Preliminary Aeroacoustic Measurements of In-Flow Reference Arrays and Sources at ARC
This presentation will review progress in recent testing of in-flow reference arrays and sources for aeroacoustic research testing at NASA aerodynamic centers. The sources were speakers and a multiple air jet source in an aerodynamic fairing, placed in the test section of the Army 7x10 untreated wind tunnel at ARC. The array used was an 8D, 24 element pattern in a similar aerodynamic fairing.
