Controllable pitch propeller
Offering a significant increase in efficiency and a blade foot with decreased exposure to cavitation. Our controllable pitch propellers are renowned for their high efficiency and blade bearing arrangement designed to avoid peak pressures and cavitation.
A wide range of hub sizes is available for powers from around 500kW up to 75MW for both four and five bladed propellers. The CP-A controllable pitch hub is an evolution of XF5 system, renowned for its high reliability and blade bearing arrangement designed to avoid peak pressures and cavitation. Compared to its predecessor, the CP-A offers a 20 per cent improved power-to-weight ratio, a significant increase in efficiency and a blade foot with decreased exposure to cavitation. Propellers can be supplied with four or five blades of high skew or moderate skew type, conventional or nozzle design. The propellers are also available as full feathering.
Oil distribution system
CP propellers are available with three types of oil control system, to match most vessel requirements.
- System D-F
- System D-M
- System I
The oil distribution box is mounted on the forward end of the reduction gearbox. Additional intermediate shafts can be arranged between the propeller shaft and the gearbox.
A separate shaft carries the oil distribution box, and additional intermediate shafts can be arranged between the propeller shaft and the OD box shaft.
Oil distribution integrated within the reduction gearbox, also part of our supply.
- Two main hub types are available: 'standard' for speeds below 30 knots and 'H' for speeds above 30 knots
- The CP-A hub offers normal pitch control and can be supplied with full blade feathering for reduced drag when not driving
- Bronze or stainless steel blades and hub can be specified
Open water, nozzle, and ice-class options
- Full US Mil-Spec shock versions are available
