Book Description
Marine Propellers and Propulsion, Fourth Edition, offers comprehensive, cutting edge coverage to equip marine engineers, naval architects or anyone involved in propulsion and hydrodynamics with essential job knowledge. Propulsion technology is a complex, multidisciplinary topic with design, construction, operational and research implications. Drawing on experience from a long and varied career in consulting, research, design and technical investigation, John Carlton examines hydrodynamic theory, materials and mechanical considerations, and design, operation and performance. Connecting essential theory to practical problems in design, analysis and operational efficiency, the book is an invaluable resource, packed with hard-won insights, detailed specifications and data. - Features comprehensive coverage of marine propellers, fully updated and revised, with new chapters on propulsion in ice and high speed propellers - Includes enhanced content on full-scale trials, propeller materials, propeller blade vibration, operational problems and much more - Synthesizes otherwise disparate material on the theory and practice of propulsion technology from the past 40 years' development, including the latest developments in improving efficiency - Written by a leading expert on propeller technology, essential for students, marine engineers and naval architects involved in propulsion and hydrodynamics

Book Description
This phase of the Icebreaker Propulsion System Simulation reports on the results of studies directed at improving the overall in-ice icebreaker performance through improved propulsion system design. A mathematical description of the ice-torque problem for dynamic and quasi-steady state behavior is presented, and additional propulsion system electrical circuit dynamics necessary to more adequately describe propulsion system dynamic behavior during propeller-ice encounters are described. The predicted performance of the USCGC GLACIER when subjected to the ice load torque model is presented. A load control scheme (designed to extend the constant horsepower range of the propulsion system well below bollard propeller speed) is developed and incorporated into the basic system equations. The performance of a system of the same size as the GLACIER incorporating this load control system and subjected to the same ice loads is also presented. It is concluded that the incorporation of a load control system significantly increases the capability of the icebreaker propulsion system when operating in ice. (Author).

Book Description
"A series of tests on a model of the ice class fixed pitch propeller of the Canadian Coast Guard's R-Class icebreakers were conducted in the towing tank at Memorial University of Newfoundland. Performance of the propeller was assessed in both uniform flow and in blocked flow behind a nearby simulated ice piece for two blockage configurations and a range of clearances between the block and the propeller blades. Measurements of thrust and torque were made over a range of speeds. The results help to isolate the separate effects of the extreme wake within which the propeller operates, and of proximity of the ice piece. The work forms part of a broader research effort examining the performance of propellers when blocked with ice"--Leaf [1].

Book Description
Although the propeller lies submerged out of sight, it is a complex component in both the hydrodynamic and structural sense. This book fulfils the need for a comprehensive and cutting edge volume that brings together a great range of knowledge on propulsion technology, a multi-disciplinary and international subject. The book comprises three main sections covering hydrodynamics; materials and mechanical considerations; and design, operation and performance. The discussion relates theory to practical problems of design, analysis and operational economy, and is supported by extensive design information, operational detail and tabulated data. Fully updated and revised to cover the latest advances in the field, the new edition now also includes four new chapters on azimuthing and podded propulsors, propeller-rudder interaction, high-speed propellers, and propeller-ice interaction.·The most complete book available on marine propellers, fully updated and revised, with four new chapters on azimuthing and podded propulsors, propeller-rudder interaction, high-speed propellers, and propeller-ice interaction·A valuable reference for marine engineers and naval architects gathering together the subject of propulsion technology, in both theory and practice, over the last forty years ·Written by a leading expert on propeller technology, essential for students of propulsion and hydrodynamics, complete with online worked examples
