Abstract
A safety and arming device for a spin-stabilized explosive projectile, said device incorporating a screen obstructing a transmission channel linking a detonator and a pyrotechnic relay, said screen comprising two half-screens able to move with respect to one another and transversally with respect to said channel, said two half-screens obstructing said channel when contacting one another, wherein said two half-screens are able to slide in a bore hole carried by a rotor coaxial to said projectile, said rotor is able to pivot on the axis of said projectile and carries said channel, said two half-screens locked into the position obstructing said channel by at least two locks, a first lock or inertial lock which retracts when said projectile is fired and a second lock or centrifugal lock formed by a spiral spring surrounding an external cylindrical surface of said rotor and applied against the ends of said half-screens.
