General Electric Built The GE9X So Powerful That It Set A World Record For Jet Engine Thrust

The GE9X, developed by GE Aerospace, set a peak thrust record during an engineering red-line test at GE’s outdoor facility in Peebles, Ohio. The test demonstrated the engine’s capability at 134,300 pounds-force (597.4 kilonewtons).

Guinness World Records recognized the milestone in July 2019, marking the GE9X as the most powerful commercial jet engine ever constructed. The previous record, held by GE’s GE90-115B, stood for 17 years with 127,900 pounds-force (568.9 kilonewtons).

Despite the record thrust achieved in testing, the GE9X’s rated takeoff thrust for airline service is lower. It is certified to fly at a baseline takeoff thrust of 110,000 pounds-force (489.3 kilonewtons).

This lower rating is in comparison to the GE9X’s peak test output and to the thrust of the Boeing 777-300ER, which is exceeded by the GE9X’s peak during testing but not in operational service. When deployed on the Boeing 777X, the propulsion units operate at the lower baseline thrust.

The article notes that the aircraft family planning for this propulsion, the Boeing 777X, will use engines capped at the 110,000 pounds-force baseline, aligning with typical service requirements rather than peak test capability.

The source material frames the achievement within a broader context of record-setting engineering while clarifying the distinction between test performance and in-service thrust ratings.
