Air Force Boom Event Analyzer Recorder (BEAR): Comparison with NASA Boom Measurement System

摘要

AAMRL and NASA conducted a joint sonic boom test at Edwards AFB to field check the AAMRL Boom Event Analyzer Recorder (BEAR). Sonic boom overpressures were generated over the range of 0.5 pounds per square foot (PSF) to 36 PSF to verify the capability and establish the credibility of the BEAR over its full design range. These booms were simultaneously collected using the AAMRL BEARs and the long-established NASA Analog Sonic Boom Recording Systems. This report documents the results of these tests that show great agreement between the two systems and fully validates the BEAR systems for future Air Force boom measurement programs. This report also shows the AAMRL inverted microphone amount configuration obtains identical results as the flush microphone mount for recording sonic boom events.
