Written by experts in the ship design field, this book provides a comprehensive approach to evaluating ship resistance and propulsion.

This richly illustrated manual is a comprehensive yet practical guide to the installation, operation, and maintenance of propulsion systems for scale model ships. Beginning with model and propulsion system options, the author goes on to describe both electric and steam systems, including the fitting and care of battery packs, radio controls and the operation of steam boilers, with an emphasis on safety when dealing with pressurized containers. Paddle-wheels and screw propellers are covered as well as such specialized propulsion units as variable-pitch propellers, azimuth thrusters, and Voith Schneider units Lavishly illustrated with photographs and the author's own technical line drawings and complemented by the inclusion of data tables and appendixes with addresses of suppliers of materials and equipment this eminently practical and useful handbook is indispensable reading for all working ship modelers.

Next to railways, they are the epitome of historical technology: steamships. No wonder, then, that they also have a special appeal for model builders. To drive one's model not simply with an electric motor, but even more originally with a steam engine, is the dream of many technology fans. If the model then moves across the pond, trailing a plume of steam behind it, the enthusiasm is perfect! But how do you build such a model? What are the possibilities? Which models are suitable? These and many more questions are answered in detail by steamship specialist Thomas Hillenbrand in this book. In addition to the basics of technology and construction, he looks at various types of models, most of which he has successfully built himself - some of them very unusual constructions. The book concludes with an example of the construction of a steamship with a simple superstructure - an ideal introduction to this fascinating branch of model building. So, open the throttle and full steam ahead! From the content: • Some of the history of steam-powered ships and models • Steam as a source of power • The steam boiler • Some information about combustion and the firing of steam boilers • The different versions of the propulsion engine • Commissioning, troubleshooting and repair of the steam system • The propulsion systems of the steamship • Suitable models for steam propulsion • Installation of the steam system in the model • Presentation of different steamship models • Building the Steam Launch Presto

The early development of the screw propeller. Propeller geometry. The propeller environment. The ship wake field, propeller performance characteristics.

A comprehensive guide to the building and sailing of working scale model merchant ships, this new paperback edition covers the spectrum of ship types--from tankers to trawlers to paddle-steamers. Every stage of construction is covered in full detail, beginning with the building of the hull and concluding with propulsion, ballasting, and sailing the completed model. All building methods and materials are described, including plank on frame construction, GRP molding of hulls, and casting of deck fittings. Chapters are devoted to the installation of electric motors and steam engines, and the fitting and operation of radio control equipment. This book is indispensable reading for ship modelers of all skill levels.

The propulsion system behaviour is a key aspect for the overall dynamics of a ship. However, despite its great importance, numerical methodologies for detailed investigations on marine propulsion dynamics are not yet widely covered in scientific literature. This book presents the main steps for the development of a multi-physic simulation platform, able to represent the motions of a twin screw ship in six degrees of freedom, taking into account the whole propulsion system and automation effects. A number of mathematical sub-models had been developed and calibrated by a set of experimental tests, in model and full scale. Finally, the sea trials campaign of a ship is used to validate and tune the developed simulator. The proposed simulation methodology can be used in the ship preliminary design phase, in order to plan and test the propulsion system and automation. Further applications can include the design optimization and crew training.

RC ship models with jet propulsion or water jet propulsion, as you can also say, have been around for many years, but unfortunately only a few model ship builders have familiarised themselves with this type of propulsion. Once you have read this book and seen the many illustrations of jet models, you will also be one of the jet-enthusiastic RC model ship builders. The author explains the technology and you will find that building a jet-powered RC model ship is no more difficult than building a model with conventional propulsion. Numerous pictures illustrate the construction and conversion of models, so that every beginner will be able to venture into building a jet-powered RC ship model. From the content: • How a jet propulsion system works • First model ship kits with jet propulsion • A company specialises in jet propulsion • Building instructions for RC ship models with jet propulsion • Jet models from Kehrer material sets • Model Ruban Bleu with one jet engine • Model Antipodean with two jet engines • Model SAR 33 with three jet drives • Other models with Kehrer jet drives • Model Motor Yacht Thor • Model HMCC Sentinel • Model Florida-Jet • Model Rapido 600-Jet • Experimental model Wave Explorer-Jet • Racing catamaran Powerkat-Jet • Pictures of some more Kehrer-Jet models • Multi Jet-Boat from Graupner

Practical Ship Hydrodynamics provides a comprehensive overview of hydrodynamic experimental and numerical methods for ship resistance and propulsion, maneuvering, seakeeping and vibration. Beginning with an overview of problems and approaches, including the basics of modeling and full scale testing, expert author Volker Bertram introduces the marine applications of computational fluid dynamics and boundary element methods. Expanded and updated, this new edition includes: Otherwise disparate information on the factors affecting ship hydrodynamics, combined to provide one practical, go-to resource. Full coverage of new developments in computational methods and model testing techniques relating to marine design and development. New chapters on hydrodynamic aspects of ship vibrations and hydrodynamic options for fuel efficiency, and increased coverage of simple design estimates of hydrodynamic quantities such as resistance and wake fraction. With a strong focus on essential background for real-life modeling, this book is an ideal reference for practicing naval architects and graduate students.

Fundamentals of Ship Hydrodynamics: Fluid Mechanics, Ship Resistance and Propulsion Lothar Birk, University of New Orleans, USA Bridging the information gap between fluid mechanics and ship hydrodynamics Fundamentals of Ship Hydrodynamics is designed as a textbook for undergraduate education in ship resistance and propulsion. The book provides connections between basic training in calculus and fluid mechanics and the application of hydrodynamics in daily ship design practice. Based on a foundation in fluid mechanics, the origin, use, and limitations of experimental and computational procedures for resistance and propulsion estimates are explained. The book is subdivided into sixty chapters, providing background material for individual lectures. The unabridged treatment of equations and the extensive use of figures and examples enable students to study details at their own pace. Key features: • Covers the range from basic fluid mechanics to applied ship hydrodynamics. • Subdivided into 60 succinct chapters. • In-depth coverage of material enables self-study. • Around 250 figures and tables. Fundamentals of Ship Hydrodynamics is essential reading for students and staff of naval architecture, ocean engineering, and applied physics. The book is also useful for practicing naval architects and engineers who wish to brush up on the basics, prepare for a licensing exam, or expand their knowledge.

This book gathers the peer-reviewed proceedings of the 14th International Symposium, PRADS 2019, held in Yokohama, Japan, in September 2019. It brings together naval architects, engineers, academic researchers and professionals who are involved in ships and other floating structures to share the latest research advances in the field. The contents cover a broad range of topics, including design synthesis for ships and floating systems, production, hydrodynamics, and structures and materials. Reflecting the latest advances, the book will be of interest to researchers and practitioners alike.
