propellers. It maintains an average working time between failures of greater than 5000 hours.





Technical Specifications
Overview
Advanced Marine Propulsion
This contra-rotating marine propeller system utilizes two propellers rotating in opposite directions on a common axis to significantly enhance propulsion efficiency. By avoiding the high-speed mutual rotation of inner and outer shaft sleeves, the design reduces bearing heating and improves operational safety. The streamlined, compact gearbox minimizes water flow pressure, resulting in a system that is 10-15% more efficient than conventional single-propeller configurations.
