The tests will take place on a Boeing 787-9 Dreamliner, which will serve as the 2026 ecoDemonstrator Explorer testbed. The aircraft, equipped with Trent 1000 engines, will undergo testing at Boeing’s facility in Glasgow, Montana, with flights expected to continue through mid-August.
The evaluation focuses on two key innovations. The first is the Next Generation Inlet, a reduced-length engine inlet featuring advanced acoustic treatments. The design is intended to support more fuel-efficient engines on future aircraft while reducing weight and drag without compromising noise performance.
The second involves modified departure and arrival procedures, including Intelligent Operations flight paths. These data-driven flight paths are designed to optimise fuel use while reducing noise impact on communities around airports.
“Boeing works tirelessly to deliver the aerospace innovations of today and tomorrow,” said Lane Ballard, Chief Technology Officer, Boeing. “The more efficient inlet and Intelligent Operations flight paths we’re evaluating on this year’s ecoDemonstrator Explorer are among the many promising concepts we’re working on. These enhancements have the potential to make our airplanes even more valuable to our partners, including customers like Lufthansa and suppliers like Rolls-Royce.”
“Lufthansa Group and Boeing share a long-standing partnership in aviation. We are pleased to support this year’s Boeing ecoDemonstrator Explorer program alongside Rolls-Royce,” stated Grazia Vittadini, Chief Technology Officer, Lufthansa Group. “Together, we aim to help advance aviation’s transformation by testing technologies with the potential to improve fuel efficiency, reduce noise and prove their value in real-world operations.”
“This program is the culmination of a decade of collaboration with Boeing, built on a shared ambition to reduce noise, improve efficiency and unlock more sustainable flight,” added Alan Newby, Director of Research and Technology, Rolls-Royce. “With Boeing and Lufthansa, we are building on our extensive research to test technologies in real-world conditions and see how they perform where it matters most – in service. We look forward to sharing insights and demonstrating how world-class partnership and innovation can deliver benefits for our customers and the industry.”
The technologies are being tested as part of Phase III of the Federal Aviation Administration’s CLEEN program, which supports the development of advanced solutions to improve fuel efficiency and reduce emissions and noise.
Since its launch in 2012, Boeing’s ecoDemonstrator program has tested more than 260 technologies in operational environments, focusing on improving efficiency, sustainability and overall aircraft performance.
