Core parts and design capabilities of the contra-rotating propellers
Mar 08, 2019

The contra-rotating propellers requires the structural advantages of the contra-rotating propeller and the maneuverability of the full-rotation rudder propeller during operation. It can effectively reduce the propeller diameter, improve propulsion efficiency, and reduce vibration and noise while providing full-throw thrust. It is mainly used for ships with special requirements or special restrictions, such as transport ships, car ferries, oil spill recovery vessels, and sanitation engineering vessels.

 

The full-rotation rotary propeller is mainly based on its imported core parts and design capabilities, and can provide high-quality high-power propellers for our customers. Nickel-aluminum bronze 4 leaves on the paddle. Control system Siemens, the full set of control uses real-time dual system online backup to ensure the reliability of the control system.

 

The full-turn contra-rotating propeller is a Z-type propulsion device that integrates the counter-rotating propeller and the steering gear. The underwater part can be steered by 360-degree free rotation to form an all-round thrust. The device combines the structural advantages of the contra-rotating propeller with the flexible features of the 360-degree steering gear, which can effectively reduce the diameter of the propeller, improve the propulsion efficiency, and reduce vibration and noise. It is mainly used for ships with special requirements or special restrictions, such as transport vessels, car ferries, oil recovery vessels, and sanitation engineering vessels.
