Available in PDF, EPUB and Kindle. Book excerpt: Rotation symmetric magnetoplasmadynamic thrusters with self induced magnetic fields are investigated at higher current levels in a steady state operation mode. Three thruster development lines are followed: (a) watercooled nozzle type thrusters, (b) partly radiation cooled nozzle type thrusters, and (c) cylindrical watercooled thrusters. The goal to get 1 MW steady state power input could not be reached in the contract period because of two reasons: the heatflux into the nozzle throat of the investigated DT2 thruster got to unacceptable high values, which has to be overcome by a new construction and both for the nozzle type and cylindrical thrusters the cathode raised problems at high current densities: the thorium oxide agglomerates and the cathodes begin to melt out of their inner zones and become destroyed. Keywords: Steady state magnetoplasmadynamic thrusters; Electric propulsion; Cathodes.

This book was released on 2018-06-21 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: High power magnetoplasmadynamic (MPD) thrusters are being developed as cost effective propulsion systems for cargo transport to lunar and Mars bases, crewed missions to Mars and the outer planets, and robotic deep space exploration missions. Electromagnetic MPD thrusters have demonstrated, at the laboratory level, the ability to process megawatts of electrical power while providing significantly higher thrust densities than electrostatic electric propulsion systems. The ability to generate higher thrust densities permits a reduction in the number of thrusters required to perform a given mission, and alleviates the system complexity associated with multiple thruster arrays. The specific impulse of an MPD thruster can be optimized to meet given mission requirements, from a few thousand seconds with heavier gas propellants up to 10,000 seconds with hydrogen propellant. In support of programs envisioned by the NASA Office of Exploration Systems, Glenn Research Center is developing and testing quasi-steady MW-class MPD thrusters as a prelude to steady state high power thruster tests. This paper provides an overview of the GRC high power pulsed thruster test facility, and presents preliminary performance data for a quasi-steady baseline MPD thruster geometry.

Download or read book MPD (Magnetoplasmadynamic) Thruster Advanced Pumping System Concepts written by S. K. Bhattacharyya and published by . This book was released on 1987 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetoplasmadynamic (MPD) thrusters have a number of features that make them attractive for use in several intermediate term missions planned by the U.S. Air Force and Nasa. Theoretical studies and laboratory scale pulsed tests performed to date have established the basic characteristics of MPD thrusters and have provided a basis for optimism regarding their eventual performance. The high (multimegawatt) power sources for space use currently being developed in the Strategic Defense Initiative can be adapted for use with MPD thrusters. Given these conditions, a major requirement for MPD thruster development is the availability of a suitable prototype test facility since successful development of multimegawatt MPD thrusters will depend, to a great extent, on testing them under realistic steady characteristics, life cycle expectancy, electrode erosion rates, and other data essential to the design of working thrusters. The major technical obstacle for ground testing of MPD thrusters in a space simulation facility is the inability of state-of-the-art vacuum systems to provide the tremendous pumping speeds that are required for multimegawatt MPD thrusters. This is true for other types of electric propulsion devices as well. This report discusses the efforts of a first phase or an evaluation of steady state MPD thruster test facilities and addresses the conceptual design of vacuum pumping concepts for this application were evaluated and are reported herein.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Electric Propulsion Understand the fundamental basis of spaceflight with this cutting-edge guide As spacecraft engineering continues to advance, so too do the propulsion methods by which human beings can seek out the stars. Ion thrusters and Hall thrusters have been the subject of considerable innovation in recent years, and spacecraft propulsion has never been more efficient. For professionals within and adjacent to spacecraft engineering, this is critical knowledge that can alter the future of space flight. Fundamentals of Electric Propulsion offers a thorough grounding in electric propulsion for spacecraft, particularly the features and mechanisms underlying Ion and Hall thrusters. Updated in the light of rapidly expanding knowledge, the second edition of this essential guide detailed coverage of thruster principles, plasma physics, and more. It reflects the historic output of the legendary Jet Propulsion Laboratory and promises to continue as a must-own volume for spacecraft engineering professionals. Readers of the second edition of Fundamentals of Electric Propulsion readers will also find: Extensive updates to chapters covering hollow cathodes and Hall thrusters, based on vigorous recent research New sections covering magnetic shielding, cathode plume instabilities, and more Figures and homework problems in each chapter to facilitate learning and retention Fundamentals of Electric Propulsion is an essential work for spacecraft engineers and researchers working in spacecraft propulsion and related fields, as well as graduate students in electric propulsion, aerospace science, and space science courses.
