Abstract: A securing and arming device has an operating body. Prior to an arming time, this operating body is secured in a position of rest on a support device, namely by means of a securing element, which here is in a securing position. If the securing element is moved into a release position, it releases the operating body to make a movement in relation to the support device. After the arming time, the trigger body is in an operating position by means of a rotating movement in relation to the support device. A delay element is designed to be driven in the course of the rotating movement of the trigger body and to delay the rotating movement of the trigger body. The trigger body and the delay element are arranged inside each other so that they constitute an outer wheel shaft-free wheel and an inner wheel shaft-free wheel. The two wheels have parallel geometric wheel axes and define a ring-like gap.

Abstract: A securing and arming device (10) has an operating body (20). Prior to an arming time, this operating body (20) is secured in a position of rest on a support device (12), namely by means of a securing element (30), which here is in a securing position. If the securing element (30) is moved into a release position, it releases the operating body (20) to make a movement in relation to the support device (12). After the arming time, the trigger body (20) is in an operating position by means of a rotating movement in relation to the support device (12). A delay element (22) is designed to be driven in the course of the rotating movement of the trigger body (20) and to delay the rotating movement of the trigger body (20). The trigger body (20) and the delay element (22) are arranged inside each other so that they constitute an outer wheel shaft-free wheel and an inner wheel shaft-free wheel. The two wheels have parallel geometric wheel axes and delimit a ring-like gap.

Abstract: A projectile, having a casing, a projectile base, which closes the casing off at the rear, a receiver coil for receiving electromagnetic signals, an energy source which is put into contact with the receiver coil, and a logic module. The casing is made from a plastic material, at least in the area of the rear.

Abstract: In connection with a projectile, the effective substance (4) is designed as a projectile core (3), which is held in place by a propulsion reflector sheath (1) and a propulsion reflector back (2). The data reception coil (13) and the power supply (14) are arranged in the propulsion reflection back (2), while the remaining elements (9, 10, 11, 12) of the programmable time fuse (8) are installed in the projectile core (3, 25). Predetermined breaking points are provided in the propulsion reflector sheath (1) and the propulsion reflector back (2), so that following the firing of the projectile, the propulsion reflector sheath (1) and the propulsion reflector back (2) with the data reception coil (13) and the power supply (14) are separated, and only the projectile core (3) with the remaining elements (9, 10, 11, 12) of the programmable time fuse (8) alone continue to travel.
