          First Reported by Andrew McIntosh of Puget Sound Business Journal on Monday September 28, 2020, the United States (U.S.) Federal Aviation Administration (F.A.A.) has officially certified the largest commercial turbojet engine ever developed, according to Pallini (2020). The new General Electric (G.E.) Aviation GE9X engine was specifically developed and built for the new Boeing 777X widebody airline transport category aircraft, according to Pallini (2020). The new GE9X engine will exclusively power the new Boeing 777X aircraft (Pallini, 2020).

The GE9X engine size is described as massive” by Andrew McIntosh (McIntosh, 2020).

“The most advanced technologies and materials: A blend of evolutionary and revolutionary designs will enable the GE9X to be the most fuel-efficient jet engine GE has ever produced on a per-pounds-of-thrust basis. It’s designed to deliver a 10% improved aircraft fuel burn versus the GE90-115B-powered 777-300ER and a 5% improved specific fuel consumption versus any twin-aisle engine available, plus achieve an approximate 10:1 bypass ratio, a 60:1 overall pressure ratio and margin to Stage 5 noise limits,” according to General Electric (2020).

New design features of the GE9X Turbojet engine include sixteen (16) Carbon Fiber Composite fan blades and a compressor with a compression ratio of twenty-seven to 1 (27:1) “the highest ever in aviation,” according to General Electric Aviation (2020).

The Boeing Company and General Electric (G.E.) Aviation said “the GE9X engine is designed to consume 10% less fuel compared to the older GE90-115B engines and 5% better “than any other engine in its class.” The big engines also will help airlines cut smog-causing emissions,” according to McIntosh (2020).

“”It takes the world’s best talent in jet propulsion to create a game-changing product like the GE9X engine,” GE Aviation President and CEO John Slattery said in a statement,” according to McIntosh (2020).” GE9X program General Manager Karl Sheldon said company officials are pleased with the performance of the engine following extensive ground and flight testing by Boeing. Eight GE9X test engines completed just under 5,000 hours and 8,000 cycles to win the required FAA certification, the company said” (McIntosh, 2020). McIntosh (2020) continues ““There is no substitute that can achieve the combination of size, power and fuel efficiency of the GE9X. This engine will deliver unsurpassed value and reliability to our airline customers,” Slattery said.”

GE Aviation said its focus remains on working with Boeing to complete the 777X flight test program and entry into service for airlines, which the Chicago-based jet maker recently delayed until 2022,” according to McIntosh (2020).

The new Boeing 777X has foldable wing tips.
