To meet the harsh ocean environment, NGC engineers take full
consideration of reliabilities during the hydrodynamic calculation,
structural design and material selection, which make our
controllable pitch propellers are featured with good reliability,
simple configuration and maintenance friendly, etc. The hub is
designed with large diameter servo piston, and the hydraulic force
of the piston works on the yoke, so as to decrease the work oil
pressure required by the hydraulic system.
Combining the test to the propeller design, we apply the large skew
propeller and optimal disc ratio solutions to lower down the
cavitations and vibration of the propeller, in this way, not only
the navigation speed and towing force can be satisfied, but also
the operation performance and economical efficiency of the ship is
improved.
During the shaft line design, the engineers take account of the
negative influence to the shaft strength, vibration and alignment
caused by the bending stress load change, propeller stress, gear
meshing load and the bending stress of main engine crank shaft, and
the calculation result fits more with real work condition.
During the navigation, if the feathering CPP does not work, the
blades can be adjusted to the downstream condition to decrease the
resistance effectively.
