GE Honda Aero Engines said it is releasing hardware designs and receiving manufactured hardware for its first HF120 development engine, in preparation for formal certification testing. To date, the company has built and tested 10 HF120 engine cores and 10 full engine demonstrators. During demonstration testing at Honda’s WAKO-Nishi R&D Center in Japan, the HF120 produced more than 2,100 pounds of thrust and exceeded its fuel-efficiency target. The tests also verified the engine design’s operability and thermal, mechanical and component efficiencies, according to GE Honda.
