A wide range of hub sizes is available for powers from around 500kW up to 75MW for both four and five bladed propellers. The Kamewa 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 propeller is also available as full feathering.
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
