Abstract:
1. A safety and arming unit for a spinning projectile fuze, said fuze including a fuze body ( 12 ) and a bearing body which define a hemi-spherical contact therebetween, a spherical rotor ( 18 ) being rotatably mounted in said cutout, a detonator ( 20 ) being arranged in said rotor ( 18 ), said rotor ( 18 ) possessing a recess ( 22 ) into which a bushing ( 24 ) projects in the safe position of the safety and arming unit ( 10 ) prevents the rotor ( 18 ) from rotating, the rotor ( 18 ) having at least one recess ( 62 ) into which a radially oriented transverse bolt ( 64 ) projects in an interlocking manner in the safe position of the safety and arming unit, at least one transverse bolt ( 64 ) being held in the recess ( 62 ) in the safe position by an acceleration bolt ( 70 ) and a first spring element ( 72 ), which are axially oriented, and a second spring element ( 76 ) being connected to the at least one transverse bolt ( 64 ), said rotor ( 18 ) being prevented from rotation into an axial armed position thereof until release of said bushing ( 24 ) into movement away from said rotor ( 18 ) by a second arming system.
