Uncertain Future For The 777x



Background Information

Boeing’s latest aircraft, the 777-9x, is part of the new generation of twin-engine widebody jets and was first announced in 2013 in response to the Airbus A350. The flagship aircraft is marketed as the world’s largest and most efficient twin-engine aircraft, combining features of the Boeing 787 and iconic Boeing 777. It features an array of new technologies, such as folding wingtips, new GE9X engines, and wider cabins. The 777x was slated to be delivered in 2020, but the date has been constantly pushed back and delayed due to multiple setbacks and obstacles throughout the years, such as the 737 MAX incidents and the pandemic.

Latest Updates

The future of Boeing’s newest aircraft is facing more uncertainties as it’s first delivery has been pushed back even further to late 2023.  This recent delay was caused by updated certification requirements for the 777x and the ongoing pandemic, and is going to cost Boeing a steep $6.5 billion charge on top of the serious impacts of the delay on customers. This new delay pushes the aircraft’s delivery 1 year later than the last delay in 2022, and over 3 years later than the original scheduled delivery in 2020. The 777x is now scheduled to enter service around early 2024, which is 4 years from the initial release.

The lengthy delay in 777x’s delivery brings unfortunate and possibly detrimental news to the aircraft’s success. As a result of the delay, airlines who have ordered the jet are considering switching their orders to another aircraft in replacement, which could seriously damage the aircraft’s future. For example, the Dubai carrier Emirates Airlines is rumored to swap 30-40 orders of their 115 orders to the 787 Dreamliner after already reducing their original 156 orders of the 777x in 2019. This decision could mean huge setbacks to the 777x’s production, since Emirates is the biggest customer for the program. If this decision is officially made, the orders for the 777x from Emirates would be almost half of what the airline originally planned to order.

Emirates has not been the only customer to reduce their orders since the initial launch. The number of confirmed orders for the Boeing 777x has already reduced by over half since the original launch of the aircraft. The aircraft’s confirmed orders have dropped from 309 originally to just 191 orders. These remaining orders are also becoming increasingly uncertain, as airlines are becoming more and more likely to change their order plans with the constantly changing decisions. Customers such as Lufthansa, Etihad, and Cathay Pacific are even considering replacing some of their 777x orders for other aircraft, which could decrease the number of confirmed 777x orders even more.

Overall, with all the continuous delays in the 777x program, the future for Boeing’s flagship may not look too bright. The 777x delivery date will possibly be even further delayed in the near future, and that might cause even more airlines to back out of their orders. Currently, the success of the 777x program is looking slim, but it could still work out eventually if the orders are delivered on time. The difficulties shown in the 777x program may unfortunately signal the end of the production of huge jets. The 777x may be the last of these types of large aircraft.

Could Boeing’s Transonic Truss-Braced Wing Airliner be the Sky Revolution we’ve been Waiting for?



NASA/The Boeing Company

Boeing’s Transonic Truss-Braced Wing (TTBW) airliner is a radical rethinking of aircraft design that could redefine standards of efficiency and sustainability. The concept, first developed in 2010, is now being built as a full-scale demonstrator with ambitious goals for fuel efficiency. If the project proceeds as planned, Boeing expects that planes of this design could be operational between 2030 and 2035.

In January 2019, Boeing revealed its innovative concept – the Transonic Truss-Braced Wing (TTBW) airliner. A result of a collaborative project with NASA that began in 2010, this concept aircraft incorporates a lightweight, ultra-thin, and highly aerodynamic wing design, supported by diagonal trusses. The design aims to provide optimal fuel efficiency. The TTBW is intended to fly up to Mach 0.80, similar to current jetliners’ speed but faster than any preceding truss-braced wing concept.

With a wingspan of 170 feet (51m), the TTBW concept plane is smaller than the A350 and the 787 Dreamliner, but still larger than the 737 MAX 8, which it surpasses by 53 ft (16m). A crucial factor in the TTBW design is its modified wing sweep and ultra-thin design, which minimize the induced cruise drag of the high aspect ratio wing. Wind tunnel tests have so far shown a remarkable 9-10% reduction in fuel burn for the wings alone. NASA and Boeing hope that when combined with other emerging technologies, the plane could achieve a 30% reduction in fuel burn compared to current next-generation narrowbody jets, like the A320neo or 737 MAX.

“Together with expected advancements in propulsion systems, materials, and systems architecture, a single-aisle airplane with a TTBW configuration could reduce fuel consumption and emissions by up to 30% relative to today’s most efficient single-aisle airplanes, depending on the mission,” stated Boeing.

To tackle the logistical issues associated with large wingspans, Boeing plans to use folding wingtips, a feature showcased on the 777X. The TTBW design proposes a significant adaptation where the wings would fold almost in half, with the truss providing support. This design could help circumvent difficulties related to fitting the aircraft into airport gates or hangars.

A New Era of Sustainable Aviation

Despite the fact that many concept aircraft proposed by Boeing and Airbus never materialize, researchers have confidence in the TTBW’s potential for mainstream use. Since 2010, Boeing has been developing the TTBW design through its partnership with NASA in the Subsonic Ultra Green Aircraft Research (SUGAR) program. They envision aircraft based on this design being operational by 2030-2035.

The current TTBW design, known as the X-66A, recently received its ‘X’ designation from the US Air Force. The ‘X’ refers to experimental aircraft designs that explore new technologies. The X-66A is the first X-plane designed specifically to usher in “a new era where aircraft are greener, cleaner, and quieter.”

The TTBW design does come with some challenges, such as fuel storage, due to the wings being much thinner than conventional airliners. The project is also banking on the integration of advanced propulsion systems, so its viability also depends on technological advancements in other areas.


Moving Forward with a Full-Scale Demonstrator

Transonic Truss-Braced Wing

Boeing announced a full-scale demonstrator in January, which will use a shortened MD-90 airframe. The demonstrator is scheduled to undergo a year of flight testing at the NASA Armstrong Flight Research Center in 2028. Boeing has proposed two potential designs for TTBW narrowbodies – the VS-1 and VS-2 – that would accommodate between 130–160 and 180–210 passengers, respectively.

Pratt & Whitney will power the demonstrator with its PW1100G geared turbofan. With single-aisle aircraft accounting for nearly half of worldwide aviation emissions due to their extensive use, NASA aims to target this market segment for significant emission reductions.

$1 Billion in Funding

NASA has pledged to invest $425 million into the project over the next seven years, with Boeing and partners committing $725 million during the same period.

NASA Administrator Bill Nelson stated, “Our goal is that NASA’s partnership with Boeing to produce and test a full-scale demonstrator will lead to future commercial airliners that are more fuel efficient, with benefits to the environment, the commercial aviation industry, and passengers worldwide. If we are successful, we may see these technologies in planes that the public uses in the 2030s.”


As Boeing seeks a successor to the 737 family by the early 2030s, the TTBW concept could play a crucial role in shaping its future narrowbody designs. While this groundbreaking redesign of conventional aircraft will undoubtedly face certification challenges, the significant funding and progress made on the TTBW suggest that we may be hearing more about this concept in the years to come.

What potential impacts do you foresee the Boeing Transonic Truss-Braced Wing (TTBW) airliner having on the future of commercial aviation, particularly with regards to sustainability and fuel efficiency? Let us know in the comments below.
