Abstract

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

Abstract

Le coussinet graisseux est une structure indispensable pour l’amortissement des différentes forces qui sont exercées sur le pied du bovin. En effet, l’appareil suspenseur du pied qui est très développé dans d’autres espèces, comme par exemple chez le cheval, l’est beaucoup moins dans l’espèce bovine. Il existe plusieurs situations dans la vie de l’animal au cours desquelles le coussinet graisseux pourra être modifié au niveau de sa conformation et/ou de sa composition. Ces modifications sont le plus souvent pathologiques et engendrent l’apparition de boiteries. La caractérisation des facteurs de risque de modification du coussinet graisseux chez les bovins laitiers ou allaitants semble donc essentielle afin de pouvoir mettre en place des moyens de prévention précoces et efficaces.

Abstract

WIGs (Wing in Ground) are advanced hybrid air cushion crafts and they offer the combination of speed, fuel efficiency, and ride smoothness. WIG rides above the surface like an airplane on a dynamic air cushion that is produced by the vessel’s forward motion. The adoption of WIG has been slow due to the complicated technology issues surrounding the vessel; it is a hybrid vehicle that combines marine and aviation theory, wing theory and air cushion theory, aerodynamic and hydrodynamic theory. "WIG Craft and Ekranoplan: Ground Effect Craft Technology" provides a comprehensive overview of the design, development and building of WIG vessels. Drawing upon years of practical experience and using numerous examples and illustrative applications, Liang Yun, Alan Bliault and Johnny Doo discuss: Basic principles of WIG craft technology State of the art overview of WIG craft technology in the United States, Russia, Germany, China and Australia Material and structural design of WIG craft Lift and propulsion systems of WIG craft WIG Craft and Ekranoplan: Ground Effect Craft Technology will be of interest to naval engineers, aviation engineers, naval architects, and mechanical engineers interested in the development and research of wing in ground (WIG) and high performance marine vehicles.
