Design and Development of the MR-510 Arcjet Power Conditioning Unit.

摘要

PRIMEX Aerospace Company's MR-510 hydrazine arcjet system has been successfully flight qualified for use on Lockheed Martin Corporation's A2100 (trademark) communication satellite bus and is currently flying on six spacecraft. The MR-510 arcjet power conditioning unit (PCU) is a key element of this system. It provides the required high voltage start pulse and conditioned power to four 2 kW arcjet thrusters (operated two at a time) for north/south station keeping orbit maneuvers. The PCU draw up to a 4.4 kW of power from the satellite's power bus and provides the command and telemetry interface utilizing a bi-directional serial data bus.
