One of the 777X's most noticeable design elements will be its folding wings. Advocate for heavier-than-air flight. Boeing has pushed the 777x's airport advantage throughout the program’s development and addressed concerns over the folding wings to the satisfaction of regulators. On landing, the wingtips automatically fold within 20 seconds of the aircraft slowing to 50kts. This is one of many tests before the 777X takes to the skies later this year pic.twitter.com/KJ5BabExDY, — Boeing UK & Ireland (@BoeingUK) 24 June 2019. The 777-8 provides seating for 384 passengers and has a range of 8,730 nmi (16,170 km) while the 777-9 has seating for 426 passen… One of the 777X's most noticeable design elements will be its folding wings. The first and most important reason to add the folding mechanism to the wingtips was so that the giant bird could access a greater range of airports. The Boeing 777X models will sport folding wingtips, a first in commercial aviation. The two variants, the -8 and -9, can now use the wingtips without any form of restrictions commercially. Sign up to our daily aviation news digest. Courtesy Boeing We were live from the Everett factory chatting with the amazing #777X team and getting an exclusive view of the world’s most advanced composite wing. The wings are so long that to fit at standard airport gates, each has … This new technology comes in the form of the Boeing 777X. Boeing has, however, collaborated with Germany’s Liebherr Aerospace to develop a mechanism to fold up the 777X’s wingtips once the plane is on the ground to enable it to be processed at the same gates as the 777. Kelsey Campbell-Dollaghan. With its wings folded, there’s little difference in terms of the gate and taxi operations and means customers of the 777 can easily interchange their new 777X with the 777 classic without any major headaches. Our teams in Seattle will continue ground tests as we develop our newest twin-aisle jet. Within two years, Boeing had received 326 orders for the type. Boeing’s massive wing-folding 777x just flew for the first time . The decision was made to shorten the wingspan while on the ground to 212 feet by hinging the wingtips. Usually, adding so much mass to an aircraft would mean a heavier plane, thereby negating the benefits of the wider wingspan. The wingspan of the aircraft will be 235 feet wide, and when the wingtips are folded, it will reduce the span to 212 feet wide. The company has tried to make the system fit as … Taking all this into consideration, there must have been a strong case for adding folding wingtips to the Boeing 777X. Please Support us by turning off your adblocker. Today we are getting a first look at this unique feature. Boeing shows off its newest plane's foldable wings. However,the new plans call for folding only 10'. The re-shaping has led to a higher lift-to-drag ratio, which in turn increases usable fuel bulk from 320,863 to 350,410 lb. Tendentially, longer wings would have an higher weight and foldable mechanism surely add extra weight too, but thanks to new materials, new wings should be almost as heavy as previous ones. wide body and long haul, with new technologies that makes it the largest and most fuel efficient twin-engine commercial jet. The 777X will be the only commercial jet in widespread use to employ a hinged design—a feature that to date has only been seen on military jets. It becomes even more of an issue when those additions require separate certification, adding layers of paperwork and red tape to the development process. BOEING . Its huge 235 ft 5 in wingspan is a full 11 feet longer than its predecessor, making it too wide to land at a Code E airport. Here’s why it needed those beautiful folding tips to its wings. The FAA has recently approved the proposed designs for the newest version of the 777, a twin-aisle, twin-engine aircraft that’s built around fuel efficiency, with a massive wingspan of 235 feet, which is too wide for most airports. But due to various events in the early part of the year, the target date was pushed back. Journalist @ Simple Flying. Here’s how the aircraft’s long wings and giant engines boost its efficiency. Today we are getting a first look at this unique feature. Adding complexity to an aircraft is never a cheap thing. The plane's party trick means it should be able to land anywhere in the world. Sign up to our daily aviation news digest. ft.). The decision was made to shorten the wingspan … The folding wingtips will allow the aircraft to fit into gates where the existing models of the 777 can go, despite a longer wingspan. The FAA granted Boeing certification on the basis of the following provisions: More than one means must be available to alert the flight crew that the wingtips are not properly positioned and secured prior to take-off.Â. The Boeing 777X is an eye catching plane for many reasons. With new breakthroughs in aerodynamics and engines, the 777X will deliver 10 percent lower fuel use and emissions and 10 percent lower operating costs than the competition. “The folding wingtips are simple and highly reliable with redundant deploying, retracting and locking mechanisms. On Wednesday, the company showed just how they'll work. But public mistrust of the airline’s fastidiousness in respect of innovative technology is at an all-time high. The world just got its first look at the aircraft's amazing folding wingtips. The wing tips enable an extended span of seven metres, maximising fuel efficiency. As a result, the type will have a range of over 14,000 kilometers (8,699 miles). Boeing had initially hoped to begin the 777X flight test program in March. Aviation Daily speculate that, “GE will require several months to develop and test fixes to the engine and first flight now looks set to be more likely in the October-November timeframe.”, The aircraft is still slated for the commencement of passenger flights in 2020. This new aircraft, re-designed far and wide, has the best technologies: carbon fiber fuselage, folding winglets, a glass cockpit with 12 ”touch-screen display, wingflex from the Boeing 787, and new GE-9X engines. The new Boeing 777X has longer wings to improve efficiency, but has to adopt foldable wingtips to "fit" into all original airports that host its predecessor. However, the 777X uses a composite material for the wings, which is lightweight and allows it to add all that span without increasing weight. However, there are important differences between the original plan in 777 and the proposed plan in 777x. In aerodynamics, the longer and slimmer the wings, the less the drag will be. The 777X was launched in November 2013 with two variants: the 777-8 and the 777-9. The company was required to prove beyond doubt the load-bearing viability of the wingtips. Be in the know.

The Federal Aviation Administration has approved for commercial use the folding composite wingtips that will be installed on the upcoming Boeing 777-X program. Boeing has pushed the 777x's airport advantage throughout the program’s development and addressed concerns over the folding wings to the satisfaction of regulators. But the real stop-and-stare component of the 777X is its folding wings… In the course of their deliberations the FAA demanded several assurances from Boeing.
