Excerpt from The Design of Marine Engines and Auxiliaries
The production of a book upon marine engine design must necessarily involve the use of material from many sources. It is so difficult to determine the ultimate source of all tills material that the author has not attempted the task. It is far easier to point out those portions of the book which have some degree of originality and then to make a general acknowledgment of indebtedness for the remainder.
So far as the author knows the following methods are original: the method of design (§§ 13 to 22), the method of obtaining mean bearing loads (§§ 86 to 90), the use of the mean lead in the solution of valve diagrams (§ 105), the method of designing condensers (§ 156), the method of designing turning engines (§§ 173 to 177).
In the section on Engine Balancing, although no portion of the material is original, much time and effort has been expended in correlating the work of various investigators.
The question of pressures upon main bearings will be found more extensively treated in a paper by the author in Vol. 18, Part I, of The Journal of the American Society of Naval Engineers.
The author wishes to acknowledge the kindness of the Newport News Shipbuilding and Dry Dock Company in permitting him to use certain drawings for Plates 1, 2, and 3.
