GE9X recognized as most powerful jet engine in the world


The GE9X engine for the Boeing 777X has been recognized by the Guinness Book of World Records as the the most powerful commercial aircraft jet engine (test performance) after reaching 134,300 lbs of thrust.

The record-breaking thrust occurred during an engineering test on November 10, 2017 at GE’s outdoor test facility in Peebles, Ohio. Guinness World Records acknowledged the feat earlier this month at a ceremony at GE Aviation’s Ohio headquarters as part of the company’s 100 year celebration.

The GE9X’s achievement breaks the record held by GE’s GE90-115B engine of 127,900 lbs of thrust, which was set in 2002.

David Joyce, president and CEO  of GE Aviation said, “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.

“While we didn’t set out to break the thrust world record, 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.”

More than 700 GE9X engines are on order with eight customers. The GE9X engine has the largest front fan at 134 inches in diameter, with a composite fan case and 16carbon fiber composite fan blades.

Other key features include: a highly efficient 27:1 pressure-ratio high-pressure compressor; a low emissions  combustor; and lightweight and durable ceramic matrix composite material used in the combustor and turbine.

Last month mechanics from five airlines, Boeing and GE Aviation engineers along with the Federal Aviation Administration took part in an ETOPS (Extended-range Twin-engine Operational Performance Standards) Maintenance Demo at GE Aviation’s Peebles Test Operation, Ohio.

Using the Boeing 777X AMM (Aircraft Maintenance Manual) and a GE9X development engine, the group followed the AMM procedure line-by-line for the removal and installation of GE9X line replaceable components.

The 10-day effort successfully validated the AMM procedures, helping to pave the way for a smooth GE9X entry into service.
