In the course of time, many attempts have been made to invent, develop, or to improve hydrodynamic propulsion devices. Remarkable achievements in this field were made essentially by experienced individuals, who were in need of reliable propulsion units such as paddle wheels, sculling devices, screw propellers, and of course, sails. The problem of minimizing the amount of input energy for a prescribed effective output was first investigated seriously at the beginning of this century. In 1919, BETZ presented a paper on air-screw propellers with minimum consumption of energy which could be applied to ship-screw propellers also. Next, attempts were made to optimize hydrodynamic propulsion units. Ensuing investigations concerned the optimization of the hydrodynamic system: ship-propeller. The first simple theory of ship propulsion which was presented considered more or less only thrust augmentation, wake processing and modification of propeller characteristics when operating behind the ships hull. This theory has been little improved meanwhi | | 出版日期 | Book 1995 | | 关键词 | Propeller; dynamics; optimization | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-017-1812-7 | | isbn_softcover | 978-90-481-4484-6 | | isbn_ebook | 978-94-017-1812-7Series ISSN 0926-5112 Series E-ISSN 2215-0056 | | issn_series | 0926-5112 | | copyright | Springer Science+Business Media Dordrecht 1995 |
