Abstract
A safing and arming device for a munition fuze operates without the use of stored energy. The safing and arming device is controlled by a solenoid rotating a rotor and shutter in a ratchet fashion. As the shutter is rotated, a detonating device is brought into position over an explosive lead charge. The design of the rotor and shutter ensures that the detonator is not aligned with the lead charge until after several safety steps have been completed, after which the shutter quickly arms the fuze. Energy is generated for fuze arming during the completion of the safety steps. The design of the safing and arming device minimizes power requirements for safing and arming the fuze.
