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

A technical summary is given of the development of air cushion craft from their inception to the present day. The designation "air cushion craft" encompasses any craft that relies on a cushion of air for a significant part of its support and operates in close proximity to the suface. The technical summary covers both aerostatic craft known as air cushion vehicles (ACV) and surface effect ships (SES) as well as aerodynamic craft such as wing-in-ground effect vehicles (WIG). Other variants are included in the review.

This report presents a survey of the present state of technology as well as practical experiences relating to design and operation of air-cushion vehicles (ACV's). Topics include a brief description of vehicle types and basic-engineering principles, characteristics of existing vehicles and those of the near future, existing and potential main machinery and propulsion systems, and possible technological trends in critical areas. No attempt is made to discuss the potential of ACV's for naval application; rather, the technologic base is identified so as to make available to naval architects information supplemental to their conceptual design studies. On the basis of available information one can conclude that air-cushion vehicles of 1,000 tons and larger will not be available for open ocean operations within the next 2 to 3 years. (Author).

A model of an air cushion vehicle (ACV) with a deep pericell-type skirt and high cushion loading has undergone experiments in calm water and head random waves. The main goal of the investigation was to obtain drag and motion data which can be used to guide the design of a prototype. The results will also be used to validate computer predictions. Plots of mean drag are presented in this report, as are tables containing standard deviation values of motions and accelerations. The effect of model weight and volume air flow on drag and motions is discussed. It is also shown that this heavily loaded ACV has higher hump and post-hump drag than a similiarly configured ACV with smaller payload and shorter skirt. In addition, the heavier, deep-skirted vehicle pitches less and heaves about the same as the other craft. (Author).
