NASA’s Environmentally Responsible Aviation Project, in collaboration with the Federal Aviation Administration (FAA) and Pratt & Whitney, completed testing of an Ultra High Bypass Ratio Turbofan Model in the 9’ x 15’ Low Speed Wind Tunnel at NASA Glenn Research Center. The fan model is representative of the next generation of efficient and quiet Ultra High Bypass Ratio Turbofan Engine designs.
Ultra High Bypass Integrated System Test Testing of an Ultra High Bypass Ratio Turbofan model in the 9-by 15-Foot Low Speed Wind Tunnel. Pratt & Whitney designed the experimental engine to meet new efficiency and noise reduction targets for commercial aircraft set by NASA and the Federal Aviation Administration. The 9-by 15 tests analyzed two noise reduction technologies.
