Machine-written summary, checked against the sources below
Research teams at NASA Glenn Research Center use instrumentation such as particle image velocimetry, hot wire anemometry, Raman spectroscopy, phased-array microphones, and continuously rotating rakes to measure airflow and sound. Data from these experiments is used by the global aviation noise reduction community to validate theory and noise prediction software.
To measure airflow and sound, research teams at the NASA Glenn Research Center use special instrumentation like particle image velocimetry, hot wire anemometry, Raman spectroscopy, microphones in phased arrays or continuously rotating rakes. The global aviation noise reduction community relies on data from NASA GRC experiments to validate theory and noise prediction software. Rotating Rake […]
