Abstract:
1. A projectile body intended to evolve in a fluid, comprising: at least two housings disposed inside said body capable of communicating with an exterior of said projectile body via an opening; and at least two control surfaces configured to deploy by moving rectilinearly in a radial direction, said control surfaces being disposed prior to their deployment inside the respective housings, wherein said housings communicate at their intersection point, said housings being blocked by a sealing device preventing any fluid from the exterior of said projectile body from passing through said housings when said control surfaces are deployed, wherein said sealing device incorporates tubular sectors positioned coaxially to said projectile at the intersection of the different control surface of said housings, said tubular sectors being integral with said projectile body and in contact with each other by at least one generating line when said control surface is deployed, contact generating line that is in the same plane as that of said deployable control surfaces, such that contact generating line forms an airtight seal, said tubular sectors being in contact with said deployable control surfaces when said control surfaces are in their retracted position.
