Abstract

Stabilization device with deployable fins for artillery projectile intended to be fired into a barrel tube with a launching charge characterized in that each of its fins is arranged in a bent position with the fin body a cavity widely open towards the rear to automatically ensure the deployment of the fin as soon as it comes out of the mouth of the barrel tube due to the expansion of a fraction of the gases under pressure that emanate from the launch charge and have precipitated into said cavity.
