CONTROLLABLE PITCH PROPELLERS FOR SMALL FAST WARSHIPS AND PATROL CRAFT

This paper deals with the development and status of controllable-pitch (CP) propellers mainly for multiple-screw, high-speed small warships and gives viewpoints on the performance of various installations with Diesel engines and/or gas turbines developed by AB Karlstads Mekaniska Werkstad (KMW) for use by the Swedish Navy. Brief details are given of the twin-piston CP propeller hub and the feathering CP propeller hub designed by KMW to improve manoeuvrability and overcome cavitation problems. Supercavitating CP propeller designs under development by KMW are reviewed and the paper concludes with a summary of the special requirements for CP propellers for small fast craft. Order from BSRA as No. 49,970.
