NASA马歇尔航天中心新近从德国霍夫曼创新集团公司购买了选择性激光熔化设备,准备为J-2X发动机制造金属零件。这些金属零件将在J-2X发动机的年底热试车过程中接受结构试验。J-2X发动机将用作美国航天发射系统(SLS)重型运载
The NASA Marshall Space Center recently purchased selective laser melting equipment from the German company Hoffmann Innovation Group in preparation for the manufacture of metal parts for the J-2X engine. These metal parts will undergo structural tests during the end of the hot J-2X engine test run. The J-2X engine will be used as a heavy lift vehicle for the U.S. space launch system (SLS)
