Have you ever wondered how big the engines are while boarding an aircraft? Ever imagined yourself standing inside the engine as if it was a miniature room or car? Well, jet engines are quite the hefty big beasts as they should be able to generate enough thrust in order to lift up those huge aircraft into the air. Today we’ll be talking about the biggest commercial jet engine in the world the GE9X!
The GE9X is a turbofan jet engine developed by General Electric Aviation for the upcoming Boeing 777X aircraft. It’s regarded as the world’s biggest and most powerful jet engine having a massive diameter of almost 3.5 meters, which is bigger than the width of the 737 fuselage!
It also sports a massive amount of thrust totaling over 100,000 pounds of thrust, which is over 30,000 pounds of thrust more than the red-stone rocket that put america’s first astronaut into space!
The GE9X is the successor of the current GE90 being used on the 777-300ER and 777-200LR. The new “X” variant will power the new 777X series of aircraft and had a successful first test flight on the type on the 25th of January of this year, and is currently undergoing its certification process with the 777X.

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 and achieve an approximate 10:1 bypass ratio, a 60:1 overall pressure ratio and margin to Stage 5 noise limits.
All of the above specifications basically puts the GE9X as the absolute most efficient and powerful engine in its class, and as av-geeks ourselves we can’t wait to see it go into service on the 777X and experience its amazing features first hand.
