Device for simultaneous deployment of the control surfaces of a projectile
First Claim
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, whereineach 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, andeach 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.

Abstract
A simultaneous deployment device for the control surfaces of a projectile for which each control surface is intended to be pivoted by a motor after its deployment to ensure the piloting, each control surface being held within the projectile and deployed towards the exterior of the projectile by the expansion of elastic means, each control surface being deployed by a rotation with respect to a control surface support and following a deployment axis that is crosswise to that of the projectile, wherein the elastic means are common means to ensure the deployment of all the control surfaces, the expansion of the elastic means generating a push stress directed along the axis of the projectile and being exerted on a push plate which transmits the push stress to as many slides as there are control surfaces to be deployed, each slide cooperating without slipping with a matching profile integral with a base of the control surface to make this pivot with respect to its support and first releasable locking means that maintain the elastic means in the compressed position.
