    摘要: An apparatus and method for safing and arming a projectile is disclosed. The apparatus utilizes an out of line rotor configuration where the detonator is mounted in the rotor. In the safe position, the detonator is out of line with an explosive lead. The rotor is locked out of line with two independent locks. One lock is removed at gun launch setback and the second lock is removed at the time of arming, when a preselected environment is detected by electronics and safe separation is assured. The first lock includes a spring and a weight where the weight is biased in a position to prevent the rotor from moving to an in line position. At setback, the g-forces act on the weight to overcome the spring and the weight is removed from the path of the rotor. Once the selected environment is sensed and safe separation is established the electronic input to arming is permitted. A primer is ignited to remove the second lock shear tab and rotate the rotor to the armed position where the detonator is aligned with the explosive lead. A firing circuit can then be employed to ignite the detonator causing propagation of hot gases and particles to the explosive lead which ignites the warhead explosive/propellent of the projectile.
