  • Temperature-sensitive disarming element
    Patent number: 3972289
    Abstract: A temperature-sensitive disarming element for a warhead comprising a retang ring for the detonation-lead positioning cup. The retaining ring is made from a material whose characteristic is that its mechanical strength degrades rapidly at a temperature of about 250.degree.-300.degree.F. so that it permits the positioning cup to be blown off in a flame environment. This prevents pressure buildup in the warhead charge, which would lead to detonation of the warhead.
