The design philosophy centers on maximizing fuel efficiency and reducing noise, achieved through a massive 128-inch (3. Mounted on the upper surface of each wing in an underslung pylon, these engines are rated to produce a massive thrust of approximately 134,000 pounds-force (600 kilonewtons) each.

Developed by General Electric as the GE90-115B derivatives for the passenger variant and the GEnx-2B67 for the freighter, these powerplants are engineering marvels designed to deliver exceptional performance, reliability, and efficiency for the demanding long-haul and high-capacity cargo sectors. To manage the complex airflow interactions between the engine and the wing, particularly at low speeds and high angles of attack, the aircraft features vortex generators and an intricate wing leading-edge design.
Technical Specifications and Design Philosophy At the core of the 747-8's power is the General Electric GE90-115B, which holds the distinction of being the world's largest commercial jet engine. The GE90 and GEnx families incorporate advanced high-bypass ratios, with the GE90 exceeding 10:1, meaning a large volume of air is bypassed around the core for greater thrust with less fuel.

The efficiency is further enhanced by the aircraft's ability to fly at optimal altitudes and speeds, unaffected by the performance penalties that can affect twin-engine jets over extreme oceanic crossings. This, combined with advanced aerodynamics and lightweight composite materials, ensures that the 747-8's fuel burn per passenger-mile is competitive with modern twin-engine wide-bodies on comparable routes.
