Definitions
- the present invention relates to a guided projectile whose nose is provided with a sleeve serving as a mounting interface for a guidance system.
- the geometry of these bombs and their mounting interface significantly reduces their penetration performance.
- to allow the integration of guidance systems to the NATO standard, such as a laser guidance system, a gyroscope or an accelerometer it is necessary that these bombs have an interface compatible with military standards.
- the machining of this interface in the mass of the projectile is however difficult and expensive.
- the rupture of the interface during the impact occurs unpredictably and irregularly, which reduces the penetration performance.
- the current guided projectiles are not entirely satisfactory.
- An object of the present invention is therefore to solve the problems mentioned above with a solution that is simple to implement, reliable and inexpensive.
- the invention proposes to report a rupture piece on the nose of the projectile to maximize the penetration performance while enjoying the accuracy offered by NATO standard guidance systems.
- the present invention relates to a guided projectile comprising:
- the guided projectile according to the present invention may further comprise at least one
- the cylindrical connecting portion is located between a front ogival portion and a rear ogival portion of the nose and connects these two parts continuously;
- the cylindrical connecting portion carries an external thread cooperating with an internal thread formed in a rear portion of the cylindrical sleeve;
- the cylindrical sleeve has a flange before extending it continuously outwards
- the cylindrical sleeve has, at its front flange, an internal thread for receiving the guidance system when the projectile is in use condition and a protective cap when the projectile is stored;
- the cylindrical sleeve is made of a low-resilience material, for example a fragile steel; and the nose is made of a material with a high elastic limit, for example a steel.
- FIG. 1 is a side view showing, separated from one another, a projectile and a sleeve according to the present invention
- FIG. 2 is an enlarged view of the front portion of the projectile of FIG. 1;
- Figure 3 is a longitudinal sectional view of Figure 2;
- FIG. 4 is an enlarged side view of the front portion of the projectile provided with the sleeve; and - Figure 5 is a sectional view of Figure 4.
- FIGS 1 and 2 schematically show a guided military projectile 1, such as an aerial penetration bomb.
- the guided projectile 1 comprises in particular a cylindrical tubular body 10 terminating at the front by a nose 20 having a generally ogival shape. More specifically, the nose 20 comprises a front nose 21 having a first profile and ending with a penetration point 22, and a rear nose 23 having a second profile different from the profile of the nose before 21.
- the double-pointed form of the nose nose 20 thus facilitates the penetration of the guided projectile 1
- An intermediate connecting zone 25 is situated between the front nose 21 and the rear nose 23 and connects them in a continuous manner.
- the intermediate zone of connection 25 is constituted by a cylindrical part provided with an external thread 26.
- Guided projectile 1 also includes a cylindrical sleeve 30 serving as a mounting interface for a NATO standard qualified guidance system (not shown), such as a laser guidance equipment cooperating with a global satellite positioning system.
- a NATO standard qualified guidance system such as a laser guidance equipment cooperating with a global satellite positioning system.
- the cylindrical mounting sleeve 30 is removably attached to the nose 20 of the guided projectile 1. More specifically, the cylindrical sleeve 30 has a rear portion 31 provided with an internal thread 32 for cooperating with the external thread 26 of the part cylindrical connecting 25 of the nose 20.
- the cylindrical mounting sleeve 30 also has a flange-shaped front portion 33 extending continuously outwardly.
- the front portion 33 of the cylindrical sleeve 30 is flared so as to oppose the maximum surface area to the impact and to concentrate the stresses in specific zones. The concentration of stresses within the cylindrical mounting sleeve 30 thus causes the destruction thereof and facilitates the subsequent penetration of the guided projectile 1.
- the front flange 33 has an internal thread 34 intended for fastening the NATO standard guidance system in the conditions of use of the projectile 1 (for example when it is integrated with a military vehicle such as an airplane, a boat, a tank or a submarine), or a protective cap (not shown) when the projectile 1 is stored before integration.
- the cylindrical mounting sleeve 30 is made of a low-resilience material, for example a brittle steel, so as to reduce the energy dissipation during its destruction.
- the body 10 of the projectile 1 according to the present invention is made by forging in a high-elastic, high-density and high-hardness material, for example a low-alloy steel having has undergone a suitable hardening treatment, such as quenching or carburizing.
- a suitable hardening treatment such as quenching or carburizing.
- the cylindrical mounting sleeve 30 breaks into pieces because of the fragility of the material constituting it.
- the destruction of the guidance system also occurs at this time, without affecting the penetration or guidance of the guided projectile 1.
- the nose 20 is made of a rigid material and a part of absorbed stresses causes the destruction of the cylindrical sleeve 30, the guided projectile 1 can penetrate deeper into the target.
- the present invention thus proposes a guided projectile 1 equipped with a removable cylindrical sleeve 30 which makes it possible both to easily mount a guidance system on its body 10 and to reduce the dissipation of energy during an impact against a hard target. .
- the removable attachment of the cylindrical mounting sleeve 30 on the nose 20 of the projectile 1 can be made in another way than described, for example by axial clipping force or using a bayonet system.
- the invention applies to any type of guided military projectile, such as a missile, a bomb, a penetrating charge, etc.
- the mode of propulsion, as well as the place from which the projectile is sent and the place to which it is directed, are of little importance.
- the guided projectile 1 according to the present invention can be launched from the ground (tank, artillery battery), from the sea (cruiser, submarine) or in the air (bomber, fighter), and the target can to be on land, at sea or in the air.
- the profile of the rear warhead 33 may be identical to the profile of the nose before 31, that is to say that the two warheads can follow the same curvature being an extension of one another.
- the cylindrical body may be solid or hollow so as to enclose an active or inert material.
- the sleeve may be made of a composite material or a metal alloy having the same mechanical characteristics as those of the steel described.
