Description

The The invention relates to a cargo projectile with one of a projectile casing wrapped cargo space in which an interceptor to the Intercepting enemy missiles is arranged.

such Cargo projectiles are in particular using large caliber Weapon systems for protecting objects against enemy missiles used, for which the cargo projectiles provided with an intercepting element are from the cargo hold of the cargo projectile into an intercept position is brought in the trajectory of the enemy missile, to detonate them by a collision or at least disturb their trajectory. To determine the time and the location for the application of the interceptor the enemy missiles before the launch of the cargo missile by means of known methods sensory or radar-technologically located and determines the further trajectory of the missile.

In Dependence of the ascertained trajectory becomes the weapon system aligned and the cargo missile towards the trajectory of the shot down enemy missile. After the shooting of the cargo projectile becomes the intercepting element in a few kilometers Distance to the object to be protected from the inside of the Cargo bullet transported out and in a intercept position in the determined trajectory of the enemy missile brought. When striking the enemy missile on the intercepting element whose detonator is activated, so that the missile at a safe distance to the protected Object detonated or at least disturbed the trajectory of the missile and this crashes, leaving the missile no danger to the object to be protected.

When The problem with this type of cargo projectile is the controlled one Application of the interception element within a small time window during flight of a cargo projectile. At the cargo floors These are spin-stabilized projectiles, with one revolution rotate up to 16,000 rpm, causing difficulty in deployment prepares the interception elements.

task The invention is, in a cargo projectile of the aforementioned Type to improve the output of the interceptor.

These The object is achieved according to the invention that the intercepting element in a relation to the projectile casing over housed at least one bearing element rotatably mounted cargo container is.

By the accommodation of the interceptor in a freight container, the opposite to the projectile casing which was set in rotation during firing a bearing element is rotatably mounted, arise different rotational speeds of the outer Projectile shell and the inside freight container, which due to its inertia at launch does not is set in the same rotation as the projectile shell of the cargo projectile. In this way results in a lower Rotation speed of the freight container and thus of the interceptor, which a controlled clamping of the interceptor under the influence of centrifugal force allowed.

Of constructive advantage is an embodiment, according to which the interception element is designed in the manner of a network. As mesh materials are particularly highly tear-resistant materials, such as aramid fibers, and in particular the product marketed by Dupont under the trade name KEVLAR ^® material into consideration.

Advantageous for a controlled clamping of the interception element in the Abfangstellung is an embodiment, according to which the interception element is provided in its peripheral areas with weights. Under the influence the centrifugal force due to the rotation of the intercepting element is with Help the weights reach a rapid spread.

In Another embodiment is proposed that the projectile casing over a floor is closed, the formation of a discharge opening detachable from the projectile casing for the intercepting element is. The detachment of the soil, for example, by blowing off done, including a corresponding explosive charge provided in the ground area can be.

Further is with a view to a controlled application of the interception element proposed that a dispensing element connected to the interception element is, which accelerates the Ausbringvorgang. In this context is further proposed that the dispensing element in the manner of a Bremsschirms is designed. The generated over the brake screen Braking force can be transmitted as traction on the interceptor which pulls it quickly out of the cargo container interior becomes.

It is also proposed with regard to a controlled application of the intercepting element that the projectile casing has an opening of an air inlet, via which an air stream can be guided into the interior of the freight container. Advantageously, the opening in the region between the projectile nose and the cargo space is arranged. For discharging the intercepting element, the opening of Luftein Leaves are opened during the flight, whereby an air flow into the interior of the freight container is created, which is available for the application of the interceptor element. It is also possible to provide a plurality of air inlet openings, for example in a radially symmetrical arrangement with respect to the axis of the projectile. The opening of the air inlet can take place via a blast, which takes place in an advantageous embodiment simultaneously with the blasting of the soil.

In In this context, it is further proposed that the freight container a piston which is formed so that it is under the influence of an air flow for the application of the intercepting element moved against the direction of flight of the cargo projectile. To this Way, the interception element from the inside of the cargo projectile controlled pressed outward.

Further it is suggested that the piston on its side facing away from the air intake Side is provided with a fastener on which the Dispensing element is connected.

Further is provided that the Ausbringelement via a swirl decoupling element is attached to the fastener, so that the rotational movement the fastener or the freight container not on the Dispensing element transmits, if this the cargo space has left.

Further is provided that the piston via a swirl decoupling element and / or a strain relief element on the front side of the freight container or the projectile casing is tied. Also this configuration serves to rotate the bullet casing from that of the Decoupling freight container. About the strain relief element Furthermore, an overload of the application of the Intercepting elements in the power flow ropes, strands, etc. avoided.

Farther It is envisaged that the interceptor in a zig-zag fold is placed around the mantle of the cylinder. This way results a defined storage of the interceptor in its transport position. The interceptor may, for example, by machine in such Folding can be stored before the freight container in the projectile casing is used, thereby increasing the risk of malfunction reduced due to assembly errors.

