NASA’s Glenn Research Center employs a suite of sophisticated instruments for detailed analysis of airflow and acoustic properties within aerospace systems. Specifically, researchers utilize particle image velocimetry, hot wire anemometry, and Raman spectroscopy to capture precise measurements. Furthermore, the center leverages microphone technology incorporating phased array configurations alongside continuously rotating rakes for comprehensive sound assessments. This instrumentation is crucial as it directly supports the global aviation noise reduction community's efforts. Data generated by these experiments at NASA GRC are vital for validating theoretical models and refining noise prediction software used worldwide.
