Going For Great: In A Deal Valued At $6.5 Billion, GE Jet Engines Will Power American’s New Dreamliner Fleet
By Tomas Kellner – American Airlines, which helped launch GE into commercial aviation 45 years ago, said it would power 47 additional new Boeing 787 with GE Aviation’s GEnx-1B engines. The $6.5 billion deal includes a 20-year service agreement. This order follows a previous order for 42 such planes placed several years ago.
Airlines have ordered more than 2,000 GEnx engines since 2004, when Boeing selected the model for its 787 Dreamliner jets. Eager to save weight and improve efficiency, GE engineers took the GE90, the world’s most powerful jet engine developed a decade earlier, and remodeled it.
The GEnx has already entered the record books. In 2011, a GEnx-1B-powered Dreamliner flew halfway around the world on a tank of gas, then finished the job on the next tank. The journey set a weight-class distance record for the 10,337-nautical mile first leg and a record for quickest around-the-world flight at an astonishing 42 hours and 27 minutes.
What’s next? GE engineers could upgrade the engines with space-age materials called ceramic matrix composites, or CMCs. CMCs can handle temperatures as high as 2,400 degrees Fahrenheit and withstand the punishing forces inside the engines. more>
