Boeing, Lufthansa and Rolls-Royce to flight-test ecoDemonstrator 787-9 tech to cut fuel burn and reduce airport noise
Boeing, Lufthansa and Rolls-Royce will conduct flight tests using a modified Boeing 787-9 ecoDemonstrator test bed to evaluate fuel-efficiency and noise-reduction innovations. The program will include acoustic assessments of a next-generation inlet with changes to the shorter nacelle structure for improved noise performance.
