Controllable pitch propellers are used to propel a large number of vessels of many types. This informative book provides an essential understanding of the characteristics, construction, operation and maintenance of controllable pitch propellers. Those responsible for selecting and designing machinery systems, building and commissioning ships with controllable pitch propellers, managing or sailing them, or operating and maintaining ship's machinery, will all find useful practical information and gain a general appreciation of the subject.

Topics covered include a brief history, characteristics of controllable pitch propellers and their resultant applications, definitions of terms used, forces and moments on blades, constructional and working principles, descriptions of hydraulic and control systems installation design and setting-up, operation, ship handling, troubleshooting, and maintenance. In addition there is a discussion of the types of cavitation wich any be experienced, of erosion and of propeller excited noise and vibration.

Written in a clear and interesting style, wich does not require specialist knowledge, and backed up by 37 explanatory diagrams and illustrations, this title will be of use to marine engineering students as well as proving a useful reference for both seagoing and design engineers.
