| is progressive propulsion plus worth it: Fundamentals of Electric Propulsion Dan M. Goebel, Ira Katz, 2008-12-22 Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field. |

| is progressive propulsion plus worth it: Uranium Enrichment and Nuclear Weapon Proliferation Allan S. Krass, Peter Boskma, Boelie Elzen, Wim A. Smit, Stockholm International Peace Research Institute, 2020-11-20 Originally published in 1983, this book presents both the technical and political information necessary to evaluate the emerging threat to world security posed by recent advances in uranium enrichment technology. Uranium enrichment has played a relatively quiet but important role in the history of efforts by a number of nations to acquire nuclear weapons and by a number of others to prevent the proliferation of nuclear weapons. For many years the uranium enrichment industry was dominated by a single method, gaseous diffusion, which was technically complex, extremely capital-intensive, and highly inefficient in its use of energy. As long as this remained true, only the richest and most technically advanced nations could afford to pursue the enrichment route to weapon acquisition. But during the 1970s this situation changed dramatically. Several new and far more accessible enrichment techniques were developed, stimulated largely by the anticipation of a rapidly growing demand for enrichment services by the world-wide nuclear power industry. This proliferation of new techniques, coupled with the subsequent contraction of the commercial market for enriched uranium, has created a situation in which uranium enrichment technology might well become the most important contributor to further nuclear weapon proliferation. Some of the issues addressed in this book are: A technical analysis of the most important enrichment techniques in a form that is relevant to analysis of proliferation risks; A detailed projection of the world demand for uranium enrichment services; A summary and critique of present institutional non-proliferation arrangements in the world enrichment industry, and An identification of the states most likely to pursue the enrichment route to acquisition of nuclear weapons. |

| is progressive propulsion plus worth it: Who Can Hold the Sea James D. Hornfischer, 2022-05-03 A close-up, action-filled narrative about the crucial role the U.S. Navy played in the early years of the Cold War, from the New York Times bestselling author of The Fleet at Flood Tide “A lucid, fast-moving and fitting finale to [Hornfischer’s] career.”—The Wall Street Journal This landmark account of the U.S. Navy in the Cold War, Who Can Hold the Sea combines narrative history with scenes of stirring adventure on—and under—the high seas. In 1945, at the end of World War II, the victorious Navy sends its sailors home and decommissions most of its warships. But this peaceful interlude is short-lived, as Stalin, America’s former ally, makes aggressive moves in Europe and the Far East. Winston Churchill crystallizes the growing Communist threat by declaring the existence of “the Iron Curtain,” and the Truman Doctrine is set up to contain Communism by establishing U.S. military bases throughout the world. Set against this background of increasing Cold War hostility, Who Can Hold the Sea paints the dramatic rise of the Navy’s crucial postwar role in a series of exciting episodes that include the controversial tests of the A-bombs that were dropped on warships at Bikini Island; the invention of sonar and the developing science of undersea warfare; the Navy’s leading part in key battles of the Korean War; the dramatic sinking of the submarine USS Cochino in the Norwegian Sea; the invention of the nuclear submarine and the dangerous, first-ever cruise of the USS Nautilus under the North Pole; and the growth of the modern Navy with technological breakthroughs such as massive aircraft carriers, and cruisers fitted with surface-to-air missiles. As in all of Hornfischer’s works, the events unfold in riveting detail. The story of the Cold War at sea is ultimately the story of America’s victorious contest to protect the free world. |

| is progressive propulsion plus worth it: Companion to Clinical Neurology William Pryse-Phillips, 2009-06-03 This book is designed for the neurologist who (in this day of unusually strict accountability) needs to have at hand an authoritative guide to the diagnostic criteria for all conditions that he or she may be faced with in clinical practice. While originally conceived as a compendium of diagnostic criteria, the author has felt the need to expand the work to include definitions of practically all terms that are used in neurology today. Historical elements are also provided--including entries of important neurologists and neurosurgeons who have impacted the field. The result is an effective representation of the tools of the trade for the neurologist in training and a concise and precise source for the practicing neurologist. The second edition was published in 2003. Since then, advances in the definition of many neurological conditions have been made, all of which have been incorporated in the third edition. There has also been a fine tuning of the definitions and diagnostic criteria of many other conditions. The author has collated over 1300 articles since the last edition in order to update many of the entries. As such, the entries will have the most up-to-date definition of diseases, symptoms, diagnostic tests, and pearls of wisdom. The third edition remains an invaluable guide to the spectrum of neurological practice and with nearly 7,000 references this truly is the bible of neurological terms and conditions. |

| is progressive propulsion plus worth it: Variable Speed Generators Ion Boldea, 2005-11-09 Surveying the technologies used to satisfy the world's demand for open, efficient, and clean electricity, Variable Speed Generators provides an in-depth examination of variable-speed generators for both stand-alone and grid-connected applications. Part of The Electric Generators Handbook, Two-Volume Set, this work offers authoritative, tightly focused treatment of the topologies, steady state and transients modeling, performance, control, design, and testing of stand-alone and grid-connected generators operating at variable speeds. Variable Speed Generators thoroughly covers all types of variable-speed generators currently in progress in distributed generation and renewable energy applications around the world. It delves into the steady state, transients, control, and design of claw-pole rotor synchronous, induction, permanent magnet-assisted synchronous, and switched reluctance starter alternators for hybrid-electric vehicles. It also discusses PM synchronous, transverse-flux PM, and flux-reversal PM generators for low-speed wind and hydro energy conversion as well as linear-motion alternators for residential and spacecraft applications. Numerous design and control examples illustrate the discussion. The promise of renewable, sustainable energy rests on our ability to design innovative power systems that are able to harness energy from a variety of sources. Variable Speed Generators supplies the tools necessary to design, validate, and deploy the right power generation technologies to fulfill tomorrow's complex energy needs. |
