Why does the 777X not have chevrons?
The basic reason that the chevron will not be used on the 777X is that it is no longer needed. While the serration provides forced mixing of the fan stream with the ambient stream, thereby reducing noise, it comes at a cost in terms of drag.
What is different about the Boeing 777X?
The Boeing 777X is the latest series of the long-range, wide-body, twin-engine jetliners in the Boeing 777 family from Boeing Commercial Airplanes. The 777X features new GE9X engines, new composite wings with folding wingtips, greater cabin width and seating capacity, and technologies from the Boeing 787.
What is special about Boeing 777X?
Boeing’s newest aircraft, the Boeing 777X, flew for the first time in January 2020 after lengthy delays. It’s the largest twin-engine jet in the world and Boeing’s latest new aircraft to fly since the grounding of the 737 Max.
Who makes the engines for the Boeing 777X?
General Electric GE9X
The General Electric GE9X is a high-bypass turbofan developed by GE Aviation exclusively for the Boeing 777X. It first ran on the ground in April 2016 and first flew on March 13, 2018; it powered the 777-9’s maiden flight in early 2020.
Who makes the 777 nacelle?
In late 2017, Spirit AeroSystems began production on Boeing’s next-generation widebody airliner, the 777X, featuring fuel-efficient new engines from GE and a composite folding wing. Spirit provides the forward fuselage, nacelles and struts for both the 777 and 777X.
Is 777X wider than 777?
The first big difference between the 777X and the 777-300ER is the wingspan. Both 777X variants have a wingspan of 71.8 meters, roughly 15\% bigger than the 777-300ER’s wingspan. Because the wingspan is so huge, the wings’ actual ends need to fold upwards to allow the plane to use normal gates.
Who makes fuselage for Boeing?
Specifically, this is a role fulfilled by Spirit AeroSystems, which produces the fuselages before sending them to Boeing to join the assembly line. However, Spirit is based in Wichita, Kansas, whereas Boeing’s 737 factory is in Renton, Washington.
What does Spirit AeroSystems make?
Spirit AeroSystems is one of the world’s largest manufacturers of aerostructures for commercial airplanes, defense platforms, and business/regional jets.
What makes the Boeing 777X so special?
Apart from being cheaper to run (by approximately one or two dollars per seat per hour of flight time), the 777X features modern technologies, such as the largest engines ever placed on a passenger aircraft. Manufacturers are also building the plane with the engineering principles for today’s world.
Why doesn’t the Boeing 747 fly in this climate?
Notably, the 747 is simply not designed for this modern climate. Apart from being cheaper to run (by approximately one or two dollars per seat per hour of flight time), the 777X features modern technologies, such as the largest engines ever placed on a passenger aircraft.
How will the 777X affect the rest of the quadjets?
And with engine improvements, larger airframes are achieving higher capacities. The 777 was a significant factor in the demise of the A340. Given the rate at which the other quadjets are being retired, it looks like the 777X will have a similar effect on the remaining four-engine models.
What is the difference between 777-8 and 777-200LR?
The 777-8 is a shorter version (69.8 meters compared with 76.7 meters). It will have lower passenger capacity but a higher range. Its range of 16,170 kilometers will make it a suitable replacement for the 777-200LR and a strong competitor for the A350-1000 (with a range of 16,100 kilometers).
