Abstract

Stabilizing fin assembly for projectile (2) designed to be discharged from a barrel (1) by means of propellant charge gases from a propellant charge (5). During their passage through the barrel the fins (8) are in the retracted, on-edge position, and arranged to be extended when the projectile (2) leaves the barrel (1). With the fins in the retracted position the space (13) between the fins (8) is at least partially open to the rear during passage through the barrel, so that the propellant charge gases have acces to the said space (13). The space (13) is exhausted of propellant charge gases when the projectile leaves the barrel (1), and the propellant charge gases as they rush out pass along the guide surfaces of the fins (8), causing a frictional force which jerks the fins (8) to the extended position. In some embodiments the guidance mechanism is also provided with a further space (11, 18, 18a) under the edge (12) of the fins (8), which during passage through the barrel is filled with propellant charge gases which exert an extra extending force against the edge (12) of the fins (8).
