Engineering the Future - since 1758.

MAN Alpha CP Propellers A high-efficient VBS Mk 5 generation MAN Diesel & Turbo is proud to present a high-efficient VBS propeller generation, which has been developed on the basis of the industry's state-of-the-art design tools combined with the vast experience accumulated from more than 7,000 propellers. A long tradition and a proud propeller heritage date back to the first Alpha CPP design, which was produced in 1902 and patented in 1903. Flexibility for covering efficiently any propulsion power requirement and CP Propeller application is the overall product target for MAN Diesel &...

Advanced Hydrodynamics The basis for increased propeller efficiency For maintaining and developing MAN Diesel & Turbo's position in the propulsion forefront, many resources are invested and the latest advanced design tools including e.g. CFD (Computational Fluid Dynamics), FEM (Finite Element Methods) and Topology Optimisation are deployed. To verify the calculations, MAN Diesel & Turbo cooperates with the world's leading test tanks and research institutes. Hydrodynamic design characteristics of Mk 5 Operational advantages Increased propeller efficiency is translated into sav- afterpart and...

The VBS Mk 5 propeller – medium-size 1,020 mm hub diameter

Mechanical Optimisation Even higher operational reliability Less is more: The new hub design is simplified with approx. 40% fewer parts. The MAN Alpha Propeller reliability and durability have always been very high, and the Mk 5 design extends that design philosophy. Additionally, the overall weight has been reduced for less impact on strut and stern tube bearing loads. Mechanical design characteristics Robust approach – with ample design margins reduction of 15% – ensuring a well-balanced load Material fatigue levels calculated for a 30 year lifetime, considering all possible external...

Novel blade and blade foot design features ■ The 'multi-radius-fillet' design reduces the blade weight by approx. 4% and contributes to a higher cavitation inception speed ■ The optimised hub/blade interface allows for higher propulsion power densities. Operational advantages ■ Low wear rates and a very long lifetime ■ Higher reliability with fewer components ■ Reduced bearing loads due to lower weight ■ Smaller hub dimensions resulting in higher efficiency ■ Large pitching range and great manoeuvrability ■ Increased service and inspection friendliness.

Electro-Hydraulic Pitch Setting Precise manoeuvring and propeller control Control is crucial: Safe and accurate propulsion management all the way – from the navigator's finger tips to the propeller tips. Any pitch manoeuvring order given from one of the control consoles is translated into electrical signals, governing the hydraulic servo oil via the oil distribution unit to the CPP servo cylinder for pitch setting.

The new ODF for the Mk 5 propeller design includes a unique 100% linear feedback system – a contact-less ultrasonic design with no use of linkage bars. No wear and no hysteresis in feedback. Servo oil working pressure up to 90 bar Shaft-mounted ODS unit for low speed plants A new, very compact ODF oil distribution unit – for An oil distribution unit – specifically tailored to shaft gearbox mounting – has been developed for the VBS installation in direct coupled low speed engine plants Mk 5 propellers. A short and very robust unit with is also part of the VBS Mk 5 programme. 20% fewer parts...

Propulsion Package Layout The perfect match begins with the propeller COPS – a unique layout tool COPS is an abbreviation for Computerised Optimisation of Propulsion Systems. MAN Diesel & Turbo's COPS expert system ensures better and more accurate pre-optimisation of hydrodynamic/mechanical aspects – with additional consideration to e.g. statistical data, PTI/PTH, torsional vibration calculations and more. The new VBS Mk 5 range offers excellent coverage of any propeller demand 20 hub sizes will range from 600 mm and up to 2,150 mm, corresponding to an approx. power range of 1,000-40,000...

The propellers are prepared for biodegradable servo and lube oils. The servo oil and lube oil systems are adapted to both biodegradable oils and ordinary mineral oils. Switching from one type to the other is possible without any requirements for component changes Tailored propeller systems and plant solutions: Efficient and compact propulsion packages with an even shorter required installation length, e.g. due to the new ODF oil distribution unit, are shown in the above installation with a Renk gearbox and an MAN 8L32/44CR propulsion engine. Special options for special requirements MAN...
