Abstract
A dual signature arming mechanism responsive to acceleration to cock a fig pin and responsive to propellant combustion gas pressure to pyrotechnically release a pivotally mounted detonator which rotates into position relative to said firing pin. A plunger restrained by the pyrotechnic release is provided to disable the arming mechanism if the pyrotechnic release is activated before a specific velocity is reached.
Claims9
In a combination of an arming mechanism, a firing pin and a detonator, said detonator being pivotally mounted to said mechanism to rotate in a first plane, said mechanism comprising:
- first means responsive to the acceleration forces on said arming mechanism for biasing said detonator to rotate from a first position to an armed position;
- second means adjacent said detonator for initially detaining said detonator from moving to said armed position;
- and
- third means connected to said second means and pyrotechnic means for moving said second means out of said first plane to allow said first means to rotate said detonator to said armed position.
In a combination of an arming mechanism, a firing pin and a detonator, said arming mechanism comprises:
- first means responsive to the acceleration force of said arming mechanism for biasing said detonator to move from a first position to an armed position;
- second means adjacent said detonator for initially detaining said detonator from moving to said armed position;
- third means including a pyrotechnic wire connected to said second means for maintaining said second means adjacent said detonator;
- and
- fourth means for actuating said pyrotechnic wire to release said second means and allow said first means to move said detonator to said armed position.
