Marine straight-wing propeller

The straight-wing propulsion is an old marine propulsion technology. Traditional straight-wing propellers frequently use the connecting rod configuration to control the blade swing which has excellent maneuverability. However, traditional straight-wing propellers have a high cost while a low propulsion efficiency. Nowadays only a few special-purpose vessels are selected for such application.

The straight-wing rudder propeller adopts the planetary gear transmission mechanism to control the blade movement. While having excellent maneuverability, the blade can also achieve a high-efficient hydrodynamic performance.

The straight-wing rudder propeller reinvents the traditional propeller propulsion method, and provides a better propulsion technology for ships.

☞ Large thrust area, shallow draft, high propulsion efficiency;

☞ Excellent maneuverability, accurate positioning and control of the ship;

☞ Smooth operation, small vibration, low noise;

☞ Excellent cavitation performance at high speeds, high hydrodynamic efficiency;

☞ High integration of the propulsion system，better use of the ship space；

☞ Hassel-free installation, maintenance and repair.
