Abstract:
1. A device for simultaneous deployment of control surfaces of a projectile, each control surface configured to be pivoted by a motor after deployment of the control surface to ensure piloting, wherein each control surface is held within the projectile, and a first releasable locking element maintains an elastic element in a compressed position, each control surface is deployed towards an exterior of the projectile by expansion of the elastic element, each control surface being deployed by a rotation of each control surface with respect to a control surface support around a deployment axis that is crosswise to a lengthwise axis of the projectile, the lengthwise axis of the projectile including an anterior and a posterior of the projectile, the elastic element interacts with all of the control surfaces to ensure the deployment of all of the control surfaces in relation with slides, the expansion of the elastic element generating a push stress directed along the lengthwise axis of the projectile and exerted on a push plate which transmits the push stress to the slides and to the control surfaces to be deployed, and each of the slides engages, without slipping, with a matching profile integral with a base of the control surface, each of the slides making each respective control surface pivot with respect to the control surface support, the matching profile integral with the base of the control surface being housed within the control surface support.
