Boeing, Lufthansa German Airlines and Rolls-Royce will conduct flight tests for the “2026 ecoDemonstrator Explorer” from late July through mid-August.
The tests will use the “Next Generation Inlet,” designed for the installation of more fuel-efficient engines on future aircraft. The shorter engine inlet, featuring acoustic treatment, is intended to reduce weight and drag while maintaining noise performance. Departure and arrival procedures will also be modified to evaluate “Intelligent Operations” flight paths, which are generated by algorithms based on multiple data sources. The initiative aims to reduce noise around airports and improve fuel efficiency.
The ecoDemonstrator Explorer test aircraft is a Boeing 787-9 powered by Rolls-Royce Trent 1000 engines and is scheduled to be delivered to Lufthansa German Airlines at a later date. The tests will take place at Boeing’s site in Glasgow, Montana, United States.
