Hydrodynamics of High-Speed Marine Vehicles

Hydrodynamics of High-Speed Marine Vehicles discusses hydrodynamic aspects of the three main categories of high-speed marine vehicles, i. e. vessels supported by either the submerged hull, an air cushion or foils. Submerged-hull-supported vessels include planing and semi-displacement vessels. The wave environment, resistance, propulsion, seakeeping, sea loads and maneuvering are extensively covered based on rational and simplified methods. Links to automatic control and structural mechanics are emphasized. A detailed description of waterjet propulsion is given, and the effect of water depth on wash, resistance, sinkage and trim is discussed. Chapter topics include resistance and wash, slamming, air-cushion supported vessels including a detailed discussion of wave-excited resonant oscillations in the air cushion, and hydrofoil vessels including practical aspects as well as foil theory. The book contains many illustrations, examples and exercises. Knowledge about the water flow is important in the structural design and is essential in the construction of an automatic motion control system.
