[SatNews] Aerojet Rocketdyne (NYSE: AJRD) has completed delivery of a green propellant propulsion subsystem that will be used to test a non-toxic fuel on NASA’s future spacecraft, the Green Propellant Infusion Mission (GPIM). The subsystem was delivered to GPIM prime contractor, Ball Aerospace & Technologies Corp., for integration into the Ball-designed Configurable Platform (BCP) 100 spacecraft bus. Scheduled to launch in 2016, the GPIM will provide safer operations and higher performance on future missions.
“GPIM is the culmination of excellent teamwork between NASA, the Air Force, Ball Aerospace and Aerojet Rocketdyne,” said Julie Van Kleeck, vice president of Advanced Space and Launch Programs at Aerojet Rocketdyne. “This propulsion system delivery marks the success of more than 10 years of research and development. Following extensive testing, we ended up with a propulsion design using a new, green monopropellant, which will fly into orbit in 2016. The mission will demonstrate the use of this American-made green propellant for multiple applications—a key objective.”
“This is a critical milestone for the GPIM program that will be a game-changer for how we travel in and through space,” said Jim Oschmann, vice president and general manager of Civil Space and Technology at Ball Aerospace. “This new technology offers longer mission durations, additional maneuverability, increased payload space and simplified launch processing for future spacecraft.”
The green propellant propulsion subsystem, built by Aerojet Rocketdyne in Redmond, Washington, consists of a propellant tank and five 1-newton thrusters to carry the new non-toxic fuel, called AF-M315E. Developed by the Air Force Research Laboratory at Edwards Air Force Base, the new propellant is safer to handle and offers a 50 percent increase in density-Isp, compared to the conventional chemical propulsion systems, such as hydrazine.
AF-M315E burns hotter than hydrazine, requiring new metals to withstand the high temperatures in the thrusters aboard the propulsion system.
The GPIM payload will fly aboard the BCP 100 spacecraft bus, which will provide standard payload interfaces and streamlined procedures for short lead-time and affordable access to space.
GPIM is sponsored by NASA’s Space Technology Mission Directorate. Led by Ball Aerospace, the GPIM team includes Aerojet Rocketdyne of Redmond, Washington; the U.S. Air Force Research Laboratory at Edwards Air Force Base; the Air Force Space and Missile Systems Center at Kirtland Air Force Base, New Mexico; and three NASA field centers: NASA's Glenn Research Center in Ohio, NASA's Kennedy Space Center in Florida, and NASA’s Goddard Space Flight Center in Maryland.
