General DescriptionMAN B&W Alpha have manufacturedmore than 6,000 controllable pitch propellersof which the first was producedin 1902.The basic design principle is well–proven, having been operated in alltypes of vessels including ferries,cruise and supply ships etc, many ofwhich comply with high classificationrequirements.Today the MAN B&W Alpha controllablepitch propeller equipment typesVB and VBS are handling engine outputup to 20,000 kW, fig 1.Controllable pitch propellers can utilizefull engine power by adjusting bladepitch irrespective of revolutions orconditions.They offer not only maximum speedwhen free sailing, but also maximumpower when towing, good manoeuvrabilitywith quick response via the remotecontrol system and high asternpower.These are just a few of many advantagesachieved by controllable pitchpropellers.Propeller Diameter [mm]800070006000VBS16805000VBS1560400030002000VBS740VBS860VBS980VBS1080VBS1180VBS1460VBS1280 VBS1380100000 2000 4000 6000 8000 10000 12000 14000 16000 18000 20000Engine Power [kW]Fig 1: VBS propeller equipment programme for no ice class notationThis document, and more, is available for download at Martin's Marine Engineering Page - www.dieselduck.net5
