Boeing, Lufthansa Group, and Rolls-Royce have partnered to test new aviation technologies aimed at improving fuel efficiency and reducing aircraft noise under Boeing’s 2026 ecoDemonstrator Explorer program.
The tests, scheduled to begin later this month at Boeing’s site in Glasgow, Montana, will use a Boeing 787-9 Dreamliner equipped with Rolls-Royce Trent 1000 engines.
The aircraft is slated for future delivery to Lufthansa after the completion of the flight test campaign, which is expected to continue through mid-August.
The flight test program will assess two key innovations aimed at improving aircraft performance and environmental efficiency.
One is the Next Generation Inlet, a reduced-length engine inlet demonstrator incorporating advanced acoustic treatments. The design supports the integration of more fuel-efficient engines on future aircraft while reducing engine weight and aerodynamic drag without compromising noise performance.
The second focuses on modified departure and arrival procedures, including Intelligent Operations flight paths. These flight paths are generated using multiple operational data sources to identify routes that can improve fuel efficiency while reducing aircraft noise around airports.

The technologies are being evaluated under Phase III of the US Federal Aviation Administration’s Continuous Lower Energy, Emissions, and Noise (CLEEN) program, which supports the development and testing of technologies that improve aircraft efficiency while lowering emissions and noise.
Lane Ballard, Chief Technology Officer at Boeing, said that the technologies being evaluated have the potential to further improve aircraft performance for airline customers and industry partners.
Grazia Vittadini, Chief Technology Officer of Lufthansa Group, noted that the airline’s long-standing partnership with Boeing continues through the ecoDemonstrator Explorer program, with the collaboration focused on evaluating technologies that could improve fuel efficiency, reduce noise, and validate their performance in operational conditions.
Alan Newby, Director of Research and Technology at Rolls-Royce, remarked that the program builds on years of collaboration between the companies to test technologies in real-world operating environments.
Rolls-Royce is providing engineering support and oversight for operation of the engine fitted with the Next Generation Inlet during the trials.
Julie Marks, Executive Director of the FAA’s Office of Environment and Energy, emphasized that the tests demonstrate how collaboration between government and industry supports the development and integration of advanced technologies into current and future aircraft.
Since its launch in 2012, Boeing’s ecoDemonstrator program has tested more than 260 technologies in operational environments to evaluate improvements in aircraft safety, fuel consumption, emissions, noise reduction, operational efficiency, and passenger experience.
The program helps mature technologies that support airline fleet modernization strategies while improving fuel economy and reducing noise emissions.
The 2026 ecoDemonstrator Explorer campaign continues Boeing’s efforts to evaluate technologies that can be incorporated into future commercial aircraft to improve operational performance and environmental sustainability.
