Abstract:
Arming of a detonator carried within a tube-launched projectile is delayed n accordance with an operational program of a safety-arming system initiated by simultaneous and independent detection of projectile propulsion involving pressure generated by an activated projectile propelling motor and inertial forces accompanying acceleration of the projectile during launch. Operating energy necessary to complete the operational program, terminated after the projectile is launched, is stored within the projectile during launch in response to said generation of pressure by the activated propelling motor.
