How do our CFD-designed, fully CNC-machined propellers save you money and reduce time out of the water? By designing them to minimise cavitation, our propellers have an extended working life (and extended replacement cycle), as testified by this recent positive feedback we received from Brian Nielsen, Technical Superintendent at DanPilot:
“It’s interesting to notice we never had cavitation issues on the propeller hubs on the 17 boats (34 props) we have equipped with CJR propellers. Several of the boats has now 30,000 hours use.”
How do we do it? Cavitation is the erosion of the surface of the propellers and rudder. Our experience using CFD analysis means we can predict and minimise cavitation by understanding the flow of water around the propeller and making adjustments to the design to reduce the pressure pulses that cause the issue.
Our CFD-designed, fully CNC-machined propellers also:
– Significantly improve propulsive efficiency due to bespoke nature and optimised rake and skew – reducing engine load by up to 3% at the same RPM to reduce fuel burn by up to 10%, or increase top speed by up to two knots
– Reduce vibration by up to 50% compared to standard pattern props for improved ride comfort
– Are designed using advanced computational fluid dynamics for each individual vessel, whilst considering expected use, location and owner’s performance preferences
– Are manufactured using pattern-less mould-making and five-axis CNC machining for total adherence to the CAD design
– Can be manufactured to any classification society rules, including all IACS societies
These pilot boats are working hard and we’re delighted our customer is seeing such positive benefits of fitting CJR Propulsion propellers to their fleet.
