A COMPARISON OF REVERSE-FEED AND POROUS-TUNGSTEN ION ENGINES

Abstract

A comparison of the theoretical performance of reverse-feed and porous-tungsten cesium ion engines is made considering (1) power efficiency, (2) propellant utilization efficiency, (3) current densities, (4) emitter temperature, and (5) charge exchange, at specific-impulse levels of 3000 to 10,000 seconds.
