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.

Download or read book Living Off the Land in Space written by C Bangs and published by Springer Science & Business Media. This book was released on 2007-08-24 with total page 250 pages. 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.

Book excerpt: Three different types of sub kilowatt class Hail thrusters tor on-board propulsion of small to mid size satellites are being developed at Busek. This paper describes their performance focusing on plasma behavior outside of the thrusters end contrasts the typical Hail thruster plasma with that encountered in MHD generators end accelerators researched in the past and familiar to the plasmadynamic community. A simple performance predicting analytical model. applicable to all sizes of thrusters also is presented. It adequately matches the measured thrust and specific impulse expressed in terms of primary electron loss parameter, and an overall voltage loss which includes the loss in the plasma bridge between the external cathode and the thruster. The external plasma plume was surveyed using a Faraday cup and an emissive probe to measure the beam current and the plasma potential. These measurements. together with the model support our visual observation that the plume. of a well performing thruster. forms at its center a highly conductive jet with sharply defined cone shaped boundaries. These boundaries were tentatively identified as an ion acoustic shock. The preliminary data and analysis indicate that the plasma downstream of the ion acoustic shock is at least partially responsible for the widely reported correlation between increasing test tank pressure and an increase in performance of Hall thrusters.
