摘要： A projectile to be fired from a weapon barrel includes a projectile body and a plurality of stabilizing wings circumferentially distributed about a rearward portion of the projectile body. A pin pivotally attaches each stabilizing wing to the projectile body for pivotal motion about a pivot axis to assume a folded state and an outwardly pivoted, deployed state. In the folded state of the stabilizing wings the center of gravity of the respective stabilizing wings is at a greater radial distance from the longitudinal axis of the projectile body than the pivot axis. A gliding body is releasably mounted on each stabilizing wing. Each gliding body has a wing-shaped extension for contacting an inner surface of the barrel in the folded state of the stabilizing wings as the projectile travels in the barrel upon firing. In the deployed state of the stabilizing wings the wing-shaped extensions are exposed, during the flight of the projectile, to an air stream causing the gliding bodies to be stripped from the stabilizing wings.
