Aerojet Announces Licensing and Manufacture of Spontaneous Monopropellant Catalyst S-405
Key NASA and aerospace industry representatives recently approved the S-405 for production. NASA provided funding for the license transfer and much of the transition process. Aerojet's Redmond, Washington, facility will manufacture S-405.
"We are very pleased with the outcome of the transition of this production process," said Scott Neish, Aerojet's Redmond Operations vice president and general manager. "The success of the transition illustrates the commitment to stewardship of the product line by the NASA and Aerojet team."
Shell 405 catalyst was developed in the 1960s for use on launch vehicle upper stages and spacecraft. It is used in durable monopropellant hydrazine thruster and gas generators for such applications as the Voyager 1 and Voyager 2 spacecraft (launched in 1977 and still operating). The catalyst is also used on the Space Shuttle gas generators for the Auxiliary Power Units (APUs) and interplanetary probes and landers. Aerojet's long history manufacturing 10,000 flight monopropellant hydrazine thrusters for a variety of applications makes the production of the S-405 a particularly strong complement.
Robert L. Sackheim, assistant director and chief engineer for propulsion at NASA's George C. Marshall Space Flight Center said, "The transition from Shell 405 to S-405 will continue to enable many future spacecraft and launch vehicle missions for space exploration, communications and defense. We have seamlessly moved from Shell 405 to a totally acceptable replacement. We at NASA are pleased to have actively nurtured this program for important future space applications and are pleased with the very capable job and leadership shown by Aerojet."
