1, fixed pitch propeller for large vessels
1-a, PAI propeller
High propeller efficiency
Stable propeller characteristics obtained at conventional model test facilities
Theoretical calculations match actual performance characteristics
1-b, CONTRA-ROTATING PROPELLERS
The photo below shows a Contra-rotating propeller based on the IHI Marine United design. Contra-rotating propellers are more efficient than conventional single propellers as they eliminate power losses due to rotational flow
2,Fixed Pitch Propeller for coastal,special vessels
Using cutting edge technology, Nakashima is able to design the optimal propeller, efficient at all operating conditions for ferries, fishing boats, tug boats and other medium sized vessels.
