Abstract (en)
[origin: EP0463974A1] The subject of the invention is a safety and arming device for ammunition, capable of ensuring the alignment of the pyrotechnic chain and of occupying two different positions, a first in which the detonation of the ammunition is prevented and a second in which detonation is transmitted. It consists of a chain of interruption means 3 having a passage 2a made along a diameter perpendicular to the directions of the stresses undergone by the ammunition during the operational phases and incorporating or not a relay composition 2 actuated along a helical path of an angle alpha in order to bring the passage 2a from the first position, called the safety position, in which it is arranged in a plane substantially orthogonal to the axis of alignment of the pyrotechnic chain, into the second position, called the arming position, in which it is aligned with the axis 6 of the chain. The helical movement is the combination of a translational movement and of a rotational movement alpha through approximately 90 DEG and is executed in three successive phases, a first phase A, during which, above all, a translational movement and a low rotation of between 0 and 15% of the angle alpha are obtained, then in a phase B of high rotation of between approximately 15 and 85% of the angle alpha , and finally in a phase C, above all a translational movement and a low rotation into the armed position. The invention is used for military charges. <IMAGE>
