Is GE90 stronger than GE9X?
The GE90 holds the title of the most powerful commercial engine in service, with a maximum thrust of 115,540 lbf (pounds-force). The GE9X, Surpasses this record by generating a whopping 134,000 lbf of thrust, making it the most powerful commercial engine ever tested. The GE9X is the most powerful aircraft engine in history and the quietest GE engine ever produced (pounds of thrust per decibel). The engine will bring up to 10% specific fuel consumption improvement compared to the GE90-115B.
How reliable is the GE9X engine?
Compressor issues delayed the 777-9’s first flight from 2019 to 2020, while a technical issue with a GE9X engine caused the company to pause flight testing in 2022. In 2024, the 777X test fleet was grounded after cracks were found in the aircraft’s thrust links, pausing the program’s flight test campaign until 2025. Beyond internal disruptions, the 777X has had its fair share of technical issues that have had to be resolved before progressing in the certification process. Flight testing has been paused numerous times due to GE9X engine issues, the sole powerplant for the 777X, as well as for other reasons.
Is the GE9X the most powerful engine?
The GE9X is the world’s most powerful commercial jet engine designed to power the Boeing 777X. Yet to enter commercial service, the GE9X holds the Guinness World Record for most thrust ever achieved by a commercial jet engine, having generated 134,300 pounds-force (lbf) of thrust. GE Aviation announced today its GE9X engine has been certified by the U. S. Federal Aviation Administration (FAA) authorities, a key milestone in its journey to power the new twin-engine Boeing 777X family. The FAR (Federal Aviation Regulation) Part 33 certification involved nine test engines.
What is the most powerful GE engine?
The GE9X is the largest and most powerful commercial aircraft engine ever built, incorporating advanced technologies that enable more efficient, quieter flight with fewer emissions. Both manufacturers are at the forefront of aviation technology, with Rolls-Royce excelling in fuel-efficient designs for long-haul operations and GE focusing on performance and thrust with innovation in materials and sustainability.
