Commercial Aircraft Engine GEnx-1B70
 (787-8)

The GEnx is the fastest-selling, high-thrust jet engine in GE Aviation history with more than 2,700-plus engines in-service and on order. GEnx is the best-selling engine on the 787 Dreamliner in addition to powering the four-engine Boeing 747-8. Based on proven GE90 architecture, the GEnx engine offers up to 15% improved fuel efficiency and 15% less CO2 compared to GE’s CF6 engine. The GEnx engine represents a giant leap forward in propulsion technology, using the latest materials and design processes to reduce weight, improve performance and deliver a more fuel-efficient commercial aircraft engine. Key to GEnx engine's performance are its high pressure compressor, lean-burning combustor and lightweight durable composite materials, including the world’s first composite fan case and fan blades for commercial aircraft. With the highest pressure ratio compressor in commercial service today, the GEnx has the best fuel efficiency in its thrust class, enabling it to power many of the longest routes. These leading-edge technologies and the engine's elegant architecture bring in high operational reliability, excellent utilization rate and route flexibility for more flights per year and more revenue for airlines. Designed specifically for the Boeing 787 Dreamliner family, the GEnx-1B engine delivers up to 15% better specific fuel consumption than its predecessor, a 2% fuel burn advantage over its competition and a 1% advantage with respect to fuel burn retention.
