Product catalog summary
Introduction
The document introduces the next generation of Fixed Pitch Propellers (FPP) by MAN Alpha, featuring replaceable propeller blades. This innovation aims to enhance design, handling, and performance.

Key Benefits
  • High efficiency and low noise operation.
  • Robust design with a pyramidal strength principle.
  • Spare blades can be used as spare parts, eliminating the need for a complete spare propeller.
  • Blades can be replaced underwater, avoiding dry-docking.
  • Easy and cost-efficient transport, handling, and installation.
  • Minimized downtime in case of blade damage.

Design and Performance
The propeller features a compact hub design and hydrodynamically optimized blades, offering superior propulsive efficiency and minimal fuel consumption. The hub and blade designs reduce weight and inertia, enhancing efficiency. Versions with 2 to 7 blades are available, and the hub can be combined with EcoCap or fairing cone for EcoBulb installations.

Hub and Shaft Connection
The propeller uses a bolted principle with hydraulic tensioning for secure handling and a reliable hub/shaft junction.

Flexibility and Application
Ideal for operations in challenging environments such as ice-packed areas or waters with debris, where long dry-docking is critical. The design meets extreme class requirements up to the highest polar ice classes.

Materials and Construction
Standard materials include NiAl-Bronze and stainless steel. The propeller is designed using the pyramidal strength principle, ensuring robustness and reliability.

Conclusion
The MAN Alpha FPP is tailored for specific propulsion plants, minimizing hub diameter, length, and weight, and is designed to withstand extreme impacts in rugged operations.

MAN Alpha FPP-2

Fixed pitch propeller with replaceable blades Tailored, compact and reliable The propeller and hub are tailor-made for each specific propulsion plant in order to minimize the hub diameter, the length and the weight. Mechanically, the propeller is designed by use of the pyramidal strength principle, meaning that blade foot, blade bolt connection, hub and propeller shaft connection are stronger than the blade itself – making the propeller very robust and very reliable for withstanding possible extreme impacts in rugged operation. High ice class – ice breaker version in stainless steel. High performance...
