Available in PDF, EPUB and Kindle. Book excerpt: The development of a 30 KW electrothermal (arc-jet) engine for space propulsion is described. An experimental 30 KW DC thruster was redesigned to increase life and decrease propellant leakage while maintaining the high level of performance (I sub sp = 1000 sec.; eta> or = 50%) obtained during that research program. Concurrently, other components of the engine, including a hydrogen propellant storage and feed unit, starter and engine controls, and mounting structure were designed, procured or fabricated, and assembled as a demonstration engine. The major accomplishments during this program were (1) operation of a thruster at a nominal specific impulse of 1000 seconds for twenty-five hours with negligible erosion; (2) development of a cryogenic hydrogen propellant storage and feed unit and engine controls suitable for unattended engine stand-by and operation; and (3) demonstration of a high level of thruster performance (efficiency values above 50 percent at a specific impulse of 1000 seconds) in a flight-type thruster. This type of engine is now ready for an advanced development phase, which is necessary to insure the reliability of such a propulsion device during prospective space missions. (Author).

Download or read book Electric Propulsion Development written by Ernst Stuhlinger and published by Elsevier. This book was released on 1963-01-01 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in Astronautics and Aeronautics, Volume 9: Electric Propulsion Development covers the proceedings of the Second Electric Propulsion Conference of the American Rocker Society, held in Berkeley, California on March 14-16, 1962. The conference focuses on the existing problems in electric propulsion and their possible solutions. This book is organized into four sections encompassing 35 chapters. The first section deals with the thermodynamics of arcs; the problems of heat and momentum transfer; the chemical processes within arcs; the arc system materials; and the arc jet design problems. The second section considers the problems of ion systems, the various ion sources, and the neutralization of ion beams. This section also looks into the basic ionization processes, the production and charging of heavy particles, the corrosive properties of cesium, and the ion-optical designs. The third section describes various plasma systems, including helical transmission lines, pulsed pinch accelerators, coaxial systems, and j x B accelerators. The theoretical analyses of these systems are briefly examined. The fourth section includes papers on flight testing of electric propulsion models, on vertical rocket probes, and on satellites, This section also discusses some advanced concepts in electric propulsion, such as air scooping during ascent through the atmosphere, systems design and optimization, and planetary and interplanetary missions. This book is of great value to physicists, space engineers and designers, as well as researchers in the fields of astronautics and aeronautics.

Download or read book Thermal Spray Fundamentals written by Maher I. Boulos and published by Springer Nature. This book was released on 2021-10-19 with total page 1147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully revised, industry-standard resource offers practical details on every aspect of the fundamentals necessary for understanding thermal spray technology, from powder all the way to the final part. The second edition is presented in a reader-friendly format that is split into four parts. Part I presents a review of thermal spray coating and its position in the broad field of surface modification technologies. Highlights of combustion and thermal plasmas are given with an expanded treatment of in-flight plasma-particle interactions. The second and third parts deal respectively with an updated presentation of thermal spray technologies and coating formation, including solution and suspension plasma spraying. The last part of the book includes a comparative analysis of different thermal spray processes, which is essential for the optimal selection of the appropriate thermal spray process in a given application. Coverage of system integration has been expanded with the addition of a detailed discussion of online instrumentation and process diagnostics and numerous examples of industrial scale spray booth designs. Attention is also given to coating finishing and health and safety issues. An extensive review is presented of thermal spray applications grouped in terms of process objectives and present use in different industrial sectors. This book will serve as an invaluable resource as a textbook for graduate courses in the field and as an exhaustive reference for professionals involved in the thermal spray field.
