Contra-rotating propeller rudder propeller: The design power is 40kW~5MW, and the installed power is 40kW~1.7MW. It is suitable for various speed comparisons such as car-passenger ferries, passenger/cruise ships, engineering ships, and official ships, high sped ship etc. The rudder propeller transmission mode can be Z-type or L-type; the rotation mode can be hydraulic or pure power.
From 2013 to 2017, we provided 17 sets (34 units) of 1.4MW ( 1900hp) contra-rotating propeller rudders for the xx ships of the army. The actual ship achieved a performance beyond the original conventional. The 0.5kn index requirement of the thruster plan and the overall performance index meet the requirements at one time.
Nozzle type rudder propeller: The design power is 100kW~4.5MW, and the installed power is 100kW~2.2MW. It is used for tugboats, marine engineering and other types of ships with relatively high towing power requirements return. The rotation mode can be hydraulic or purely powered.
