  • Development of a Hydrazine Arcjet System Operating at 100 Volts Input Voltage
    International Electric Propulsion Conference, October 2017, Atlanta, Georgia IEPC 2017-305 Development of a Hydrazine Arcjet System Operating at 100 Volts Input Voltage Dieter M. Zube1, Keith D. Goodfellow2, Chris Hearn3 Aerojet Rocketdyne Inc., Redmond, WA 98052, U.S.A. Abstract Since 1996, Aerojet Rocketdyne MR-510 hydrazine arcjet systems have provided North-South station keeping for more than 44 geostationary spacecraft. A typical system consists of four 2 kW arcjets, two of which can be operated simultaneously from a Power Conversion Unit (PCU) that includes three power converters in a three for two redundant arrangement. Over the last two years, the flexibility of the system was expanded by developing and qualifying a modern state of the art PCU for a 100 VDC spacecraft power bus. To set the stage, the paper summarizes the development and deployment history of hydrazine arcjet systems beginning in 1993. It discusses the changes and repeated system life tests which significantly expanded the flexibility and robustness of the arcjet system. The paper then describes the changes necessary to accommodate the new PCU with an input voltage of 100 VDC and a new communication protocol. While there were only a limited number of changes required for the thruster and its subcomponents, the PCU underwent a complete redesign. Aerojet Rocketdyne incorporated advances in design philosophy, electronic components, and materials to avoid component obsolescence while improving overall system reliability. 1. Hydrazine Arcjet System History propulsion systems was dormant until a Electric propulsion (EP) systems are usually development effort initiated by NASA and grouped by their primary acceleration industry in the early 1990s put hydrazine arcjets mechanism (electrothermal, electrostatic, and on the GE-Astro (now Lockheed Martin) Series electromagnetic), and there are six classical EP 7000 spacecraft bus in the form of the Aerojet thruster types: resistojets, arcjets, ion thrusters, Rocketdyne MR-508/509 hydrazine arcjet Hall current thrusters, Pulsed Plasma Thrusters system.

The ability for payloads to achieve their target orbits or destinations can still be difficult and potentially not feasible with on-board propulsion limitations. The High Power Solar Electric Propulsion (HP-SEP) Orbital Maneuvering Vehicle (OMV) provides transfer capabilities for both large and small payload in excess of what is possible with chemical propulsion. Leveraging existing secondary payload adapter technology like the ESPA provides a platform to support Multi-Payload launch and missions. When coupled with HP-SEP, meaning greater than 30 kW system power, very large delta-V maneuvers can be accomplished. The HP-SEP OMV concept is designed to perform a Low Earth Orbit to Geosynchronous Orbit (LEO- GEO) transfer of up to six payloads each with 300 kg mass. The OMV has enough capability to perform this 6 km/s maneuver and have residual capacity to extend an additional transfer from GEO to Lunar orbit. This high delta-V capability is achieved using state of the art 12.5 kW Hall Effect Thrusters (HET) coupled with high power “roll up” solar arrays.

Andrew Hoskins* and R. Joseph Cassady† Aerojet Rocketdyne, Arlington, VA, 22209, USA and Olwen Morgan,‡ Roger M. Myers,§ Fred Wilson,¶ David Q. King# and Kristi deGrys** Aerojet Rocketdyne, Redmond, WA, 98052, USA Abstract: Flight experience for Electric Propulsion (EP) supplied by Aerojet since the first launch of Aerojet’s Electrothermal Hydrazine Thruster in 1983 is reviewed. In total, over 210 spacecraft have flown one of four different EP technologies provided by Aerojet: resistojets, arcjet systems, a pulsed plasma thruster system, and Hall thruster systems. The flight systems include over 100 power processing units of seven different designs and over 500 individual thrusters, as well as propellant management hardware. The development history and basic characteristics of each flight system are reviewed. This survey discusses the application of Aerojet’s flight systems in the context of the historical use of electric propulsion flight programs worldwide. Roughly two-thirds of all currently operational spacecraft with EP are flying Aerojet electric propulsion. The usage of total spacecraft flying EP and user type by year is traced. Additionally, trends in the major characteristics of EP bearing spacecraft, such as orbit, mass and power, are discussed. Finally, future developments in electric propulsion
