Book Description
This volume presents an original treatment of the influence ofdifferent types of vortex fields on the dynamics of solid bodies. Thisis encountered in many ways: flight dynamics, hydrofoil vehicledynamics, rockets and spacecraft dynamics, and satellite dynamics.The contents are divided into eight chapters. Chapters 1 and 2 aredevoted to a synthesis of phenomenological mathematical models ofobjects, for which the consideration of vortex fields plays a dominantrole in the formulation of those models. Chapter 3 deals with thesolution of sets of integrodifferential equations which arise in theanalysis of the dynamics of complex controlled systems. Chapter 4considers the experimental verification of models and the limits oftheir applicability. Chapter 5 analyses the influence of eddy currentson the stability of electromagnetic levitation systems. Chapter 6considers the influence on spacecraft motion of the vortex motions ofa low-viscous liquid in the vehicle fuel tanks. Chapter 7 presentsexamples of a control law for the air-gap stabilization of a magneticlevitation system. Finally, Chapter 8 deals with the generalmathematical model based on magnetohydrodynamics of asolid-low-viscous electrically conductive ferromagnetic liquid. For mechanical and aerospace engineers whose work involves guidanceand control systems. ... Read more

Product Description
This unique electronic book on CD-ROM has an amazing collection of federal documents and resources on advanced high-speed train technology, including MAGLEV (magnetic levitation) and high-speed ground transportation (HSGT).The Federal Railroad Administration (FRA) notes: Magnetic levitation (Maglev) is an advanced train technology in which magnetic forces lift, propel, and guide a vehicle over a guideway. Utilizing state-of-the-art electric power and control systems, this configuration eliminates contact between vehicle and guideway and permits cruising speeds of up to 300 mph. Because of its high speed, Maglev offers competitive trip-time savings compared to aviation in travel markets up to 600 miles long - an attractive travel option for the 21st century.The Maglev deployment program was created to demonstrate the potential of a commercial Maglev project in the United States. Section 1218 of the "Transportation Equity Act for the 21st Century" created a National Magnetic Levitation Transportation Technology Deployment Program. The program is administered by the Federal Railroad Administration (FRA), a unit of the Department of Transportation. The objective of the program is to demonstrate high speed maglev technology in commercial service through a project of about 40 miles in length, so that it can be considered later in the century for implementation in a longer distance intercity corridor application. Section 1218 provided $55 million in federal funding for pre-construction planning to identify the most promising project through a competitive process. The Federal funds for planning and construction must be matched 1/3 to 2/3 by state, local, or private contributions. To be eligible for Federal construction funding, each project had to demonstrate that operating revenues would exceed operating costs, and total benefits would exceed total costs over a 40-year period. Applications for projects were solicited from states or their designated authorities, and in May 1999 seven projects were selected to participate in a one-year program of preconstruction planning needed to identify the most promising project. Sponsors of the following projects were given planning grants: Los Angeles, CA; Cape Canaveral, FL; Atlanta, GA to Chattanooga, TN; New Orleans, LA; Baltimore, MD to Washington, DC; Las Vegas, NV to Anaheim, CA; and Pittsburgh, PA. Each of the seven projects submitted a Project Description to FRA on June 30, 2000. The Project Descriptions include: projected environmental effects, costs of construction, equipment, and operations and maintenance; estimates of ridership and revenues; an implementation schedule; operating plans; a management plan defining a public/private partnership that will plan, finance, construct and operate the project; and a financial plan. A multi-disciplined selection review committee from the Department of Transportation reviewed the Project Descriptions received from the seven competing projects. The committee reported to the Secretary on the merits of each project, to assist him in selecting the most promising projects to receive continued federal support for the pre-construction planning. The Department of Transportation selected the Maryland and Pennsylvania projects to continue to the next stage of the program. A Final Programmatic Environmental Impact Statement was published and distributed on April 20, 2001 that selected the "action alternative" to continue the program as the preferred alternative, and identified the Maryland and Pennsylvania projects for continued evaluation and project development.Contents include: * MAGLEV Deployment Program * Maglev Projects * Current Project Status * Funding for MAGLEV * MAGLEV Legislation and Regulations * MAGLEV Programmatic EIS * MAGLEV Reports * Passenger Rail / High-Speed Ground Transportation ...