After all It is proposed that the freight container take the form of a one-sided having open cylinder.

Further Details and advantages of the invention Cargo projectiles are subsequently described with the aid of the appended Drawings of an embodiment explained. Show:

In 1 is in schematic representation one in front of an enemy missile 50 , For example, an artillery projectile, a rocket, a mortar projectile, etc., to be protected object in the form of a spatially extended camp 100 shown with square base. At the corners of the camp 100 there is one device each 101 for firing a cargo projectile 1 in the trajectory F _{1 of} the enemy missile 50 to the danger posed by this for the object to be protected 100 ward.

In the 2 closer device shown 101 has a large caliber artillery gun 102 on, over which the cargo projectiles 1 to catch enemy missiles 50 are verschiessbar. The device 101 also has a first locating device 103 , a second locating device 104 , a measuring device 105 , a signal transmission unit 106 as well as a fire control computer 107 on. The artillery gun 102 , the locating device 104 , the measuring device 105 and the signal transmission unit 106 are via data lines 108 with the fire control computer 107 connected.

For reliable detection and defense of enemy missiles 50 are the locating device 103 and the artillery gun 102 spatially close to dislocate.

About the locating device 103 becomes the approaching enemy missile 50 elucidated, including both optronic sensors and radar devices can be used. The over the locating device 103 collected data are sent to a second location facility 104 transmitted for the purpose of target tracking. This will be the position data of the missile 50 as so-called track data continuously determined. By means of the fire control computer 107 the calculation of a Feuerleitlösung, due to which the artillery gun 102 automatically aligned and the cargo floor 1 in particular automatically fired at the calculated time. Also, several devices can simultaneously 101 a concentrated fire hit with cargo bullets 1 against the approaching missile 50 to lead.

With the help of the measuring device 105 is the speed of the cargo projectile 1 measured and the corresponding data to the fire control computer 107 transmitted. From this a corrected Feuerleitlösung is calculated and a time to transfer the cargo projectile 1 determined in its defensive position. At this time, the signal transmission unit is being used 106 transmits a radio signal to the cargo floor, through which the cargo floor 1 in a distance range of a few kilometers before the calculated trajectory end or the planned impact point of the missile 50 is transferred in still closer to descriptive manner in the defensive position. Details of such a control and calculation method are described, for example, in German patent applications no. DE 10 2007 007 404.4 and DE 10 2007 007 403.6 described.

The cargo projectile 1 flies from the artillery gun 102 along the firing trajectory F ₂ in the direction of the missile to be defended 50 , recognizes the correct distance to the missile 50 and goes into a defensive position, in which the interception element 7 in the calculated trajectory F _{1 of} the enemy missile 50 located. The transition of the cargo projectile 1 in its defensive position can be initialized in various ways, for example on a the enemy missile 50 detecting proximity sensor or by means of a transmitted at the right moment radio signal. The cargo projectile 1 is in the range of the calculated point of intersection S of the two trajectories F ₁ and F _{2 transferred} to the intercept position.

In 3 shown is a view of the cargo floor 1 in its defense position. In this position, the interceptor is located 7 in the trajectory F _{1 of} the enemy missile 50 so that the enemy missile 50 on the interception element 7 meets.

At the interception element 7 it is a net-like structure behind the projectile shell 2 is arranged hanging in a kind of drag arrangement. The enemy missile 50 gets from the interceptor 7 intercepted, and braked abruptly by the impact. Due to the impact of the enemy missile 50 on the interception element 7 its detonator can be activated so that the enemy missile 50 detonated in flight. For missiles 50 without impact fuse is due to the collision with the net-like interception element 7 the trajectory F ₁ disturbed or changed such that the impact of the highly delayed missile 50 no more threat to the object to be protected 100 is represented and rendered harmless, for example by crash. Due to the high speeds of both the enemy missile 50 as well as the cargo projectile 1 It is of great importance that the unfolding of the interception elements 7 reliably and within a short time window defined.

Details of the cargo projectile 1 and the operations during its transfer from the transport or cargo position to the intercept position are subsequently with the aid of 4 and 5 described, in 4 the transport position and in 5 the intercept position is shown.

In 4 is the inner structure of the cargo projectile 1 shown schematically. The cargo projectile 1 is composed of a projectile shell 2 , which on its side remote from the projectile tip on a bullet bottom 3 is closed and in this way a closed cargo space 4 envelops. Inside the cargo hold 4 is an essential element of the cargo projectile 1 a freight container 5 arranged in which the intercepting element 7 folded is stored. The freight container 5 is about storage elements 6 opposite the projectile shell 2 rotatably mounted, so that when leaving the barrel of the artillery gun 102 on the projectile shell 2 transferred twist D ₁ due to the inertia of the freight container 5 is not completely transferred to this, ie the freight container 5 one compared to the projectile shell 2 lower, for the deployment of the interception element 7 has a lower rotational speed or a smaller twist D ₂ . About the bearing elements 6 a kind of slippage is generated during launch, through which the comparatively large rotational speed of the projectile casing 2 not completely on the freight container 5 is transmitted. This results in a spin decoupling between the projectile shell 2 and the freight container 5 , which is why the intercepting element 7 when exiting the cargo hold 4 has a suitable rotational speed for reliable deployment under the influence of centrifugal force F.

