Abstract
A safe-arm device for use in a fuel-air explosive munition carried by an craft. The device has a housing having an environmental seal which is separated from the housing upon munition release to form a seal opening, a pressure probe for obtaining static and dynamic air pressure and extending through the seal opening when deployed, a piston and rod which is driven upon sensing of a sufficient differential air pressure between the static and dynamic air pressure probe, a safety lock which locks a pyrotechnic rotor and which disengages upon full extension of the piston rod, and an arming spring which is compressed by extension of the piston rod and which drives the pyrotechnic rotor for rotation against a mechanical escapement device thus providing for a timed rotation. The pyrotechnic rotor has two explosive wheels, each having switched detonators and upon receipt of electronic signals two explosive trains with a controlled time delay therebetween are initiated.
