This book was released on 1971 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented for a theoretical analysis of the performance of two-grid accelerator systems for Kaufman thrusters. Six configurations were used to cover the range of geometries which are of immediate interest. A digital ccomputer program was used to find axially symetric solutions for a single hole of each configuration. Results are presented in terms of maximum current per hole, thrust per hole (including beam divergence effects), and maximum net-to total-voltage ratio consistent with the prevention of electron backstreaming. The results presented herein should be useful in the design of accelerator systems for a variety of applications. An analysis of the effects of charge-exchange ions on the erosion rate of the accelerator grid resulted in equations which could be used to predict the expected useful lifetime of the grid. The equations seemed consistent when theoretical results were compared with experimental results for the SERT II configuration. However, when applied to the configurations used in this analysis, limitations in the usefulness of the model were found and are presented herein.

Download or read book Fundamentals of Electric Propulsion written by Dan M. Goebel and published by John Wiley & Sons. This book was released on 2008-12-22 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
