Fixed pitch propellers
NHV effect
NHV Type
Conventional Type
Because of Nakashima’s unique technology, hub vortex causing energy loss and rudder erosion can be reduced by using specially shaped propeller blades, without the use of any special accessories. Reduced hub vortex improves efficiency and prevents rudder erosion.
Tip Rake effect
Tip Rake Type
Conventional Type
The unique shape of the blade tip developed by Nakashima is expected to reduce cavitation and aft fluctuating pressure.
High skew effect
Propellers with a sharp sweepback are called “high skew” propellers. Their unique shape reduces the vibration of a vessel's body as well as propeller noise.
Keyless propellers
With keyless propellers, no key is used to connect the rotating shaft and propeller. When the propeller shaft is press fit into the shaft hole of the propeller, the contact part becomes completely joined under specific conditions. Once the shaft and propeller are joined, the propeller is completely attached without being pressed back from the shaft. Since keyless systems are extremely reliable, most large-size merchant vessels use keyless propellers.
