Abstract:

A research and advanced developmentprogram on a 30 KW arc-jet thrustor is described herein. An experimental radiation-cooled, hydrogen-propelled thrustor designed under a previous Air Force program had demonstrated a high level of performance with a lifetime greater than 100 hours. The current program, a continued effort at the 30 KW power level, required the attainment of improved performance characteristics eta or 55 at Isp 1000 secs. and a lifetime demonstration of 500 hours. To attain these difficult performance requriements a thrustor having a regeneratively-cooled anodenozzle was designed which maintained as closely as possible the internal geometry which had performed successfully in the previous program. The successful completion of a continuous 500-hour endurance test at the required operating conditions without failure indicates that this 30 KW arc-jet thrustor is indeed as advanced as any other type of electric propulsion system at this time.
