Theory and Design of Air Cushion Craft


Book Description

This definitive text describes the theory and design both of Air Cushion Vehicles (ACV) and Surface Effect Ships (SES). It begins by introducing hovercraft types and their development and application throughout the world in the last three decades, before going on to discuss the theoretical aspects of ACV and SES craft covering their hovering performance, dynamic trim over calm water, resistance, stability, manoeuvrability, skirt configuration and analysis of forces acting on the skirts, ACV and SES seakeeping, and the methodology of scaling aerodynamic and hydrodynamic forces acting on the ACV/SES from model test data. The latter chapters describe a design methodology, including design criteria and standard methods for estimating craft performance, lift system design, skirt design, hull structure, propulsion systems and power unit selection. Much technical information, data, and references to further work on hovercraft and SES design is provided. The book will be a useful reference to engineers, technicians, teachers, students (both undergraduate and postgraduate), operators etc. who are involved in ACV/SES research, design, construction and operation. - Guides the reader on how to perform machinery and systems selection within ACV and SES overall design - For teachers, students (both at under- and post-graduate level), engineers and technicians involved in ACV/SES




Hovercraft Technology, Economics and Applications


Book Description

The amphibious versatility, marine speed and low footprint pressure have given the hovercraft a role in specialized applications. Among them are search and rescue, emergency medical services, military and arctic operations, icebreaking, patrol, law enforcement, ferries, and recreational activities such as racing. To meet these demands, the hovercraft has undergone considerable development since its inception. A comprehensive and timely review of the analysis, design, operation, economics and applications of hovercraft is presented in this volume by a team of highly qualified experts. The topics covered range from first principles to the state-of-the-art, with extensive references to current literature. The overall presentation is intended not to exceed the final year level of undergraduate engineering. The introduction and summary sections of all chapters are intended to give a qualitative grasp of the material covered without having to read all the technical portions.In varying degrees, the volume will appeal to managers, decision-support staff, operators, technologists, undergraduate students, and anyone entering the hovercraft field or seeking an introduction to it. It will also be of interest to design engineers, researchers and graduate students. Thus, this volume can serve as an up-to-date reference on several important aspects of hovercraft for a wide range of readers.




National Transportation Planning


Book Description

Soon after starting work on the development of a methodology for national trans portation planning in Venezuela, we realized the importance of an integrated management process for such an effort. We also realized the absence in the literature of specific guidelines on how to manage and conduct a transportation planning effort. The literature on the subject of national transportation planning is predominantly theoretical and technical in nature. To a large extent, the absence of literature on management and broad-based methodological approaches reflects the limited and ad hoc nature of the experience in national transportation planning. This book is an attempt to fill that gap. The main objective of the book is to show one way by which a methodology for national transportation planning can be integrated into a process management framework. It reports on the experience that the authors had in the Venezuelan case, as well as in earlier national planning efforts. The book is not intended as a theoretical discussion of planning. Instead, it adopts a particular theoretical stand and proceeds on that basis to develop a program for applying a specific methodology. The intention is to leave as much of the details and elaborations of that methodology to the user. This is motivated by two considerations. The first is a pragmatic attempt to limit the scope of the book.
