Propeller & Aft Ship Solutions  Page 06 | 07 Propelling ships and trade on all seas and waterways From the early days of invention and shipboard deployment of a ‘screw propeller’, the principle of which can be dated back to Archimedes – the propellers have just developed decade by decade and grown in size, power density and design complexity. The propellers’ transmission of rotational power and torque into thrust and ship propulsion turned out more and more efficiently. Today’s propeller demands and propulsion benchmarks for the individual ship applications have become very specific,...

KAPPEL DESIGN Unique propeller blade design gains the highest efficiencies MAN Diesel & Turbo is offering the fuel-saving Kappel program for FP Propellers and for CP Propellers – meaning that the full range of MAN Alpha propellers is available with propeller blades of Kappel design. For retrofit upgrades numerous monoblock FP Propellers have been exchanged with Kappel, and also other makes of CP Propellers have successfully been fitted with the more efficient Kappel blades. Geometrically, the Kappel propeller design is characterized by non-planar lifting surfaces and blade geometry, by...
