Boeing Test-Flies Eco-technologies

Boeing launched its ecoDemonstrator 787 in Seattle this week, to start flight-testing more than 25 new technologies aimed at improving fuel efficiency and reducing noise. The new round of testing, using 787 Dreamliner ZA004, will evaluate software and connectivity technologies related to operational efficiency, remote sensors to reduce wiring, aerodynamic and flight control improvements for greater fuel efficiency, and icephobic wing coatings to reduce ice accumulation. In July, the 787 completed flight tests for an acoustic ceramic matrix composite nozzle designed by Boeing to reduce weight and noise.

The ecoDemonstrator program last flew in 2011, using an American Airlines Next-Generation 737 to test 15 technologies, including winglets that will improve fuel efficiency by up to 1.8 percent on the new 737 MAX. Next year, the program will test more technologies on a 757 in collaboration with TUI Travel Group and NASA, Boeing said this week.
