This second edition provides a comprehensive and scientific approach to evaluating ship resistance and propulsion. Written by experts in the field, it includes the latest developments in CFD, experimental techniques and guidance for the practical estimation of ship propulsive power. It addresses improvements in energy efficiency and reduced emissions, and the introduction of the Energy Efficiency Design Index (EEDI). Descriptions have now been included of pump jets, rim driven propulsors, shape adaptive foils, propeller noise and dynamic positioning. Trial procedures have been updated, and preliminary estimates of power for hydrofoil craft, submarines and AUVs are incorporated. Standard series data for hull resistance and propeller performance are included, enabling practitioners to make ship power predictions based on material and data within the book. Numerous fully worked examples illustrate applications for most ship and small craft types, making this book ideal for practising engineers, naval architects, marine engineers and undergraduate and postgraduate students.

This SpringerBrief focuses on modeling and power evaluation of high-speed craft. The various power prediction methods, a principal design objective for high-speed craft of displacement, semi-displacement, and planing type, are addressed. At the core of the power prediction methods are mathematical models for resistance and propulsion efficiency. The models are based on the experimental data of various high-speed hull and propeller series. The regression analysis and artificial neural network (ANN) methods are used as an extraction tool for this kind of mathematical models. A variety of mathematical models of this type are discussed in the book. Once these mathematical models have been developed and validated, they can be readily programmed into software tools, thereby enabling the parametric analyses required for the optimization of a high-speed craft design. This book provides the foundational reference for these software tools, and their use in the design of high-speed craft. High-speed craft are very different from conventional ships. Current professional literature leaves a gap in the documentation of best design practices for high-speed craft. This book is aimed at naval architects who design and develop various types of high-speed vessels.

This book introduces a holistic approach to ship design and its optimisation for life-cycle operation. It deals with the scientific background of the adopted approach and the associated synthesis model, which follows modern computer aided engineering (CAE) procedures. It integrates techno-economic databases, calculation and multi-objective optimisation modules and s/w tools with a well-established Computer-Aided Design (CAD) platform, along with a Virtual Vessel Framework (VVF), which will allow virtual testing before the building phase of a new vessel. The resulting graphic user interface (GUI) and information exchange systems enable the exploration of the huge design space to a much larger extent and in less time than is currently possible, thus leading to new insights and promising new design alternatives. The book not only covers the various stages of the design of the main ship system, but also addresses relevant major onboard systems/components in terms of life-cycle performance to offer readers a better understanding of suitable outfitting details, which is a key aspect when it comes the outfitting-intensive products of international shipyards. The book disseminates results of the EU funded Horizon 2020 project HOLISHIP.

Neben der Herleitung und Darstellung der fundamentalen Gleichungen enthält dieses Lehrbuch sehr viele Beispiele und Anwendungen, so z.B. eine genaue Diskussion des Flugmechanismus sowie der Wirkung der verschiedenen Klappen an Flügeln, und ist daher auch für Dozenten eine Fundgrube zur anschaulichen Auflockerung der Vorlesung. Neben den beiden üblichen Schwerpunktthemen "Dynamik idealer Fluide" und "Verhalten sehr viskoser Fluide" wird das wichtige Thema "Grenzschichten" besonders behandelt. Ein Anhang über suprafluides Helium - ein Beispiel für ein ideales Fluid - rundet das Stoffgebiet ab.

These proceedings contain the papers presented at the 7th International Symposium on Practical Design of Ships and Mobile Units. The symposium was held at the Congress Centre in The Hague, The Netherlands on 20-25 September, 1998.The overall aim of PRADS conferences is to advance the design of ships and mobile marine structures through the exchange of knowledge and the promotion of discussions on relevant topics in the fields of naval architecture and marine and offshore engineering. Greater international co-operation of this kind can help improve design and production methods and so increase the efficiency, economy and safety of ships and mobile units. The main themes of this symposium are design synthesis, production, ship hydromechanics, ship structures and materials and offshore engineering. Some topics which attracted many papers were design loads, design for ultimate strength, impact of safety and environment, grounding and collision, resistance and flow, seakeeping, fatigue considerations and propulsor and propulsion systems.

Hermann Oberth gilt als einer der bedeutendsten Pioniere der Raketentechnik. Visionär waren nicht nur seine umfassende, akribische Untersuchung und Optimierung aller denkbaren Raketenparamter, sondern auch seine Vorschläge zur Raketeninstrumentierung für bemannte und wissenschaftliche Missionen sowie Ideen für Start- und Testanlagen. Die Neuauflage ermöglicht es, die Realisierung von Oberth's "Traum" nachzuvollziehen und mit der heutigen Raumfahrtrealität abzugleichen. Reprint der 5. Auflage von 1984
