This invention relates to a penetrating projectile, particularly an anti-infrastructure penetration bomb. The invention also relates to a penetration method applied to the above mentioned projectile. The penetrating projectile includes an inner tube inside which a perforating projectile is placed comprising at least one body provided with a pyrotechnic charge and a propulsion body, the body of the perforating projectile being ejected outside the tube by firing the propulsion body; and a system for controlling firing of the propulsion body before the impact of the penetrating projectile on a target. The invention is particularly applicable for passing through very thick walls made of a non-metallic material for example such as concrete.

1. A penetrating projectile, comprising: a body;an inner tube including a perforating projectile inside the inner tube,wherein said perforating projectile includes a body having a pyrotechnic charge; andat least one propulsion body that is entirely arranged behind the body of said perforating projectile, the body of the perforating projectile being ejectable outside the inner tube by firing said propulsion body;a system for controlling firing of the propulsion body before the impact of the penetrating projectile on a target; anda pyrotechnic charge placed between the body of the penetrating projectile and the inner tube,wherein the inner tube includes at least two sections with different calibres, one of the sections with the smallest calibre being oriented towards the output from the tube, the body of the perforating projectile being adapted to the output calibre of the tube, the propulsion body jamming at the transition between the two sections during ejection of the body of the perforating projectile. 2. The projectile according to claim 1, wherein the perforating projectile comprises a system configured to determine a position of the perforating projectile inside the target as a function of time, and to trigger detonation of the pyrotechnic charge of the perforating projectile at a predetermined instant. 3. The projectile according to claim 2, wherein the system of the perforating projectile is configured to determine the position of the perforating projectile starting from a deceleration level characteristics in the material from which the target is made and a velocity at the point of impact on the target. 4. The projectile according to claim 2, wherein the perforating projectile comprises an electronic module including the system that is configured to determine the position of the perforating projectile inside the target, the electronic module also controlling priming of the pyrotechnic charge. 5. The projectile according to claim 4, wherein the electronic module of the perforating projectile is placed on the support. 6. The projectile according to claim 1, wherein the body of the perforating projectile is fixed to the propulsion body by pins, andthe propulsion body includes a pyrotechnic charge thereby the propulsion body is adapted to be fired and the perforating projectile is adapted to be ejected outside the inner tube. 7. The projectile according to claim 1, wherein a primer relay is located inside the pyrotechnic charge of the perforating projectile. 8. The projectile according to claim 7, wherein the perforating projectile comprises a support closing the space behind the pyrotechnic charge of the perforating projectile, said support including a striker facing the primer relay. 9. The projectile according to claim 1, wherein the system for controlling firing of the propulsion body of the perforating projectile comprises an electronic module and at least an ignition chip, an electric signal being sent from the electronic module to the ignition chip through an electrical link. 10. The projectile according to claim 9, wherein the electronic module is toroidal in shape and is placed inside a base closing the body of the projectile. 11. The projectile according to claim 1, wherein said body of the penetration projectile has a symmetry of revolution and has an axis that is coincident with a center line of the inner tube. 12. A method for penetration of a penetrating projectile according to claim 1 inside a target, wherein the perforating projectile is ejected from the tube by firing the propulsion body when the projectile is at a given distance d from the target; andsince the perforating projectile penetrates into the target before the projectile, the perforating projectile detonates inside the target by firing the pyrotechnic charge to create an orifice through which the body of the penetrating projectile passes. 13. The method according to claim 12, wherein the perforating projectile detonates in a center of the target. 14. The method according to claim 12, wherein the target is a concrete wall. 15. A penetrating projectile, comprising: a body;an inner tube inside which a perforating projectile is placed, said perforating projectile comprising at least one body provided with a pyrotechnic charge, the body of the perforating projectile being ejected outside the inner tube by firing a propulsion body formed behind the body of the perforating projectile;a system for controlling firing of the propulsion body before the impact of the penetrating projectile on a target; anda pyrotechnic charge placed between the body of the penetrating projectile and the inner tube,wherein the inner tube includes at least two sections with different calibres, one of the sections with the smallest calibre being oriented towards the output from the tube, the body of the perforating projectile being adapted to the output calibre of the tube, the propulsion body jamming at the transition between the two sections during ejection of the body of the perforating projectile. 16. The projectile according to claim 15, wherein the transition between the two sections is in the form of a cone such that the casing of the propulsion body is welded onto the cone by friction.
