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.

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.
