Specifically, it employed computational fluid dynamics (CFD) in the development of the Airbus A350XWB, a technique that improves the external shape for minimum drag. Aerodynamic efficiency: Like the 777X, Airbus worked to make the A350 as aerodynamic as possible.Quiet engines: The Rolls-Royce Trent XWB engines are quieter and more fuel-efficient than its current competitors.

This is not so much as you'd notice, but the small movements allowed in the wings make for reduced drag and lower fuel burn. Adaptive wings: Taking inspiration from nature, the A350's wings actually 'flap' while in flight.It also has titanium and aluminum alloys to make it super light and robust. Lightweight construction: The A350 is made from 53% composite materials, which are lighter and more durable than traditional aluminum.The A350, despite its earlier release to the market, also pushed the boundaries with technologies on board. Cabin comforts: Inspired by the Dreamliner, the cabin of the 777X will be wider, with large windows, optimized pressurization, mood lighting and improved architecture for a more comfortable passenger experience.Aerodynamic efficiency: The raked wingtips, huge wingspan and all-new engines add up to significant fuel savings and greater efficiency.They are the biggest aircraft engines in the world, and the most efficient, making use of composite fan technology for more power and lower fuel burn. Biggest engines: The giant GE9X engines are all-new and designed specifically for the 777X.Folding tips: To keep the 777X in a lower size category and not to limit the airports it can use, Boeing has designed it with folding wingtips.Composite wings: The use of composite materials in the wing construction allows the 777X to have the biggest wingspan of any commercial passenger aircraft.Building on the success of its predecessor, the 777, and employing some advancements seen in the Boeing 787, its Boeing's most ambitious aircraft to date. The 777X will be the largest twin-engine jet aircraft in the world. While many of the improvements seen in the two widebodies are directed toward fuel efficiency, passenger comfort has played its part in the designs too. Both the A350 and the 777X have some incredible, next-generation technology onboard.
