Seth Beaman, a Naval Air Systems Command aeropropulsion test analyst, sets up a high-speed camera, Sept. 1, 2020, in the sea-level test cell SL-1 at Arnold Air Force Base, Tenn. The camera, combined with software, allows for the observation and measurement of vibrations. Beaman is studying the potential for its use as an analysis tool for engine testing.
