Bomb Survivability in Fire Program
Abstract
The bomb survivability in fire program was initiated to determine the hazards that exist when bombs are exposed in a carrier flight deck fire (fast cook-off) and to investigate methods of minimizing or eliminating these hazards. All M117, AN-M65 and MARK 80 series bombs employed in the program were exposed in a JP-5 jet fuel fire environment that simulated a flight deck conflagration. The severity of reaction, time to reaction and, when pertinent, internal time- temperature information were obtained. Also determined from the program were: (1) relationship of bomb size, explosive load and fuzing configuration to cook- off time and severity of reaction, (2) influence of aircraft structure on bomb cook-off time and severity of reaction, (3) likelihood of bomb cook-off after abbreviated heating periods, (4) adequacy of water and aqueous film forming foam (light-water) as cooling measures for preventing bomb cook-off, and (5) effect of elevated temperature on bombs subjected to accidental ejection from parked aircraft or other accidental drops on board ship. The results of supporting tasks investigating quick fire starting, wind effects, internal thermocouple design, inert filler, water and light-water rates apparatus design, ejection cartridge cook-off, evaluation of fire retardant paints and computer studies and analysis are also presented.
