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. 01 million pounds (458 metric tonnes) into the sky.
747-8 Engines Hump Ground Clearance Fans
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. Furthermore, the 747-8's distinctive "hump" is not merely aesthetic; it creates the necessary ground clearance for the large-diameter GE90 fans, preventing foreign object damage during takeoff and landing on unprepared surfaces.
In the ultra-long-range passenger variant, the 747-8 can continue safely on a single engine for an extended period, opening up vast routing options over remote areas like the North Atlantic and polar routes. These sophisticated machines are the only commercial jet engines currently in production that feature a distinctive quad-engine configuration, a design choice rooted in history yet justified by specific operational advantages.

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. This immense power is necessary to accelerate the 747-8's maximum takeoff weight of nearly 1.
