Space and astronomy news
When it comes to the current era of space exploration, one of the most important trends is the way new technologies and processes are lowering the cost of sending crews and payloads to space. Beyond the commercial space sector and the development of retrievable and reusable rockets, space agencies are also finding new ways to make space more accessible and affordable.
Compared to other metals, aluminum has a lower density and can enable high-strength, lightweight components. However, with conventional manufacturing, a rocket nozzle may require a thousand individually joined parts. This makes aluminum impractical since it has a low tolerance to extreme heat and a tendency to crack during welding.
“Industry partnerships with specialty manufacturing vendors aid in advancing the supply base and help make additive manufacturing more accessible for NASA missions and the broader commercial and aerospace industry. This test series marks a significant milestone for the nozzle. After putting the nozzle through the paces of a demanding hot-fire test series, we’ve demonstrated the nozzle can survive the thermal, structural, and pressure loads for a lunar lander scale engine.
