United Airlines announced today that it has selected GE Aerospace to supply engines for its expanding fleet of Boeing 787 aircraft. The airline has committed to acquiring 300 GEnx engines, which will enhance its existing fleet of 200 GEnx-powered 787s. This decision continues a long-standing partnership that dates back to 1968, during which United has utilized various GE engines, including the CF6, GE90, and CFM56-7B.
The GEnx engine is known for its impressive reliability, boasting a dispatch rate exceeding 99.98%. It is a preferred choice for long-haul flights on the Boeing 787 Dreamliner, making it integral to United’s operations. With this latest agreement, United Airlines becomes the largest operator of GEnx engines worldwide, reinforcing its trust in GE Aerospace’s capabilities.
Significance of the GEnx Engine
The GEnx engine has achieved a remarkable milestone, having surpassed 70 million hours of operation globally. It powers more than two-thirds of all active Boeing 787 aircraft, and with United’s new order, the total delivery pipeline for the GEnx now exceeds 1,800 engines plus necessary spare parts. Its durability and extended lifespan make it an attractive option for numerous airlines.
United’s current fleet includes over 81 Boeing 787 aircraft, which consist of the 787-9, 787-10, and 787-8 models. Specifically, the airline operates 48 787-9s, 21 787-10s, and 12 787-8s, with a further 140 on order. The upcoming deliveries will feature upgrades to United’s Polaris cabin and incorporate some of the largest in-flight entertainment screens available.
Technological Advancements and Environmental Impact
The GEnx engine is recognized as one of the fastest-selling jet engines globally, developed with **leading-edge technologies** that provide significant advantages. It offers a 1.4% reduction in CO2 emissions annually compared to its closest competitor over a standard 3,000 nautical miles flight. The engine utilizes advanced materials to achieve a lighter weight—approximately 300 pounds (136 kg)—and higher durability.
GE Aerospace has also integrated composite fan blades into the GEnx design, enhancing efficiency and reducing the total blade count to just 18. Notably, it includes the first FAA-approved 3D printed part, further showcasing GE’s commitment to innovation.
Mohamed Ali, President and CEO of GE Aerospace Commercial Engines & Services, expressed pride in the longstanding relationship with United Airlines, stating, “This deal will make United the largest GEnx operator in the world, and we’re honored they continue to choose us to power their success.” This agreement not only strengthens United’s fleet but also underscores the airline’s commitment to sustainability and operational excellence in the aviation industry.
