Measurement and Evaluation of Blast Overpressure During F-15A Crew Station Vulnerability Assessment Test
Abstract
From March 1991 to May 1991 blast overpressures were measured from 21 different projectiles striking a section of the F-15 fuselage to assess potential crew hazards. The velocity of the fired projectiles ranged from 1500 ft/sec to 5000 ft/sec and the lowest overpressure which was recorded was 7 PSF or 145 dB and the highest level recorded was 1875 PSF or 194 dB sound pressure level (re 20 u Pa). Time histories for each recording and the sound exposure spectrum levels as a function of frequency are presented. A hearing damage risk assessment was made in the context of the Air Force hearing damage risk criteria (AFR 161-35) and laboratory data regarding the effects of high level impulses on man.
