This book was released on 2021-11-30 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: The course keeping and manoeuvring requirements for a ship are governed by international maritime law. In assessing and predicting the course keeping and manoeuvring capabilities of the ship, knowledge is required of the rudder forces necessary to keep a course or facilitate a manoeuvre. The second edition of Marine Rudders, Hydrofoils and Control Surfaces includes up-to-date data and rudder design techniques that enable the rudder forces to be estimated, together with any interactions due to the hull and propeller. The new edition describes the design and application of hydrofoils including shape adaptive design, and their applications including hydrofoil craft, yachts, and kite surfing hydrofoils. The professional will also face the need to design control surfaces for motion control, such as roll and pitch, for surface vessels and submersibles, and the book contains the necessary techniques and data to carry out these tasks.This book is for practicing naval architects and marine engineers, small craft designers, yacht designers, hydrodynamicists, undergraduate and postgraduate students of naval architecture, maritime engineering and ship science, and the broader engineering community involved in the development of marine craft that rely on the generation of ‘lift’ such as control engineers and aerodynamicists. Describes techniques for analyzing the performance characteristics of rudders, hydrofoils, and control surfaces Includes extensive design data and worked examples for the analysis of rudder, hydrofoil and control surface performance Provides a detailed examination of the design of hydrofoils

Johnson and published by . This book was released on 1957 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The existing two-dimensional theory for the characteristics of supercavitating hydrofoils operating at zero cavitation number is modified to include the effects of camber, aspect ratio, and depth of submersion. For a comparison with the theory, two aspect-ratio-1 hydrofoils, a flat plate and one with a cambered lower surface, were tested by operating them near the water surface so that their upper surfaces were completely ventilated. The data obtained verified the theory to within 3 percent. Some experimental data are also presented for the models operating at nonzero cavitation number for both air and water-vapor-filled cavities.

Johnson and published by . This book was released on 1957 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Two new low-drag hydrofoils for operation at zero cavitation number are derived by the application of the Tulin-Burkart linearized theory. The two-dimensional lift-drag ratios of these two hydrofoils operating at design angle of attack are shown to be, theoretically, about 45 and 80 percent greater than the Tulin-Burkart configuration. A simplified calculation of the location of the upper cavity streamline for arbitrary configurations is also presented.

Book excerpt: This very complete book includes more than 270 illustrations, charts, and tables on the subject of creating hydrofoil boats. Because hydrofoils fly like airplanes, except in a denser fluid, the book's subject could be described as aerodynamics adapted to hydrofoils.

Available in PDF, EPUB and Kindle. Book excerpt: In the last half-century, high-speed water transportation has developed rapidly. Novel high-performance marine vehicles, such as the air cushion vehicle (ACV), surface effect ship (SES), high-speed monohull craft (MHC), catamaran (CAT), hydrofoil craft (HYC), wave-piercing craft (WPC) and small water area twin hull craft (SWATH) have all developed as concepts, achieving varying degrees of commercial and military success. Prototype ACV and SES have achieved speeds of 100 knots in at calm con- tions; however, the normal cruising speed for commercial operations has remained around 35–50 knots. This is partly due to increased drag in an average coastal s- way where such craft operate services and partly due to limitations of the propulsion systems for such craft. Water jets and water propellers face limitations due to c- itation at high speed, for example. SWATH are designed for reduced motions in a seaway, but the hull form is not a low drag form suitable for high-speed operation. So that seems to lead to a problem – maintain water contact and either water propulsion systems run out of power or craft motions and speed loss are a problem in higher seastates. The only way to higher speed would appear to be to disconnect completely from the water surface. You, the reader, might respond with a question about racing hydroplanes, which manage speeds of above 200 kph. Yes, true, but the power-to-weight ratio is extremely high on such racing machines and not economic if translated into a useful commercial vessel.

This book was released on 2020-12-29 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine propulsors are key components of the many thousands of ships and boats operating in oceans, lakes, and rivers around the world. The performance of propulsors are important for the environmental impact of ships, underwater noise impact on aquatic fauna, and crew and passenger comfort and safety. This book presents nineteen papers devoted to the hydrodynamics of different types of marine propulsors (conventional propellers, thrusters, and novel solutions). Most of the papers are extended papers from the sixth International Symposium on Marine Propulsors (SMP 2019). Several of the papers deal with cavitation, vortices, and energy saving devices. The papers present high-quality research performed using Computational Fluid Dynamics (CFD) and Experimental Fluid Dynamics (EFD) as well Artificial Intelligence (AI).
