Blast overpressure and survivability calculations for various sizes of explosive charges

P. W. Gibson

Sayı: NATICK/TR-95/003, 1994/11

Blast overpressures and durations were calculated for several different explosive charge sizes. The charge sizes range froin 1ounce of TNT to 32 ounces of TNT. The distance from the charge ranged from Ito 3 feet. When the blast calculations were compared to human blast tolerance limits, it was found that the blast exposures mostly fell in between the 1%survival limit and the threshold of lung damage. This probably means that a heavily-protected explosive ordnance disposal technician, supplied with a rigid enclosed thoraco-abdominal protector, may be able to survive the air blast effects at these distances. Note that these calculations only pertain to direct air blast effects and ignore fragments and thermal effects entirely.
