Download or read book Ion-thruster Propellant Utilization written by Harold R. Kaufman and published by . This book was released on 1971 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evaluation and understanding of maximum propellant utilization, with mercury used as the propellant are presented. The primary-electron region in the ion chamber of a bombardment thruster is analyzed at maximum utilization. The results of this analysis, as well as experimental data from a range of ion-chamber configurations, show a nearly constant loss rate for unionized propellant at maximum utilization over a wide range of total propellant flow rate. The discharge loss level of 1000 eV/ion was used as a definition of maximum utilization, but the exact level of this definition has no effect on the qualitative results and little effect on the quantitative results. There are obvious design applications for the results of this investigation, but the results are particularly significant whenever efficient throttled operation is required.

Download or read book Analytic Performance of Two-grid Accelerator Designs for Kaufman Thrusters written by Walter C. Lathem and published by . 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.

This book was released on 1971 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field evaporation of solid metal electrodes has been proposed as an ion source for an electrostatic propulsion device. The chief advantage over existing ion sources is the prospect of 100 percent fuel utilization efficiency. This advantage arises as a result of the elimination of the need for a gaseous precursor state for propellant ionization. The attainment of required high surface field strengths is achieved through field-induced extrusion of the electrode geometry at elevated temperatures. Contributions of both surface and bulk transport mechanisms are taken into account.
