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.
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. Over a long and distinguished career he has authored more than a hundred technical papers and articles on marine technology, received numerous awards, chaired international committees and contributed to various government and naval initiatives on maritime matters.
Marine Propellers and Propulsion
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.

Propeller, Types of Propellers and Construction of Propellers
A propeller is a rotating fan-like structure which is used to propel the ship by using the power generated and transmitted by the main engine of the ship. The transmitted power is converted from rotational motion to generate a thrust which imparts momentum to the water, resulting in a force that acts on the ship and pushes it forward. A pressure difference is created on the forward and aft side of the blade and water is accelerated behind the blades. A ship can be fitted with one, two and rarely three propellers depending upon the speed and manoeuvring requirements of the vessel. Marine propellers are made from corrosion-resistant materials as they are made operational directly in seawater which is a corrosion accelerator. The materials used for making marine propeller are an alloy of aluminium and stainless steel. The construction process of the propeller includes attaching a number of blades to the hub or boss by welding or forging in one piece.

A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral, that, when rotated, performs an action which is similar to Archimedes' screw. It transforms rotational power into linear thrust by acting upon a working fluid, such as water or air. A given mass of working fluid is accelerated in one direction and the craft moves in the opposite direction. Propeller dynamics, like those of aircraft wings , can be modelled by Bernoulli's principle and Newton's third law. The principle employed in using a screw propeller is derived from sculling.
Что ты говоришь? - засмеялся Стратмор. - Что же ты предлагаешь. Открыть дверь и вызвать сотрудников отдела систем безопасности, я угадал.
Пятидесятишестилетний коммандер Стратмор, заместитель оперативного директора АНБ, был для нее почти как отец. Именно он принимал ее на работу, именно он сделал АНБ для нее родным домом. Когда десять лет назад Сьюзан поступила в агентство, Стратмор возглавлял Отдел развития криптографии, являвшийся тренировочной площадкой для новых криптографов, криптографов мужского пола.
Интересно, какие он строит планы. Обнародует ли ключ. Или жадность заставит его продать алгоритм. Она не могла больше ждать.