As bearing elements 6 come different types of bearings in question, such as plain bearings, needle roller bearings, ball bearings, etc., where on the Pa parameters of the bearing elements 6 the desired rotational speed difference between the projectile shell 2 and the freight container 5 can be set.

Inside the freight container 5 is a piston 10 arranged displaceable back and forth. The movements of the piston 10 are over the inside surfaces of the freight container 5 guided. On the pointing in the direction of flight side is the piston 10 over a strain relief 11 protected against overload and a decoupling element 12 rotatably coupled to the front of the freight container 5 tethered. On the opposite side is a fastener 9 with the piston 10 connected, which concentric to the axis of the cargo projectile 1 extends. In the embodiment, a hollow cylindrical pipe section serves as a fastening element 9 , The interception element 7 is over several connections 17 to the piston 10 or the fastener 9 tethered. Also the connections 17 can with strain relief elements 18 Be provided to impermissibly large forces in the deployment of the interceptor 7 to intercept in its intercept position.

At the rear end of the cargo projectile 1 or at the rear of the freight container 5 is a dispensing element 8th arranged, which is the application of the interception element 7 facilitated in its intercept position. Also the connection of the Ausbringelements 8th is via a decoupling element 13 rotatably coupled and over a strain relief 19 protected against overload. The dispensing element is a kind of brake parachute which is in the freight container 5 folded is stored.

In addition, in the front area of the cargo projectile 1 between its top and the cargo hold 4 an opening 15 provided, through which an air flow L in the interior of the freight container 5 against the piston 10 is guided. This air flow is used to apply the interceptor 7 ,

Below are the individual processes during the transfer of the cargo projectile 1 from its transport position in the in 3 illustrated Abfangstellung explained.

After successful launch of the cargo projectile 1 in the direction of the trajectory F _{1 of} the enemy missile 50 the cargo missile moves 1 along the trajectory F ₂ , cf. also 1 , Shortly before the calculated intersection S of both trajectories F ₁ , F ₂ is the cargo projectile 1 transferred to the Abfangstellung, that is the interceptor 7 is unfolded and as a large-scale obstacle or as a large collision body in the trajectory F _{1 of} the opposing missile 50 positioned.

For this purpose, for example, controlled by a proximity sensor, the ground 3 of the cargo projectile 1 from the projectile shell 2 separated, which can be done for example via a blast. At the same time the opening 15 in the front area of the projectile shell 2 opened, which is also done by a blast. This will cause the air inlet duct 14 open, allowing a flow of air L into the interior of the freight container 5 entry. About the air flow L is the piston 10 contrary to the direction of flight of the cargo projectile 1 moved backwards, causing the dispensing element 8th the cargo space 4 of the cargo projectile 1 leaves.

In the dispensing element 8th it is a kind of brake parachute, which emerges when leaving the cargo hold 4 inflates and in this way a tensile force on the fastener 9 or the piston 10 exerts, so that the piston 10 and with this the interception element 7 towards the open end of the freight container 5 to be moved. Due to the spin decoupling element 13 become the rotational movements of the freight container 5 not on the standing in the wind at this time Ausbringhilfe 8th transfer.

Like the illustration in 5 shows, the piston moves 10 under the influence of the over the Ausbringelement 8th generated tensile force supported by the air flow L in a position in which the radially around the fastener 9 unfolded intercepting element around 7 from inside the cargo hold 4 exit. Because the freight container 5 in rotation, the interception element begins 7 with the leaving of the freight container under the influence of a radially outward centrifugal force F to unfold, as shown in 6 is shown. The unfolding is over in the peripheral areas of the intercepting element 7 arranged weights 16 supports a rapid development. After deployment, the decoupling element comes 12 to bear, which after the deployment of the intercepting element 7 further rotations of the intercepting element 7 opposite to the further rotating freight container prevents.

After deployment, the net-like interceptor forms 7 a large-scale interception surface, which faces the approaching enemy missile 50 in the way and intercept this.

Due to the over the bearing elements 6 realized decoupling of the freight container 5 opposite the projectile shell 2 can be used for the centrifugal force propagation of the intercepting element 7 required rotational speed D _{2 of} the intercepting element 7 regardless of the rotational speed D _{1 of} the projectile casing 2 be set to a value advantageous for its development.
