Aerojet Rocketdyne & NASA Successfully Test 3D Printed Rocket Injector
(AerojetRocketdyne) Aerojet Rocketdyne and NASA successfully completed a series of hot-fire tests on a liquid-oxygen/gaseous hydrogen rocket injector assembly built using additive manufacturing technology. This is a significant advancement in the application of additive manufacturing to rocket engines. This testing, in cooperation with NASA Glenn Research Center (NASA-GRC) under a Space Act Agreement, was a key step in the development and certification of the integrated manufacturing process, analysis and design tool, and component technologies required to implement Selective Laser Melting (SLM) for highly critical rocket engine components. Aerojet Rocketdyne is a GenCorp (NYSE:GY) company.
“This project combined new additive design / analysis tools and manufacturing processes to make a component with legacy engine performance characteristics, paving the road to implement these technologies in these engine products,” said Jeff Haynes, program manager, Additive Manufacturing, Aerojet Rocketdyne.
