An airborne body possessing stabilizing fins or control surfaces, wherein each stabilizing fin is displaceable about an associated bearing axle between a retracted inoperative position and a position of flight in which it is unfolded from the airborne body. An arrangement is associated with each stabilizing fin or control surface, which arrangement is provided for the damping or cushioning of the extending movement of the respective stabilizing fin from the inoperative position into the flying position and for the latching of the stabilizing fin in the flying position, while inhibiting and rebounding of the fin.

Airborne body with stabilizing fins

An arrangement for the unlatching and extension of the stabilizing fins or control surfaces of a projectile, including a power element which is effective in the longitudinal direction of the projectile for pressing a follower against camming or runoff edges located proximate hinged connections at the fin footings, after a latching for the stabilizing fin in the region of their end surfaces has been released. The power element causes a latching crown or ring to be raised away from the end surfaces of the stabilizing fins opposite the force of a spring through the longitudinal movement of a connecting or pusher rod prior to the pusher rod engaging behind the follower and then pressing against the runoff or camming edges.
