26793-38 A missile having a super-calibre control-surface system, the fins of which are folded into the missile structure for storage, for transportation, and for launch, when they are locked in this position at the face end, until they are released by a safety system as a function of launch acceleration, when they deploy, is fitted with a compact, functional safety system that releases all the fins simultaneously, but not prematurely, so that they may deploy. To this end, there is a plunger that acts simultaneously in all the fins and which can be displaced axially in the direction of launch relative to these; this plunger only moves into the release position when the missile launch acceleration has diminished. Prior to this, in the opposing direction of displacement, a safety pin is sheared by the plunger or a separate shearing sleeve, said safety pin locking the plunger in the locked position during logistic handling of the missile. |
