ABSTRACT:
In a rifled missile having a primer tube or firing channel, a safety device adapted to coact with a percussion fuse. The safety device is disposed in the missle transversely across the primer tube between the impact-sensitive primer and a booster charge. The primer tube axially extends from the impact-sensitive primer to the booster charge. The safety device includes a blocking disc and a biased tape-reel surrounding the blocking disc and bearing against it. The tape-reel is adapted to unwind when under the influence of a predetermined centrifugal force to thereby release the blocking disc which is then freed to turn oppositely relative to the rotary direction of the missile due to the influence of a predetermined inertial force to thereby unblock the primer tube.
