Safety-arming system for launched projectiles

In a safety system carried by a projectile having a detonator and control means responsive to operating energy applied thereto enabling the detonator, means responsive to launching of the projectile for storing the operating energy therein and means operatively connected to the control means for delaying the application of the operating energy thereto from the storing means in response to acceleration of the projectile during said launching thereof.

A safety system adapted to be installed in a projectile having a detonator to which an ignition path is established, said system including switch means for maintaining an interruption in said ignition path during launching of the projectile, means for storing operating energy during said launching of the projectile, control means in which the switch means is mounted for removal of said interruption in response to release of the operating energy after completion of said launching of the projectile, a housing removably inserted into the projectile and condition indicating window means mounted by the housing for visual exposure of the control means therethrough.

A safety system adapted to be installed in a projectile having a detonator to which an ignition path is established, said system including switch means for maintaining an interruption in said ignition path during launching of the projectile, means for storing operating energy during the launching of the projectile, control means in which the switch means is mounted for removal of said interruption in response to release of the operating energy after completion of said launching of the projectile, said control means including at least two different devices for independently detecting propulsion of the projectile during said launching thereof, interlocking means displaceable between active and inactive positions for respectively blocking and enabling said removal of the interruption in the ignition path by the control means and means responsive to detection of said propulsion of the projectile by both of the two detecting devices for enabling displacement of the interlocking means to the inactive position.

A safety system adapted to be installed in a projectile having a detonator to which an ignition path is established, said system including switch means for maintaining an interruption in said ignition path during launching of the projectile, means for storing operating energy during said launching of the projectile, control means in which the switch means is mounted for removal of said interruption in response to release of the operating energy after completion of said launching of the projectile, said control means including a slider displaceable to an arming position in which the switch means is actuated to remove the interruption in the ignition path, piston means responsive to said launching of the projectile for displacement from a safe position to load the storing means with the operating energy and acceleration responsive means for delaying said displacement of the slider to the arming position by the operating energy from the storing means following said loading thereof by the piston means.
