The Advanced Ducted Propulsor in the Upgraded 9- by 15-Foot Low Speed Wind Tunnel

A low pressure ratio, variable pitch scale model of an aircraft engine fan was tested in the NASA Glenn Research Center 9- by 15-Foot Low Speed Wind Tunnel. The Advanced Ducted Propulsor was designed by Pratt & Whitney in the 1990’s and has been part of multiple wind tunnel test campaigns over the intervening years. The most recent test served to commission the wind tunnel after an improvement project that lowered the background noise in the facility. A secondary benefit of the commissioning test was to generate new aerodynamic and acoustic measurements of this propulsor with the latest data systems and processing. The results of the test are reported as an open and non-proprietary data set for the aeroacoustics and propulsion community. New capabilities of the facility are also highlighted.
