High Specific Impulse Thermal Arc Jet Thrustor Technology
Abstract
A thrustor was tested in a high vacuum (.0000001 torr) with lithium as a propellant, an identical thrustor was evaluated with potassium as the propellant with a wide variation of operating parameters, and improvements were made to the alkali metal feed system and the thrust measurement system. The high-vacuum tests essentially duplicated the performance of the lithium thrustor (Isp = 5000 sec, eta sub T = 53%) measured at the higher pressure of .001 torr during a 10-hour endurance test. The efficiency and maximum specific impulse of the thrustor with potassium were lower than with lithium.
