Abstract
The Advanced Noise Control Fan (ANCF) was utilized in the design, test, and evaluation for technical risk mitigation for many of the innovative ducted acoustic liner technologies developed by NASA over the past 20 years. The ANCF is a low-speed ducted fan test bed for measuring and understanding fan-generated aeroacoustics, duct propagation, and radiation to the farfield. It is considered a low Technology Readiness Level testbed. The international aeroacoustics research community employed the ANCF to facilitate advancement of liner concepts, liner measurement technologies, and for liner code validation. From 1994 to 2016, it was located in the NASA Glenn Research Center’s Applied Aero Propulsion Laboratory. In 2016 the ANCF was transferred to the University of Notre Dame where it is expected to continue to positively impact research in the liner area. This paper summarizes the capabilities and contributions of the ANCF to the field of liner development by documenting its history.
