A wing arrangement, a projectile, a use and a method for deploying a wing blade

The invention relates to a wing arrangement (10) for a projectile (1). The wing arrangement (10) comprising: an elongated wing base (20) configured to be arranged at a circumferential wall (2) of the projectile (1); a wing blade (30) configured to be attached to the wing base (20) along a pivot axis (P) extending along a longitudinal extension of the wing base (20); a deployment arrangement (40) configured to control a pivotal movement of the wing blade (30) around the pivot axis (P) from a folded state to a deployed state. The deployment arrangement (40) comprises a power source (41), a drive block (42) and an elongated drive pin (43). The power source (41) is configured to displace the drive block (42) whereby a distal end (45) of the drive pin (43) slides along a groove (33) in the wing blade (30) so that the wing blade (30) is pivoted around the pivot axis (P) to the deployed state. The invention also relates to a method for deploying a wing blade (30), use of a wing arrangement (10) and a projectile (1).
