First look at the Boeing 777x prototype; The new giant of the sky

Boeing's latest wide-body aircraft, the 777x, was unveiled at the Dubai Air Show last week, showcasing new capabilities that promise a powerful bird. In airlines. In this article, we'll take a look at some of the most important features of the prototype on display. Many will face many.

  • Air transport will not return to normal by 2024

Originally expected to be delivered to the First customer in 2020, it has faced many delays, and now its First delivery is now scheduled for the end of 2023. Although Emirates CEO Tim Clark said the date would change further, the company said Boeing Senior Vice President of Commerce Mike Fleming confirmed the 2023 target on Sunday. In any case, the aerial display of this vehicle in Dubai marked a big step for this aircraft model. This was the First time the plane had left the United States; Where four 7777x prototypes have passed more than 1,700 hours of flight testing, about half of the 3,500 flight tests performed by the original 777 and the 787 Dreamliner 787 before receiving FAA certification.

Boeing 737 Max, which left a total of 346 dead. "As a result of what happened to Max, regulators, like Boeing, are thinking more sensitively about how to approach certification," Fleming told a news conference. "They think more about what they do and how they do it."

It's huge, really huge! Boeing plans to produce two 777x models. The larger aircraft, which will be the 77-9, and a smaller model, the 777-8. At 76.72 meters long, the Boeing 777-9 is taller than the 77700 with a wider cabin.

However, the length of the wings is what really stands out on this aircraft. With a wingspan of 71.5 meters compared to the 64.82 meters of the 777 version of the 300ER, this aircraft will be too large to be present in many airports around the world.

To solve this problem, Boeing designed a 4-meter folding wingtip. As the plane lands and heads to the hangar, the pilot adjusts the tips of the wings to fold upward. When it is ready to take off again, the tips of the wings can be opened.

777-9 has a maximum capacity of 426 passengers in a configuration with two flight classes, although The actual capacity will depend on the airline's decision to arrange the cabin. According to the Boeing 777x, it has features such as better pressure and more humidity in the cabin, larger windows and less noise, which have been developed for Dreamliner.

Although ordinary travelers will probably only realize this, this is not all that 777x has borrowed from Dreamliner. The aircraft also uses the 787 pilot panel design and uses an upgraded set of avionics equipment with a display.

The aircraft is also powered by GE's new GE9X engine, which was built specifically for the 777x. The engines, which produce 490 kN of propulsion, are about the size of the body of a Boeing 737.

The interior of the 777x prototype on display at the Dubai Motor Show bears little resemblance to the final layout for passengers, and due to the flight tests they are undergoing, the interior is covered with tanks, desks and workstations for flight test engineers. .

A set of regular black tanks are some of the features Which draws attention to the N779XW register, which is even the First of four prototypes, when walking inside a true 777x prototype.

There are 24 tanks, each containing about 120 gallons, or 450 kg of water. According to Matthew England, flight test engineer at the Dubai Exhibition Center, the gallons are connected by a relatively complex piping system and are used to change the weight balance of the aircraft for various flight tests.

Engineers can transfer water to different parts of the aircraft and change the weight distribution during test flights as needed. It is impossible to judge the final experience of the passengers on the aircraft currently undergoing tests. But there is no doubt that the 777x is very large. The current prototype does not have shelves above the passenger's head, and there is a large gap between the number of seats. But walking and sitting on 3-4-3 economy seats feels extraordinarily spacious, and it seems that this situation still persists after entering the passenger service, even with full chairs.

In addition, a handful of economy chairs are scattered between water barrels and engineering workstations. Lightweight seats are commonly found on test aircraft, but something different about this aircraft. Old-fashioned in-flight entertainment displays and plenty of cushions make them appear to be from the mid-2010s.

These seats primarily act as space fillers, and sometimes engineers may attach weights to them to simulate passengers. But the seats are in the front row for real use.

Used chairs. However, as the entire cabin is not yet equipped with overhead masks, some of them require extra oxygen for emergency pressure relief.

These seats also feature entertainment equipment during There is no flight, and they should watch the movie in their gadgets for flights such as the 15-hour flight from Seattle to Dubai.

The aircraft will likely need about 1,700 or 1,800 more hours of flight testing to be certified, but Boeing insists it can begin delivery in late 2023 by avoiding unexpected regulatory obstacles.

Boeing currently has 351 orders and commitments from eight airlines, including All Nippon Airways, British Airways, Cathay Pacific, Emirates (Emirates), Etihad, Lufthansa, Qatar Airways and Singapore Airlines.

The aircraft giant is still Did not announce which company n The plane will be delivered and, according to Boeing officials, no decision has been made yet./li>
