Aerojoet Rocketdyne (AR), a US space agency and California-based rocket and missile propulsion manufacturer in collaboration with NASA invented 3-D manufactured copper parts that has the ability to defy the heat and pressure required at the time of space launch. According to sources, the team has also successfully tested an advance rocket engine’s chamber and four injectors assembled with copper alloys on a hot fire at NASA’s Glenn Research Center.
“This time NASA really did hard work to perform 19 rigorous tests and confirmed that it’s new invention of 3-D copper parts could actually withstand the heat and pressure necessary at the time of launch,” said NASA in a journal.
Tyler Hickman an engineer at Glenn shared his experience during the test with our journalist and said that the success in the hot-fire test of engines helped them in building confidence in manufacturing process “The successful hot-fire test of engine components provides confidence in the additive manufacturing process and paves the way for full-scale development.”
The modernization in space technology has made many alterations in speed, cost and flexibility in designing and developing of future space machines. NASA said in a statement that it is a significant invention for development. “The work is a significant milestone in the development and certification of different materials used in this manufacturing process.”
As per Aerojoet Rocketdyne (AR) the micro-structure and characteristics may be low as compared to typical copper as copper alloys generates more unique challenges for the manufacturing process. So to minimize this, many brains performed various rigorous tests so as to know how the alloy performs structurally.
“Additively manufactured metal propulsion components are truly a paradigm shift for the aerospace industry,” Glenn project manager, Paul Senick shared with media.
However, at last Senick remarked that NASA with the help of its industrial partners is on their way to invest in the invention so as to improve the efficiency and to lower down the expenses. “NASA and its commercial partners continue to invest in additive manufacturing technologies, which will improve efficiency and bring down the cost of space launches and other earth applications,” stated Paul Senick.
