They can be delivered with 3, 4 or 5 blades. The propeller hub and blades are made in Ni.Al.-Bronze. They can also be delivered in Stainless steel. The hydrodynamic blade design calculations are based on detailed analysis in computers together with Finnøy’s long experience. The pitch is adjusted by a pull-push rod inside the hollow propeller shaft. It transfers the axial force from the servo piston mounted inside the gearbox. PROPELLER DESIGN All ships have individual needs. To satisfy these needs Finnøy use the most suitable software together with their experience when designing propeller blades. Propeller blades are designed for best possible performance regarding thrust, efficiency, noise, and vibration. The blades are machined and balanced according to ISO 484 standards. FEATHERING POSITION Feathering position is used to minimize the drag from the propeller when it is not in use. Typical vessels are sail ships and double ended ferries.
