This book was released on 1961 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A procedure for calculating the spindle torque and for determining the optimum spindle axis location of a controllable-pitch propeller at design conditions is presented. From the blade geometry and theoretical pressure distribution the hydrodynamic and centrifugal forces acting on the blade are obtained, and from the distribution of these forces the spindle torque is calculated. The optimum spindle axis location is then determined by an iteration process. An example is included to illustrate the procedure. (Author).

This book was released on 1975 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental results are presented on the spindle torque and open-water performance of two skewed controllable-pitch propellers. Both propellers have radial distributions of skew specified so that the section midchord is forward of the spindle axis at the inner radii and aft of the spindle axis at the outer radii. One propeller has no rake and the other has substantial forward rake. The experiments were conducted at steady conditions in uniform flow in a towing basin over a range of positive and negative pitch ratios and a range of positive and negative advance coefficients so that the complete maneuvering envelope of the ship was simulated in a quasi-steady manner. The experimental open-water performance was correlated with calculated values based on a least-squares fit to previous systematic experimental data.

This book was released on 1975 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical method for the analysis of controllable pitch propeller characteristics is presented. This inverse problem is complicated due to the unknown circulation distribution and the off-design blade geometry. Therefore, a normal mode collocation method is introduced which simplifies the problem by a combination of design approaches. Starting with the transformation of blade geometry resulting from rotation about the spindle axis, a numerical lifting-surface computation is then applied on the exact three-dimensional basis and solved for the amplitude of each mode by collocation in order to obtain the circulation distribution and the thrust and torque thereof. The work has been modified by a reconstructed vortex lattice distribution and the consideration of hub image and deformed wake effect so that the accuracy is improved.

Available in PDF, EPUB and Kindle. Book excerpt: The Maritime Engineering Reference Book is a one-stop source for engineers involved in marine engineering and naval architecture. In this essential reference, Anthony F. Molland has brought together the work of a number of the world's leading writers in the field to create an inclusive volume for a wide audience of marine engineers, naval architects and those involved in marine operations, insurance and other related fields. Coverage ranges from the basics to more advanced topics in ship design, construction and operation. All the key areas are covered, including ship flotation and stability, ship structures, propulsion, seakeeping and maneuvering. The marine environment and maritime safety are explored as well as new technologies, such as computer aided ship design and remotely operated vehicles (ROVs).Facts, figures and data from world-leading experts makes this an invaluable ready-reference for those involved in the field of maritime engineering.Professor A.F. Molland, BSc, MSc, PhD, CEng, FRINA. is Emeritus Professor of Ship Design at the University of Southampton, UK. He has lectured ship design and operation for many years.
