Boeing has resumed flight tests with the ecoDemonstrator 787 Dreamliner to develop and validate new technologies that improve efficiency and reduce emissions.
The aircraft will, over several weeks, assess more than 25 technologies designed to improve aircraft fuel efficiency and reduce noise.
The program accelerates the testing, refinement and use of new technologies and methods that can improve efficiency and reduce noise. This 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.
The ecoDemonstrator is focused on technologies that can improve airlines' gate-to-gate efficiency and reduce fuel consumption, emissions and noise.
The ecoDemonstrator 787 tests include:
- NASA Airborne Spacing for Terminal Arrival Routes (ASTAR) to improve landing efficiency.
- New greenhouse gas sensors evaluated in collaboration with Japan Airlines and others.
- Real-time turbulence reports generated in collaboration with Delta Air Lines to mitigate moderate or greater turbulence events, resulting in improved flight efficiency and passenger comfort.
- Instrument landing systems for new and older aircraft to optimize landings and reduce fuel use.
- On-Board Wireless Sensor Network and Micro Electro Mechanical Systems microphones to reduce wiring and weight.
- Outer wing access doors made from recycled 787 carbon fiber to reduce material costs and factory waste.
The ecoDemonstrator 787 completed flight tests in July for an acoustic ceramic matrix composite nozzle designed by Boeing to reduce weight and noise. These tests were part of the FAA Continuous Lower Energy, Emissions and Noise (CLEEN) Program, a competitively bid five-year program with costs shared by participants.
In 2011, with an American Airlines Next-Generation 737, the ecoDemonstrator Program tested 15 technologies including aspects of the Advanced Technology Winglet that will improve fuel efficiency by up to 1.8 percent on the new 737 MAX. In 2015, the ecoDemonstrator Program will test more technologies on a 757 in collaboration with TUI Travel Group and NASA.
The Rolls-RoyceTrent 1000 engine is powering the latest phase of Boeing ecoDemonstrator.
