Book Synopsis Fundamentals of Electric Propulsion by : Dan M. Goebel
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.

This book was released on 2018-06-15 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a need for a lightweight, low power ion thruster for space science missions. Such an ion thruster is under development at NASA Glenn Research Center. In an effort to better understand the discharge performance of this thruster. a version of this thruster with an anode containing electrically isolated electrodes at the cusps was fabricated and tested. Discharge characteristics of this ring cusp ion thruster were measured without ion beam extraction. Discharge current was measured at collection electrodes located at the cusps and at the anode body itself. Discharge performance and plasma properties were measured as a function of discharge power, which was varied between 20 and 50 W. It was found that ion production costs decreased by as much as 20 percent when the two most downstream cusp electrodes were allowed to float. Floating the electrodes did not give rise to a significant increase in discharge power even though the plasma density increased markedly. The improved performance is attributed to enhanced electron containment. Foster, John E. and Patterson, Michael J. Glenn Research Center NASA/TM-1999-209386, E-11813, NAS 1.15:209386

Book Synopsis Miniature Ion Thruster Characterization Via Discharge Plasma, Plume, and Mission Analyses by : Stephen Anthony Samples

This book was released on 2021 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Miniature Xenon Ion (MiXI) thruster is a 3 cm DC ion thruster developed as low-power, high effciency micro-propulsion. This work focuses on the further development of the MiXI thruster into a viable propulsion technology and investigates the capabilities of MiXI as primary propulsion on CubeSat missions. First, we set the stage for this work by investigating the viability of high dV small spacecraft missions with high effciency, high impulse propulsion, and explore the sensitivities of mission capabilities to thruster properties and performance. One important conclusion is that in the CubeSat form-factor, high impulse micropropulsion enables high dV missions of several km/s with payloads of multiple U volume and multiple kg mass, however these parameters are very sensitive to thruster parameters such as Isp, total effciency, and neutralizer cathode performance. An ion thruster model is then developed to investigate key aspects of miniature DC ion thruster discharge and thruster performance using simplifed descriptions of the plasma behavior to explore a wide range of the thruster design space. Results from this model provide clear boundaries to miniature ion thruster performance while also providing clear pathways for effectively improving thruster design for increased mission capabilities. The results from the model guide an experimental effort to experimentally investigate the 3-ring and Axial Ring-Cusp Hybrid (ARCH) discharge designs for the MiXI thruster. A small plume diagnostics suite consisting of Faraday, emissive, and ExB probes was developed and used to probe the MiXI(ARCH) plume. While no doubly charged ions were detected in the beam at the operating point measured, measurements agree with prior computational work and show a beam flatness of0.6, divergence of 5 degrees, and plume potential of 4.5 V. Later, MiXI(ARCH) was operated with a miniature discharge hollow cathode. Finally, using lessons learned from cathode integration, computational, and analytical modeling, a refned miniature hollow cathode design was developed to further improve discharge and thruster effciency. Through experimental and analytical investigation, mission studies, and further development of critical aspects of the thruster, this work shows that the MiXI thruster is an attractive propulsion option for high effciency, high specifc impulse micropropulsion.
