Renton - With a fan of composite material more than 11 feet (3.35 meters) in diameter, General Electric GE9X is the largest engine in the world.

It is the new engine of the Boeing 777X. It will be the largest and most efficient dual-aisle, twin-engine aircraft operating in the world, according to the North American manufacturer.

After many ground tests that began in March 2016, it was time for the first flight. For this, GE has just assembled a GE9X test engine on the wing of a B747-400, which will serve as a testing platform.

GE9X will consume 10% less fuel compared to the GE90-115B engine that currently powering most Boeing 777-300ERs.

Boeing engineers removed wing extensions of the 747 to accommodate this new load and mounted it alongside CF6-80C2 engines, which will also serve to compare metrics. Boeing engineers had to put the engine far from the edge of the wing at a slight angle (5 degrees) to maintain ground spacing, especially during landings.

GE has already produced four test engines. Two will now be sent to the Boeing plant to be assembled on the first prototype of the B777-9 in 2018, expected to fly in the early months of 2019 for the first time

GE9X will consume 10% less fuel compared to the GE90-115B engine that currently powering most Boeing 777-300ERs.

We will also see about a %30 CO2 emission reduction, below the standards of environmental regulation predicted for the next decades. (CAEP / 8)

More on the B777X

With an announced price of $ 429 million, the B777X will have a capacity of up to 375 passengers in the B777-8 version, and up to 425 passengers in the B777-9 version.

This giant of the skies has a wingspan of about 236 feet (72 meters), totally built of composite material with a system that allows folding the wings for better operation in the airports. A more spacious cabin with better ambiance and larger windows are also part of the evolution of the Boeing 777.
