Abstract:
1. A mechanism configured to transition an explosive device from a SAFE arrangement to an ARMED arrangement, comprising: a first firing pin configured to move along a longitudinal axis in response to a first deceleration force; a delay primer configured to be operated by the first firing pin moving along the longitudinal axis, the delay primer being configured to generate a pressure force at an end of a delay period; a second firing pin configured to move along the longitudinal axis in response to the pressure force at the end of the delay period and a second deceleration force that is greater than the first deceleration force; a rotor configured to move between first and second radial positions with respect to the longitudinal axis, the first radial position corresponding to the SAFE arrangement, and the second radial position corresponding to the ARMED arrangement; and a detonator configured to be operated by the second firing pin moving along the longitudinal axis when the rotor is in the second radial position, and the detonator being configured to be inoperable when the rotor is in the first radial position.
