Good development for hight temperature materials 

Rocket engines undoubtedly subject materials to extreme conditions – high temperatures, high pressures, high thermal gradients, high duty cycles, oxidation, propellant compatibility, creep, dynamic loads… safely meeting these demands while minimizing mass can be challenging. The NASA team has been actively maturing the GRX-810 alloy. Glenn Research Center eXtreme alloy (GRX-810) successfully underwent a series of hot-fire tests using LOX/Hydrogen and LOX/Methane propellants. Rigorous high duty cycle testing of various injectors and nozzles demonstrated improved life compared to traditional Nickel-based superalloys. Stress rupture testing revealed an impressive >1,000x improvement, while 1100°C tensile testing indicated a 2x improvement over standard Ni-based superalloys. Our commitment to pushing the boundaries of this alloy continues as we strive towards its commercialization. A recent conference paper highlights some of the hot-fire testing and material characterization: https://lnkd.in/ePtSV_88 The paper will also be available here: https://lnkd.in/dB78ih-p Tim Smith Darren Tinker Christopher Kantzos Ben Williams #rockets #rocketscience #3dprinting #3dprint #additivemanufacturing #nasa #technology #innovation #nasatech #GRX810 NASA - National Aeronautics and Space Administration

CMCs: Enabling Reusable Space Exploration 🚀 👨🚀 How to reduce weight and cost, while increasing safety? The development of reusable launchers has been one of the biggest revolutions in the recent history of space flight. It is not surprising that even now more reusable vehicles are being developed. A lot goes into the design of these vehicles, however, one of the technologies that has especially good synergy with this new class of rockets, is high performance rocket engines, specifically closed cycle engines, with the full flow staged combustion engine being the holy grail. 🔥 However, these engines are complex to produce. One of the main challenges is the high temperatures and pressures in the pre-burners and turbines.  In the early 2000s, NASA - National Aeronautics and Space Administration identified ceramic matrix composites (CMCs) as a potential solution. Doing initial tests of a CMC turbine, NASA concluded that the high temperature limits of CMCs lead to “significantly increased safety, while simultaneously reducing weight and cost”[1]. Recently, European Space Agency - ESA released a tender called THRUST!, encouraging the development of closed cycle engines for their future launchers program. Arceon is preparing to participate in this program with its CMC material, helping with building a new, exciting future, with space more accessible for everyone! ✨ #Innovation #NASA #ESA #ReusableLaunchVehicles #CMCs #MaterialsForExtremes [1] Effinger, Michael R., et al.

📢 Last week, we told you about the WAMS 2024 conference in Orlando. Organized by the European Space Agency - ESA Agency and NASA - National Aeronautics and Space Administration, the symposium, whose title was Shaping the Future of Additive Manufacturing, was a great success with our team on site. To quote our colleague nicolas nutal "Outstanding symposium on metal additive manufacturing with lots of interesting talks and productive discussions" ✔ As a reminder, here are the various conferences held by the CRM Group during the event:  - Postprocessing of additively manufactured components with complex geometries – (Nicolas Nutal) - Development of Al-Zn-Mg alloys for Direct Energy Deposition and repair applications – (Norberto Jimenez Mena) - Development of a New Beta-metastable Titanium Alloy for Additive Manufacturing – (N. Jimenez) A highly successful symposium on space, air and ground transportation technologies! 🚀 #WAMS2024 #AdditiveManufacturing #Innovation #Orlando #CRMGroup #WorldwideAdvancedManufacturingSymposium #ESA #Nasa

We've spent almost 30 years (so far) perfecting our highly controlled burnishing processes. Just a few years after we obtained our first patents for low plasticity burnishing, we wrote this paper with the NASA Glenn Research Center titled, "FOD Resistance and Fatigue Crack Arrest in Low Plasticity Burnished IN718." This paper may be "old," but the research is still relevant and the science is still applied to many applications today. Read the full text to learn how to improve the fatigue and FOD tolerance of superalloy components. Link in comments. #superalloy #NASA #aerospaceengineering
