An amazing comparison between the size of the GE9X engines and the Boeing 737-8. It is housed in a 14.5 foot nacelle, and its composite fan is more than 11 feet in diameter. If all the test flights go well, Emirates is set to launch operations of the 777X in mid-2020. Il GE9X è il più grande e più potente motore turbofan per aerei civili mai costruito. Boeing’s largest twin-engine aircraft, the 777X, is scheduled to rollout next month. It is housed in a 14.5 foot nacelle, and its composite fan is more than 11 feet in diameter. And the GE9X is supposed to have a fan 132"(11-freakin'-feet!)
GE9X Commercial Aircraft Engine The world's next great engine. Anything related to aircraft, airplanes, aviation and flying. It is scheduled to take place in the second quarter of this year. Yeah, I took the tour at Boeing in Everett, they said the 737 fuselage can fit inside the cowling for that sucker.

Designed specifically for the 777X by @GEAviation, the engines have the largest fan ever produced for a commercial jet! At nearly 13 feet in diameter, the GE9X is the largest jet engine ever built. It features a composite fan case containing 16 fourth-generation carbon-fiber composite fan blades, which push air into an 11-stage high-pressure compressor with a 27:1 pressure ratio. To harness the power of the engine, the GE9X is equipped with a low-pressure turbine module and the Accessory Drive Train (ADT) kit, which regulates the unit and distributes its energy for secondary functions by means of an inlet gearbox, transfer gearbox, and Accessory GearBox (AGB). Furthermore, the GE9X engine features higher bypass and compression ratios and is expected to improve fuel efficiency by 10% over the GE90. I think this was when they were testing it for airliner strike.

Il GE9X è stato prodotto per essere montato sul nuovo Boeing 777X, velivolo che risulta essere il 10% più efficiente rispetto alla diretta concorrenza. It incorporates GE’s most advanced technologies that have been developed over the last decade to make it the most fuel-efficient engine in its class while also delivering unmatched performance. Based in California. “These tunnels and caves are a closely guarded secret,” says GE Aviation spokesman Rick Kennedy. We recently installed both GE9X engines on the first #777X flight test airplane. The mammoth piece of machinery is the largest turbine aircraft engine in the world. Its blades and fuel nozzles are 3D printed, because 3D printing allows GE to produce more complex and efficient shapes. According to GE, ground testing of the GE9X development engine will enable data to be gathered on the engine’s overall and aerodynamic performance, mechanical verification, and aero-thermal system validation leading up to flight testing and certification before entering service at the end the decade.

Il motore, dotato di due alberi rotanti, è in grado di produrre fino a 470 kN di spinta, sul livello del mare, mantenendo un BPR, rapporto tra flusso d’aria accelerato dal Fan e flusso che attraversa il ciclo turbogas, intorno a 10:1.L’elevato valore di OPR (Overall Pressure Ratio), circa 60:1, ossia la pressione tra primo compressore ed ultima turbina, permette di ridurre del 5% il consumo specifico.Nel 2017, dopo alcuni anni di test e certificazioni, il GE9X batte il precedente record e produce la massima spinta raggiunta da un motore per velivoli civili: quasi 600 kN netti di spinta. Esso verrà utilizzato dalla nuova famiglia di velivoli bimotore, Boeing 777X, e recentemente ha ottenuto l’approvazione da parte del colosso americano FAA. all rights reserved.

It also has the lowest NOx emissions of any GE engine (on a per-pounds-of-thrust basis). The GE9X engine is assembled in Durham, NC and Peebles, OH and is made of parts from the United States, Japan and Europe. The latter powers the fuel pump, oil pump, hydraulic pumps for the flight controls, an air turbine to start the engine, and other onboard systems, yet has 10 axles and nine accessories as opposed to the previous GE90, which has 11 axles and only eight accessories.

Considering pretty much every engine manufacturer sells new engines at a loss (Negative Engine Margin or NEM), I bet Boeing is paying a small fraction of the $41.4M. The engine is about the same size as the fuselage of a Boeing 737. 9 months ago. Now that’s a big engine! My dad flys 777-300ER and if you put a 737-6 or 7 beside it it almost looks like it can fit into the engine. The aircraft is still due to take its first flight. Helicopters & rotorcraft, airships, balloons, paragliders, winged suits and anything that sustains you in the air is acceptable to post here. The variance between max thrust and rated thrust for the GE9x is the same as the max take of thrust of … Il costo unitario sarà invece una cifra superiore ai 40$ milioni. Airbus A350 Fanboy. GE says that this relatively early testing was to ensure that the test data was available as soon as possible for the certification engines, which are scheduled to be installed in GE Aviation’s flying test bed for certification of flight testing in 2018. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. The engine is about the same size as the fuselage of a Boeing 737. Nonetheless, due to its aerodynamic efficiency and its larger 118-foot wing, the 777X will require less thrust than the GE90 powered Boeing 777. Close. Weight is saved by the extensive use of ceramic matrix composites (CMC), which allows the combustor and turbine to handle temperatures of up to 1,315º C for greater fuel efficiency and lower emissions. In the wake of the 737 This first test flight over the Mojave Desert went very well. To accommodate the aeronautical behemoth, the Peebles facility was recently upgraded with a larger air intake, extra fuel tanks to feed the giant engine, and high temperature gear to deal with the hotter, more efficient design.
The high pressure ratio of 27:1 (vs. 19:1 for the GE90) increases the temperature of the air by about 100 degrees Fahrenheit. It goes through extensive ground testing at GE’s facilities in Peebles, OH. First engine vs 1000 engine cost is also completely different. With a front fan spreading a full 3.35 metres, the GE9X is a world record holder and generates thrust in the order of 45 360 kilograms.
