China3D printingNet December 11th, the National Aeronautics and Space Administration (NASA) announced that it has successfully completed two3D printing23 hot fire tests were carried out on the parts of aero engine (copper alloy combustion chamber and specially developed iron-nickel super alloy nozzle).
Throughout November, these DED-printed components were able to withstand the extreme high temperatures normally encountered by its traditionally manufactured parts during space flight. NASA has high hopes that it classifies additive manufacturing as one of the five industries of the future, which will help make aerospace production faster and more cost-effective than ever.
Tom Teasley, a test engineer at NASA’s Marshall Space Flight Center, said: “In terms of reducing total hardware manufacturing time and costs, this3D printingTechnology will change the rules of the game. These heat tests are a key step in preparing the hardware for future missions to the moon and Mars. “

Why conduct the Heat test?
The heat test is one of the final stages of NASA’s engine test system to ensure that the entire system is operating normally and is ready for takeoff. The test is designed to replicate the launch conditions so that fuel flows through the tank, fuel lines, valves and booster system and ignites.
The 23 Heat tests conducted at the Marshall Space Flight Center took 280 seconds in ten days. NASA engineers were able to collect a large amount of data and measurements, including the pressure and temperature in the main cabin and coolant channels. In addition to giving the team the opportunity to record high-speed video clips of the cabin throat and exhaust plume, these tests can also calculate the overall performance and efficiency of the engine.
The tests performed as part of NASA’s Longevity Additive Manufacturing Assembly (LLAMA) project (part of the “game changer” program led by Marshall) were ultimately designed to make3D printingQualified and can be used to manufacture future lunar landers. Marshall engineers have planned to perform other heat tests to demonstrate3D printingReliability of engine components.
