Boeing 777X’s GE9X engine broke the Guinness World Records title for thrust to be the most powerful commercial aircraft jet engine (test performance) on reaching 134,300 pounds. The last record was set by GE90-11B engine of 127,900 pounds in 2002.
The thrust actually occurred during an engineering test on November 10, 2017 at the outdoor test facility of GE ay Peebles, Ohio but Guinness World Records acknowledged the feat on July 12, 2019 at a ceremony at Ohio headquarters of GE Aviation as part of the 100th year celebration of the company.
“The GE9X engine incorporates the most advanced technologies that GE Aviation has developed during the last decade and is the culmination of our commercial engine portfolio renewal,” said David Joyce, president and chief executive officer of GEE Aviation. “While we didn’t set out to break the thrust GUINNESS WORLD RECORDS title, we are proud of the engine’s performance, which is a testament to our talented employees and partners who design and build outstanding products for our customers.”
The GE9X engine is in the 100,000 pound thrust class and has the largest front fan at 134 inches in diameter with a composite fan case and 16 fourth-generation carbon fiber composite fan blades. A highly efficient 27:1 pressure-ratio high-pressure compressor, a third-generation low emissions TAPS III combustor, and a lightweight and durable ceramic matrix composite material in the combustor and turbine are some of the other key features of the engine. As many as eight customers have already ordered more than 700 GE9x engines as of now. The certification testing of the engine is still in progress and should be completed by this year.
The participants in the program of GE9X engine are IHI Corporation, Safran Aircraft Engines, Safran Aero Boosters and MTU Aero Engines AG.
