The Boeing 777 is the world's most popular widebody aircraft, with over 2,353 orders and 1,709 deliveries. During its 28-year production run, the 777 was revamped just once, when Boeing introduced the 777-200LR and 777-300ER. The design remained relatively unchanged for the new generation models, with upgrades like new engines and minor performance improvements.
The 777X is becoming the first significant enhancement to the lineup and features substantial technical changes to the aircraft, which is part of the reason the industry highly anticipates it. While the aircraft's entry-to-service has been significantly delayed since its initial 2020 date, it promises to enhance the long-haul, widebody market with a fantastic aircraft, not just for operators but for passengers too. A recap of innovations found on Boeing's upcoming long-range product.
1 Curved wings The 777X is much more efficient than its predecessor, thanks to many improvements. Its new wings contribute to its aerodynamic efficiency significantly - these curved wings will represent the largest wingspan of any Boeing commercial plane at 235 ft, 5 in (71.75 m), a sizable increase over previous 777 models.
Like the 787's wings that inspired them, the 777X's wings are curved upwards from the root and downwards towards the tips. Boeing once again chose to use raked wingtips instead of conventional winglets. The gentle curve alters the airflow over the wings' surface, increasing lift and reducing drag.
