Boeing’s New 777X Comes With The World’s Largest Engine – GE9X

Boeing 777X

Boeing has put built the world’s largest fanjet engine with the world’s biggest twin-engine aircraft, the 777X. Boeing has delivered pictures that feature the prototype 777X – still unfinished though – in Boeing’s Renton, Washington construction hangar. A General Electric GE9X engine has been attached to the port wing, and the aircraft is being planned for its maiden flight scheduled for later in 2019.

The development of prototype 777X has been going on since 2017. Boeing has two versions of the long-range and wide-body airliner prepared. The prototype 777X is being named as the biggest and the most economical twin-engine jet in the world. It relies on the design and interior innovations from Boeing 777 and 787 Dreamliner. It is being said that it will be able to working routes such as the intercontinental route of New York to Singapore.

The price for the versions starts at 350 million USD. It is being also said that the 777-8 and 777-9 variants will be able of flying up to a limit of 8,700 nautical miles (16,110 KM) while taking passengers anywhere between 350-422. This has been made achievable by making use of a composite spar that was made of over 400 miles of carbon tape. This carbon tape was cured in an autoclave – specially built – thus allowing the 777X to feature a wingspan of 72 meters.

In order to make use of this huge wing, the 777X will rely on power from two GE9X turbofan jet engines. GE Aviation was able to bring down the number of fan blades to 16 and thus lower the weight of the engine while enhancing its power and size. It was able to achieve this by incorporating a new scale of 3D printing in the fan case and blades.

The GE9X measures in at 3.41 m in diameter thus rendering it wider than a Boeing 737’s fuselage. Despite the size, it can provide with 100,000 pounds of thrust and also offers a 10% better efficiency as compared to the GE 90 engines. The wide use of ceramics also allows the engine to work even at temperatures of 1,316 C.
