This book was released on 2018-06-24 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future NASA missions will require high-performance electric propulsion systems. Hall thrusters are being developed at NASA Glenn for high-power, high-specific impulse operation. These thrusters operate at power levels up to 50 kW of power and discharge voltages in excess of 600 V. A parallel effort is being conducted to develop power electronics for these thrusters that push the technology beyond the 5kW state-of-the-art power level. A 10 kW power module was designed to produce an output of 500 V and 20 A from a nominal 100 V input. Resistive load tests revealed efficiencies in excess of 96 percent. Load current share and phase synchronization circuits were designed and tested that will allow connecting multiple modules in parallel to process higher power. Pinero, Luis R. and Bowers, Glen E.

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 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The USAF has identified high-power Electric Propulsion (EP) as an enabling technology for orbital transfer vehicles and re-supply ships. While the path for developing high-power EP systems is somewhat certain given NASA's recent success with its 70+ kW NASA-457M Hall thruster, it is clear that testing 50-kW-class thrusters in current test facilities is of concern given the high facility pressures. In response to this issue, the USAF has embarked on the concept of clustering the use of multiple Hall thrusters in a propulsion array-to allow a single thruster to be ground-tested on behalf of the entire cluster. While clustering is a logical approach to high-power EP, there is no fundamental understanding of how clustered thrusters operate or how one can use single-engine ground-based data to predict the performance, life, or interaction among engines, and the potential spacecraft integration issues associated with clustering. Our program addresses these issues by characterizing the influence of tank pressure on performance and plume characteristics for monolithic and clustered thrusters. We report on our second year studies on clustering, about how chamber pressure influences ion current density distribution, and summarize findings from cold- and hot-flow pressure map data of our vacuum chamber for a number of Hall thruster mass flow rates.

Download or read book "High-Power Hall Devices: Status and Current Challenges." written by and published by . This book was released on 2004 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consideration of the high power electric propulsion (EP) orbit transfer vehicles, interplanetary robotic and manned missions from one side and successful application of Hall thrusters onboard of numerous GEO satellites (Russian EXPRESS and YAMAL series), European scientific mission SMART-I on the other side stimulate interest to high power Hall devices, suitable for the future applications. Current experience for the Hall flight thrusters is limited by 1-kW-class of propulsion systems. At the same time engineering thrusters have demonstrated power level about 25 kW (Fakel Design Bureau, Russia) and almost 100 kW (NASA GRC) with using xenon as a propellant, 150 kW for bismuth thruster (TSNIIMASH, Russia). It is necessary to underline, that principal limits have not been identified for the further increasing of the thruster size and power. This makes the Hall devices at least very competitive for high power application as compared with other types of electric thrusters: MPD and ION thrusters. For high power EP systems two typical operation modes may be considered, namely "high specific impulse (Isp)" and high thrust" modes. Correspondingly challenges to develop Hall EP system are different for each one. For high thrust" mode the development issues associate with increasing of propellant flow and thruster size. Discharge voltage to get "high thrust" regime with best power-to-thrust ratio should be 150.300 V, and it is inside of well studied operation range of Hall thrusters. For "high Isp" mode required discharge voltage in several times than one for flight qualified Hall EP systems, while mass flow does not essentially exceed already achieved level.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a visionary concept for future development of space travel. It describes the enabling technology for future propulsion concepts and demonstrates how mankind will ‘live off the land in space’ in migration from Earth. For the next few millennia at least (barring breakthroughs), the human frontier will include the solar system and the nearest stars. Will it be better to settle the Moon, Mars, or a nearby asteroid and what environments can we expect to find in the vicinity of nearby stars? These are questions that need to be answered if mankind is to migrate into space.
