Book Synopsis Considerations on Propeller Efficiency by : Albert Betz
Download or read book Considerations on Propeller Efficiency written by Albert Betz and published by . This book was released on 1928 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: The propeller cannot be considered alone, but the mutual interference between propeller and airplane must be considered. These difficulties are so great when the joint action of propeller and airplane is considered, that the aerodynamic laboratory at Gottingen originally abandoned the idea of applying the efficiency conception of the test results. These difficulties and the methods by which they are overcome are outlined in this report.
Book Synopsis Propeller Selection from Aerodynamic Considerations by : John L. Crigler
Download or read book Propeller Selection from Aerodynamic Considerations written by John L. Crigler and published by . This book was released on 1942 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical analysis is presented of the performance of propellers extending to high values of V/nD. At high values of V/nD the analysis shows the propeller efficiency to be critically dependent on the distribution of the load along the radius. A method of calculating the pitch distributions of optimum propellers is explained. Charts are presented that facilitate the selection of the most efficient propellers over a wide range of operating conditions. It is noted that experimental data in the range of high values of V/nD for the purpose of establishing the optimum load distribution are essentially lacking.

Book Synopsis Charts for Determining Propeller Efficiency by : John L. Crigler
Download or read book Charts for Determining Propeller Efficiency written by John L. Crigler and published by . This book was released on 1944 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: A short method of estimating propeller efficiency for a given operating condition is described. The efficiency is determined for any design condition by evaluating separately from charts the induced losses and the profile-drag losses. The estimated efficiency is compared with experimental results for a wide range of operating conditions and found to be in agreement near peak efficiency. The present analysis covers single-rotating propellers of two, three, four, six, and eight blades and includes charts showing the rotational-energy loss for the given operating condition in order to assist in estimating the gain in efficiency for dual-rotating propellers. The change in efficiency to be expected from body interference is discussed. Two examples illustrating the use of the method are given in an appendix.
Book Synopsis Analysis of Propeller Efficiency Losses Associated with Heated-air Thermal De-icing by : Blake W. Corson
Download or read book Analysis of Propeller Efficiency Losses Associated with Heated-air Thermal De-icing written by Blake W. Corson and published by . This book was released on 1946 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis is made of the loss of efficiency associated with a heated-air thermal de-icing propeller both with and without internal flow. For the available data, measured efficiency losses are compared with the calculated losses and the agreement is found to be within the experimental accuracy of the data. The method presented may be used with reasonable accuracy to determine the net change in propeller efficiency due to the combined effects of the nozzle and internal flow if the characteristics of the propeller without nozzles are known.

Book Synopsis Practical Ship Hydrodynamics by : Volker Bertram
Download or read book Practical Ship Hydrodynamics written by Volker Bertram and published by Elsevier. This book was released on 2012 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Ship Hydrodynamics provides a comprehensive overview of hydrodynamic experimental and numerical methods for ship resistance and propulsion, maneuvering, seakeeping and vibration. Beginning with an overview of problems and approaches, including the basics of modeling and full scale testing, expert author Volker Bertram introduces the marine applications of computational fluid dynamics and boundary element methods. Expanded and updated, this new edition includes: Otherwise disparate information on the factors affecting ship hydrodynamics, combined to provide one practical, go-to resource. Full coverage of new developments in computational methods and model testing techniques relating to marine design and development. New chapters on hydrodynamic aspects of ship vibrations and hydrodynamic options for fuel efficiency, and increased coverage of simple design estimates of hydrodynamic quantities such as resistance and wake fraction. With a strong focus on essential background for real-life modeling, this book is an ideal reference for practicing naval architects and graduate students.
