Propulsion technology is a complex, multidisciplinary topic with design, construction, operational and research implications. Bringing together a wealth of disparate information from the field, Marine Propellers and Propulsion provides comprehensive and cutting edge coverage to equip marine engineers, naval architects and anyone involved in propulsion and hydrodynamics with the knowledge needed to do the job. Drawing on experience from a long and varied career in consultancy, research, design and technical investigation, author John Carlton breaks the subject into three main sections - hydrodynamic theory, materials and mechanical considerations, and design, operation and performance. Connecting essential theory to practical problems in design, analysis and operational efficiency, Marine Propellers and Propulsion is an invaluable resource, packed with hard-won insights, detailed specifications and data. The most complete book available on marine propellers, fully updated and revised, with new chapters on propulsion in ice and high speed propellers Gathers together 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

Not illustrated. 1895 edition. Excerpt: ...surface, or wave, noticeable above a revolving screw. In an account of the speed trial of the triple-screw U. S. S. "Columbia" the following is related: "The most noticeable feature of the trial of the ship itself was the remarkable absence of all wave. The triangular foaming cataract at the stern formed with its apex about ten feet from the ship and then subsided in height as it spread in width, until it disappeared fifty feet further aft into a series of gentle waves, similar to those which are seen in the wake of a stern-wheel steamboat." In some instances where the screws revolve very rapidly, and the form of the after part of the vessel and position of the screws are favorable for it, the elevation resulting from the discharge of screws is excessive. In the case of the torpedo boat " Cushing " it attains a height of three or four feet above the normal surface. When the immersion of the screw is sufficient, there may be little or no noticeable elevation of surface over it, because the discharged water will be widely dispersed and equilibrium will be restored before the surface can be affected to a sensible degree. In Trans. Inst. Nav. Arch., 1879, Mr. Griffiths recites the results of experiments he was allowed to make on H. M. steam pinnace No. 22 in 1875 by measuring, with apparatus specially constructed for the purpose, the rate at which the water flowed through the screw disk while the boat was being towed. These experiments showed that over the bottom half the water was little interfered with, but at the top half of the disk the water was dragged with the boat to a certain extent, and only flowed through the screw at about half the speed of the boat's progress. When a ship is being driven by a screw...
