Excerpt from On Technological Education and the Construction of Ships and Screw Propellers, for Naval and Marine Engineers A second edition of this work has been called for, and as Congress has taken no action on the subject, the author avails himself of the opportunity to add further arguments in favor of technological education. The topic cannot be too much discussed, and certainly merits the serious consideration of every good citizen. There are many engineers in the Navy who would be equally disposed, to agitate this subject and assist in the reorganization and improvement of the corps, but their position restrains them, and they cannot expose themselves to the ungrateful task, which is unavoidable in the elucidation of the existing system. The lot seems to have fallen on the author to take the bull by the horns, and he fearlessly courts an open contest, if such can only be had, with the organized prejudices which now embarrass the subject. If in fault, he is open for correction. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

On Technological Education and the Construction of Ships and Screw Propellers - For naval and marine engineers is an unchanged, high-quality reprint of the original edition of 1866. Hansebooks is editor of the literature on different topic areas such as research and science, travel and expeditions, cooking and nutrition, medicine, and other genres. As a publisher we focus on the preservation of historical literature. Many works of historical writers and scientists are available today as antiques only. Hansebooks newly publishes these books and contributes to the preservation of literature which has become rare and historical knowledge for the future.

Excerpt from The Screw Propeller: And Other Competing Instruments for Marine Propulsion Some thirty-two years ago, when engaged in putting forth the Manual of Marine Engineering, I could not find a single book on the Screw Propeller, or any text book containing such information on it as would enable a draughtsman to get out the leading dimensions, and much less to make a complete design of a screw suitable for any particular ship and conditions. At that time John Bourne's admirable book on the Screw Propeller was not only out of print, but out of date, and I fear no engineer could at any time have designed a screw which would give satisfactory results from what was contained in it. It was, however, many years after that I first saw his work, and my wonder then, as now, is that such a book was allowed to disappear, seeing how much of interest it contained. But perhaps the strongest comment on the knowledge of the screw propeller at that time is in the admission of the then engineer-in-chief of the British Navy, that he had settled the design of those for so very important a ship as the Iris, intended to be the fastest ship in the Navy, by copying that of hms. Himalaya, a ship built in 1854, with the result that the British Admiralty, with all its knowledge and opportunities, with all its records of tests and trials, perpetrated a blunder never equalled in the history of steam navigation, although in the mercantile marine there had been not a few mistakes. But even in modern times, notwithstanding the better knowledge and the aid of tank experiments, our best men do sometimes fail to achieve success, but the magnitude of the failure is inconsiderable compared with that of the Iris. In the Manual of Marine Engineering I attempted to supply the wants of designers by giving a rule or formula for each important dimension, generally based on scientific reasons, and always capable of giving results agreeable with the best and most successful practice.

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
