Emission Characteristics of Passively Fed Electrospray Microthrusters with Propellant Reservoirs
TL;DR: In this article, a miniaturized ionic liquid electrospray thruster for nanosatellite applications is presented, which features an emitter array of 480 emitter tips per square meter.
Proceedings ArticleDOI
NEXT: NASA's Evolutionary Xenon Thruster
Michael J. Patterson,John E. Foster,Thomas W. Haag,Vincent K. Rawlin,George C. Soulas,Robert F. Roman +5 more
TL;DR: The central feature of the NEXT system is an electric propulsion thruster (EPT) that inherits the knowledge gained through the NSTAR thruster that successfully propelled the Deep Space 1 to asteroid Braille and comet Borrelly, while significantly increasing the thruster power level and making improvements in performance parameters associated with NSTAR.
Performance evaluation of the Russian SPT-100 thruster at NASA LeRC
TL;DR: In this article, performance measurements of a Russian flight-model SPT-100 thruster were obtained as part of a comprehensive program to evaluate engineering issues pertinent to integration with Western spacecraft.
Journal ArticleDOI
Recommended Practice for Thrust Measurement in Electric Propulsion Testing
James E. Polk,Anthony Pancotti,Thomas W. Haag,Scott King,Mitchell L. R. Walker,Joseph Blakely,John Ziemer +6 more
TL;DR: The accurate, direct measurement of thrust or impulse is one of the most critical elements of electric thruster characterization, and it is the most difficult measurement to make as mentioned in this paper, and therefore it is difficult to obtain accurate measurements.
