Aerojet Rocketdyne Successfully Tests Thrust Chamber Assembly Using Copper Alloy Additive Manufacturing Technology

SACRAMENTO, Calif., Oct. 17, 2014 (GLOBE NEWSWIRE) — NASA and Aerojet Rocketdyne, a GenCorp (NYSE:GY) company, successfully completed a series of hot-fire tests on an advanced rocket engine Thrust Chamber Assembly (TCA) using copper alloy additive manufacturing technology. This testing, conducted for the first time in the industry, was done with cooperation between Aerojet Rocketdyne, NASA’s Space Technology Mission Directorate Game-Changing Development Program and NASA’sGlenn Research Center under a Space Act Agreement.

“This work represents another major milestone in the integrated development and certification of the materials characterization, manufacturing processes, analysis and design-tool technologies that are required to successfully implement Selective Laser Melting for critical rocket engine components,” said Jay Littles, director of Advanced Launch Programs at Aerojet Rocketdyne. “Aerojet Rocketdyne continues to expand the development of novel material and design solutions made possible through additive manufacturing, which will result in more efficient engines at lower costs. We are working a range of additive manufacturing implementation paths – from affordability and performance enhancement to legacy products such as the RL10 upper stage engine. We also are applying the technology to next-generation propulsion systems, including the Bantam Engine family, as well as our new large, high performance booster engine, the AR1.”
