Ion and hall thrusters
Did you know?
WebAt constant power, Hall thrusters generally have lower specific impulse, efficiency, and total impulse capability (lifetime) than ion thrusters, but have higher thrust-power ratios. ... WebHall thrusters are currently one of the most advanced and efficient types of electrostatic propulsion devices for spacecraft with an efficiency of about 50% [53].In particular, this configuration is beneficial because the acceleration takes place in a quasi-neutral plasma and thus is not limited by space-charge effects.
WebThruster performance was determined using thruster efficiency curves as a function of delivered Isp generated using the general approach presented by Auweter-Kurtz in 2003. 12. These thruster efficiency curves were anchored to engine test data for gridded ion and Hall effect thrusters utilizing xenon, bismuth, and krypton . WebFlight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, …
Web10 nov. 2008 · 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 … WebHowever, the mechanism for transferring the thrust from the ion motion to the thruster body, and thereby the spacecraft, is different for ion thrusters and Hall thrusters. In ion thrusters, ions are produced by a plasma source and accelerated electrostaticly by the field applied between two (or more) grids, as illustrated in Fig. 2-1.
WebIn addition, it overcomes the erosion and lifetime problems that occur in both the Hall Effect thrusters and gridded ion thrusters as there is no contact between the plasma and any electrodes. However, although practical research on this technology has begun, the theory around the existence of a double layer has been much debated on.
