Propeller aft ship solutions CP pro peller Highly efficient MAN Alpha propulsion

MAN Alpha CP Propellers A high-efficient VBS Mk 5 generation MAN Energy Solutions 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 Energy...

Advanced hydrodynamics The basis for increased propeller efficiency For maintaining and developing MAN Energy Solution'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 Energy Solutions cooperates with the world's leading test tanks and research institutes. Hydrodynamic design characteristics of Mk 5 The shape of hub is flow-optimized at its afterpart Operational advantages Increased...

VBS Mk 5 propeller with 1,450 mm hub diameter – five-bladed version

Mechanical optimization 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 optimized 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 Alphatronic 3000 in control 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 Bridge 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. Three levels of propulsion control Engine Control Room Normal control with automatic load control Backup control from bridge and ECR Independent telegraph system...

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 very compact ODF oil distribution unit – for gearbox An oil distribution unit – specifically tailored to shaft mounting – has been developed for the VBS Mk 5 installation in direct coupled low speed engine plants propellers. A short and very robust unit with 20% few- is also part of the VBS Mk 5 programme. er parts...

Propulsion package layout The perfect match begins with the propeller COPS – a unique layout tool COPS is an abbreviation for Computerized Optimization of Propulsion Systems. MAN Energy Solution's COPS expert system ensures better and more accurate preoptimisation of hydrodynamic/mechanical aspects – with additional consideration to e.g. statistical data, PTI/ PTH, torsional vibration calculations and more. The VBS Mk 5 range offers excellent coverage of any propeller demand 20 standard four-bladed hub sizes range from 600 to 2,150 mm, corresponding to a power range from 1,000 kW and up to...

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. Stern tube/shaft/bearing systems are as standard customized for oil lubrication. Water lubricated systems are available upon request. 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...
