Available in PDF, EPUB and Kindle. Book excerpt: In the early decades of the Space Age, a great deal of work was put into the development of the Colloid Thruster as an electric propulsion system for spacecraft. In spite of the effort by the end of the 70s the programs were stopped in the USA and Europe before any design had gotten to fly in space. An exhaustive study of the literature has been performed to identify what were the reasons behind the disappearance of Colloid Thrusters. Apart from programmatic reasons related to the introduction of the Space Shuttle, some technical reasons where identified. The technical difficulties had to do with the use of arrays of needles. Aiming at overcoming these difficulties, an alternative way to construct Colloid Thrusters has been proposed. Instead of needles, holes in Teflon where used. This has been tested both numerically and experimentally with positive results. This development may be useful not only for colloid propulsion but also for other technologies that require electrospray emission.

Available in PDF, EPUB and Kindle. Book excerpt: Space propulsion systems have a great influence on our ability to travel to other planets or how cheap a satellite can provide TV programs. This book provides an up-to-date overview of all kinds of propulsion systems ranging from classical rocket technology, nuclear propulsion to electric propulsion systems, and further to micro-, propellantless and even breakthrough propulsion, which is a new program under development at NASA. The author shows the limitations of the present concepts and how they could look like in the future. Starting from historical developments, the reader is taken on a journey showing the amazing technology that has been put on hold for decades to be rediscovered in the near future for questions like how we can even reach other stars within a human lifetime. The author is actively involved in advanced propulsion research and contributes with his own experience to many of the presented topics. The book is written for anyone who is interested in how space travel can be revolutionized.

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.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to determine the effect of temperature and composition on alloy softening in group VIA metals Cr, Mo, and W alloyed with Re. Results showed that alloy softening was similar in all three alloy systems occurring at homologous temperatures less than 0.16 and at Re concentrations less than 16 atom percent. Rhenium content required to produce a hardness minimum diminished rapidly in all three systems with increasing test temperature. The similarities in hardness behavior in these three alloy systems suggesat common softening mechanism which may arise from lowering the Peierls stress.

Download or read book Plasma Engineering written by Michael Keidar and published by Academic Press. This book was released on 2013-03-06 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma Engineering is the first textbook that addresses plasma engineering in the aerospace, nanotechnology, and bioengineering fields from a unified standpoint. It covers the fundamentals of plasma physics at a level suitable for an upper level undergraduate or graduate student, and applies the unique properties of plasmas (ionized gases) to improve processes and performance over a wide variety of areas such as materials processing, spacecraft propulsion, and nanofabrication. The book starts by reviewing plasma particle collisions, waves, and instabilities, and proceeds to diagnostic tools, such as planar, spherical, and emissive probes, and the electrostatic analyzer, interferometric technique, and plasma spectroscopy. The physics of different types of electrical discharges are considered, including the classical Townsend mechanism of gas electrical breakdown and the Paschen law. Basic approaches and theoretical methodologies for plasma modeling are described, based on the fluid description of plasma solving numerically magnetohydrodynamic (MHD) equations and the kinetic model particle techniques that take into account kinetic interactions among particles and electromagnetic fields. Readers are then introduced to the widest variety of applications in any text on the market, including space propulsion applications and application of low-temperature plasmas in nanoscience and nanotechnology. The latest original results on cold atmospheric plasma (CAP) applications in medicine are presented. The book includes a large number of worked examples, end of chapter exercises, and historical perspectives. There is also an accompanying plasma simulation software covering the Particle in Cell (PIC) approach, available at http://www.particleincell.com/blog/2011/particle-in-cell-example/. This book is appropriate for grad level courses in Plasma Engineering/Plasma Physics in departments of Aerospace Engineering, Electrical Engineering, and Physics. It will also be useful as an introduction to plasma engineering and its applications for early career researchers and practicing engineers.
