FOAMED SULFUR FOR AIRDROP CUSHIONING

Abstract

Investigation of foamed sulfur as an improved energy dissipator to prevent damage to military equipment in airdrop applications has shown this material to have such desired project target characteristics as: A capacity for withstanding temperature extremes of -65 to +125F in storage and during use, and being unaffected by direct contact with water; Proving an approximately rectangular force-deformation curve to 80 percent deformation when the forces are dynamically applied at initial impact velocities ranging from 20 to 46 fps (46 fps was the highest impact velocity actually used); Limiting rebound energy or resilience to less than 5 percent of total energy dissipated to 80 percent deformation; Having a material cost of less than $0.15/1000 ft-lb of energy dissipated.
