Boeing has completed the configuration of the 777-9, the first member of its new 777X family, which is set to boost cargo capabilities.

The aircraft manufacturer says the basic design has been established, and configuration trade studies completed. Wind tunnel test results, aerodynamic performance and structural loads have also been evaluated.

Their completion allows the 777X team to begin detailed design of parts, assemblies and other systems for the aircraft. As detailed designs are completed and released, production can begin. Boeing says that it is on track to deliver the first 777-9 in 2020.

“The program is right where we want it to be,” says Bob Feldmann, Boeing’s vice president and general manager of the 777X program. “We have an airplane and production system that are on track and on schedule, and we remain laser focused on meeting our commitments to our customers.”

The 777X family includes the 777-8 and the 777-9, which provide significant range, payload and fuel burn advantages, according to Boeing.

The 777X will be the largest and most efficient twin-engine jet in the world, with 12 per cent lower fuel consumption and 10 per cent lower operating costs than the competition.

According to Boeing, the 777X team has worked closely with airline customers and key suppliers to reach this stage.

“It’s great to see the airlines and industry team side-by-side with us as we achieve this important milestone,” says Feldmann. “The team has followed a disciplined process to complete all of the requirements for this stage of the program.”

The 777X program has received orders and commitments for 320 aircraft from six customers worldwide. Production is set to begin in 2017.
