Abstract
An arrangement to prevent a premature ignition of an active charge, which is to be ignited by means of an adjustable time-delay fuse and is provided for a projectile that is expended from a firing barrel by means of a charge, includes both a mechanical and a pyrotechnical safety element. The ignition path between a first delay element that can be ignited while firing and the active charge of the projectile can be blocked by a barrel probe movable at right angles to the firing direction, and in its position blocking the ignition path can be arrested by an acceleration probe movable counter to the firing direction and, as long as the projectile is located in the firing barrel, by the firing barrel wall. A second delay element which can also be ignited while firing and exhibits a shorter delay period than the first delay element pressurizes the barrel probe with gas pressure in the direction of its end safety position following expiration of its delay period.
