万彩网100线路According to the announcement on the GE website on October 12, 2021, the GEnx engine completed over 3000 cycles of vacuum testing in simulated harsh environments using specialized vacuum equipment, achieving excellent durability test results. Dust durability testing is part of GE's ongoing investment in the next-generation technology of its engine series to ensure that the fastest selling high thrust engine in GE's history continues to provide high-quality service to customers in the next decade.

Ten years ago today, the GEnx engine was put into use to power the 747-8 aircraft of Luxembourg Cargo Company. GEnx was developed specifically for the Boeing 787 and 747-8 aircraft, and compared to GE's CF6 engine, it reduces fuel consumption and carbon dioxide emissions by up to 15%.

The dust that may cause hardware damage is very small and cannot be seen by the naked eye. Test engineers use complex equipment, including sensitive sensors to detect dust, and use lean principles to improve test results during testing.
