NASA ‘s renewed efforts to return humans to the moon by 2024 has led to advances in new space technologies to improve processes, and reduce costs and development time.
In early December 2020, we learned that engineers at the U.S. space agency’s Marshall Space Flight Center in Huntsville, Alabama successfully hot-fire tested 3D printed components for rocket engines. The copper alloy combustion chamber and nozzle were made of a high-strength, hydrogen-resistant alloy and could withstand the same extreme combustion environments that traditionally manufactured metal structures experience in flight.
This huge milestone could pave the way for 3D printed parts aboard new rockets.
“This 3D printed technology is a game-changer when it comes to reducing total hardware manufacturing time and cost,” said Thomas Teasley, a test engineer at NASA’s Marshall Center. “These hot-fire tests are a critical step in preparing this hardware for use in future Moon and Mars missions.” Teasley worked with a team of Marshall test engineers to prove how good these 3D printed parts are. For the task, they performed 23 hot-fire tests for a total duration of 280 seconds over 10 test days. Throughout the testing, engineers collected data, including pressure and temperature measurements in hardware […]
