CP Propeller

The CP Propellers are manufactured from 1000 mm to 5000 mm in diameter. They are delivered with 3, 4 or 5 blades. The propeller hub and blades are manufactured 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 propeller shaft is hollow bored and made of carbon steel or stainless steel. The pitch is adjusted by the push – pull rod. It transfers the axial force from the servo piston in the gearbox to the pitch setting mechanism in the propeller hub. The propeller hubs, type P26 to P48, are grease lubricated and from P39 to P125 are oil lubricated.

The stern tube is delivered complete with bearings, sealing boxes and a gravity tank for stern tube oil. The stern tube can be delivered suitable for either oil or water lubrication. The sealing boxes are Finnøy’s own design, but other types can also be supplied. The propeller shaft flange is a split type for the smaller shafts and an oil shrink type for the larger shafts.

Benefits of controllable pitch propellers compared to fixed pitch propellers: • Secure and precise manoeuvrability • An increase in the average speed • Stern tube wear is reduced • A constant speed at engine is possible • Easy replacement of spare blades • Engine wear is minimized • Reduced fuel costs • Dynamic position of vessel possible • Stepless speed control of the ship • Load control of engine is possible • Full power available under all conditions • The propeller can be designed for free running and towing 

Propeller Design All ships have individual needs. Speed is important for some ships. Towing pull is more important for others. To satisfy these needs Finnøy use the most suitable software together with Finnøy’s knowledge when designing propeller blades. The propeller blade is designed for best possible performance regarding thrust, efficiency, noise and vibration. The blades are ground and balanced according to ISO 484 standards.

Nozzle With ships that need maximum towing thrust a nozzle could be fitted. The nozzle increases the bollard pulls by approx 30%-40% over an open propeller absorbing the same power. It can be delivered as a steering or fixed nozzle.

PROPELLERS

Main types: -Controllable pitch (CP) propellers -Propellers with shaft hydraulic servo -Adjustable propellers Nogva CP propellers are constructed to fit transmissions with built in servo systems for pitch control (like all Nogva Gears). The C.P. propellers pull rod is connected with flanges to the servo system and propeller pitch is altered when the pull rod moves. Propellers with shaft hydraulic servo can be used with all types of transmissions. The hydraulic cylinder is fitted to the shaft and an axial running piston is controlled with a hydraulic hand pump. One or more such hand pumps can be used.With adjustable propellers you can adjust the propeller pitch from outside the boat when the vessel is on slipway. Common: All Nogva Propellers are now 3-blade and of type B-series.

EFFECT RUDDERS	Our effect rudder is a part of our controllable pitch propeller (CPP) system, and is designed as an airfoil, providing a lift in the water flow, which again produces a forward thrust. This results in a minimum drag on the rudder.
PROPELLER TUNNELS	Conventional propulsion systems, such as propellers or water jets, work most efficiently in open water conditions. In Servogear we develop tailor-made propeller tunnels as a part of our controllable pitch propeller system, to provide greater propulsion efficiency below a hull than in open water. The propeller tunnel itself also reduces hull resistance. Our propeller tunnel allows for larger propeller diameter with no increase of shaft angle and draught. Propeller rpm is reduced, as well as the surface pressure on the propeller blades, and the water flow entering the propeller is optimised. Together with other detail improvements, this provides the best possible working conditions - resulting in a smooth and efficient propeller thrust. A more even loaded propeller gives a slimmer and lighter design, which means less weight and drag as well as higher efficiency. We calculate and design our propeller tunnels based on full utilisation of the flow below the hull, ensuring optimum interaction between hull and propulsor. Efficient propulsion means lower fuel consumption, more economic operation and less pollution.
PROPELLERS	Servogear Ecoflow PropulsorTM is a unique controllable pitch propeller (CPP) system for high-speed workboats, fast ferries, offshore vessels and yachts. The concept offers an optimal combination of speed, bollard pull, manoevrability and fuel efficiency. Learn more about CPP here (Kasten Marine Design). Through continuous theoretical and practical research since 1973, we have developed an incredibly efficient propeller system. These are successfully running on a large number of vessels worldwide. Search in our selected references catalog here. The Servogear CPP system covers an engine range of 400 to 4000 kW and speed up to 50 knots.
