On October 18, 2026, a successful ignition was achieved in Chicheng, Hebei, with the engine smoothly entering idle operating conditions: 17 categories of core components, including the igniter housing, combustion chamber, and integrated intake duct, were all additively manufactured in a single pass using Chuangrui Laser's self-developed CR-S420 four-laser metal additive manufacturing equipment (with subsequent plans for larger CR-S850/S1300/S1500 models, covering aero-power applications from small and medium-sized components to ultra-large integrated structures). A total of 15 test runs were conducted over 90 minutes, with rotational speeds of 13,920–28,680 rpm and combustion chamber temperatures of 821–998°C, involving three material categories: nickel-based superalloys, aluminum alloys, and stainless steel. This marks a milestone in the transition of fully additively manufactured aero engines from component-level validation to full-engine-level validation, and has direct significance for driving the consumption of superalloy powders in aero-power applications.
