Endurance testing of the STAR additively manufactured resistojet

Matthew Robinson, Dr Angelo Grubisic, Dr Federico Romei and Christopher Ogunlesi Space Propulsion 2018 14/05/18 → 18/05/18 Seville, Spain Introduction The potential of an all-electric spacecraft is enhanced by the possibility of a single integrated propellant supply. A common propellant choice is xenon. This creates new performance demands for a high-temperature xenon resistojet, elevating the hot gas …

Novel non-destructive inspection of the STAR additively manufactured resistojet

Christopher Ogunlesi, Dr Angelo Grubisic, Dr Federico Romei and Matthew Robinson Space Propulsion 2018 14/05/18 → 18/05/18 Seville, Spain Abstract Surrey Satellite Technology Limited (SSTL) has used a low power hot gas system known as a resistojet since 2002, which uses either Butane or Xenon as propellant. This system has flown on 20 spacecraft including the European …
