Download or read book The Effects of Arcjet Operating Condition and Constrictor Geometry on the Plasma Plume written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-13 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of plasma number density and electron temperature were obtained in the plumes of lab arcjet thrusters using electrostatic probes of both spherical and cylindrical geometry. The two arcjet thrusters used had different constrictor and/or nozzle geometries and operated on mixtures of nitrogen, hydrogen, and ammonia to simulate the decomposition products of hydrazine and ammonia. An increase in the measured electron density was observed for both geometries with increasing arc power at a constant mass flow rate and with increasing mass flow rate at a constant arc current. For a given operating condition, the electron number density decreased exponentially off centerline and followed an inverse distance squared relationship along the thrust axis. Typical measured electron temperatures ranged from 0.1 to 0.2 eV. Carney, Lynnette M. and Sankovic, John M. Glenn Research Center RTOP 506-42-31...

Available in PDF, EPUB and Kindle. Book excerpt: A new edition of the authoritative source on hydrazine chemistry In the past century, hydrazine, an important intermediate in the synthesis of countless chemicals with N-N bonds, has grown into a major industrial commodity with a wide range of uses. It is used as a fuel in rocket propulsion, as a boiler feedwater deoxygenating agent, and in the manufacture of foamed plastics, pharmaceuticals, and biodegradable pesticides and herbicides, to name just a few uses. Since the first edition of Hydrazine and Its Derivatives: Preparation, Properties, Applications was published in 1984, there has been considerable development in this field and many new aspects of hydrazine chemistry and applications have evolved. Offering an overview of hydrazines and their industrial applications, this book also provides a compilation of numerous references to the scientific and technical literature arranged in a systematic manner, allowing the reader to find the necessary information by accessing the pages either from the table of contents or the alphabetical subject index. Some other features of the significantly enlarged Second Edition include: Frequent "see also" cross-references/links to other relevant sections of the bookOver 8,400 references, most of which cover the period from 1980 to 1998 Extremely thorough, encyclopedia-style coverage of topics Information to aid in the design of environmentally benign, biodegradable pesticides and more energetic rocket propellants Background information on the adverse effects of pesticide residue in food Hydrazine and Its Derivatives: Preparation, Properties, Applications, Second Edition is the most comprehensive book ever published on hydrazines, and this new edition is indispensable reading material for chemists, toxicologists, environmentalists, propulsion engineers, materials engineers, and satellite builders.
