Description

The invention relates to a holding device for adjusting a projectile, in particular a missile, in a launching tube or launcher. Alternatively, such a holding device is also referred to as a latch mechanism. The holding device comprises a parallelogram with a parallel to a receiving device longitudinal component, wherein a pin is arranged on the longitudinal component. The pin is adjustable in a transverse recess of the projectile. In particular, the recess may be formed perpendicular to a firing direction of the projectile. In other words, the pin of the parallelogram is in a stop position prior to launch of the projectile and the projectile is held in place by the pin in the launch tube. The pin described here is further lowered during a departure or acceleration of the projectile by the parallelogram in the receiving device. This means that the pin comes out of the recess of the projectile.

The receiving device has a bottom surface, a top surface opposite the bottom surface and an end face, wherein the front side connects the bottom surface with the top of the receiving device.

In defense technology autonomously acting projectiles are used to combat targets with increasing tendency. These projectiles are used depending on the application specification against light to heavy armored vehicles application. The importance of such projectiles or missiles is steadily increasing. In particular, projectiles for the shoulder closure of great importance and are constantly evolving.

In order to prevent the projectile from falling out during transport of the projectile in a guided missile system, holding devices are known. The holding device holds the projectile in the launching tube or launcher both during transport and during a briefing phase of a shoot.

In current holding devices, in particular Latch mechanisms used in guided missile systems, the parallelogram is accelerated so much during the outgoing of the projectile that it strikes the receiving device so strongly that it is catapulted back towards the projectile. In this case, the pin located on the parallelogram exerts a negative pitching moment - a so-called pitch down moment - on the projectile. This is due in particular to the fact that when accelerating the projectile, the parallelogram is lowered into the receiving device so fast or accelerated that the parallelogram and thus the pin in the direction of its initial position or holding position thrown back, back, or zurückkatapultiert. In this case, the pin located on the parallelogram hits the projectile accelerated in the firing direction and causes the pitch down moment described here.

It is the object of the present invention to further develop a holding device, so that in particular by the holding device influencing a trajectory of the projectile is prevented.

This object is achieved by a holding device of the aforementioned type, wherein the receiving device comprises a safety gear, wherein the parallelogram after lowering can be fixed by the safety gear. Thus, the catching device can prevent the parallelogram and the pin from being thrown back, back or catapulted back.

In the holding device according to the invention, therefore, the solution of the task is essentially to further develop the receiving device and to provide with the safety gear. Furthermore, a guided missile system can be operated by the holding device according to the invention.

The invention provides a holding device according to claim 1 and a method for operating a guided missile system according to claim 10.

Preferred developments are the subject of the respective subclaims.

According to a preferred embodiment, the parallelogram comprises four joints, wherein by the four joints, a movable, parallel true displacement of the pin is feasible. That means that the pin by a Parallelogram from the recess of the projectile occurs or leaves. Thus, the holding device can be particularly space-saving integration in particular in the guided missile system.

According to a further preferred embodiment, the safety gear is designed as a snap device with a shaft on the end face of the receiving device. The front side of the receiving device can be arranged in particular in the firing direction of the projectile. The snap device holds the pin in its final position after lowering the parallelogram. Vorteilhalfter way, the snap device has a slight resistance, so that the snap device when lowering the parallelogram with little force is wegdrückbar. At the same time, however, it is necessary to adjust the resistance such that snap action of the snap device is correspondingly fast in order to prevent the parallelogram from being thrown back, back or catapulted back. For this purpose, for example, a torsion spring can be used which can be integrated via a pivot point of the snap device. At the snap device itself, a contact surface was formed, which is aligned in the unloaded state in a 90 ° position to the bottom surface of the receiving device and may be remote from the end face of the receiving device.

According to a further preferred embodiment, the safety gear is designed as a spring hook on the front side of the receiving device. The spring hook hooks at least partially on an upper edge of the longitudinal component of the parallelogram. In particular, the pin is arranged on the upper edge. By the spring hook the parallelogram can be fixed in its final position. This is the spring hook during lowering of the parallelogram in the direction of the front side, and as soon as the spring hook slips over the upper edge of the longitudinal component, it springs back into its original position. That is, the spring hook prevents the Zurückkatapultieren the parallelogram or the pin.

According to a further preferred development, the catching device is designed as a spring, which is arranged between an underside of the longitudinal component and the bottom surface of the receiving device. Thus, by retracting the spring after lowering the parallelogram, it is alternatively possible to prevent the pins from being catapulted back. For example, the spring is designed as a torsion spring.

In particular, at least one corner region of the longitudinal component facing away from the upper edge of the longitudinal component can be rounded off in the lowering direction of the parallelogram. This makes it easier to hook in particular when lowering the parallelogram.

According to a further preferred embodiment, an upper edge of the longitudinal component terminates flush with the upper side of the receiving device after the parallelogram has been lowered. As a result, the safety gear can be arranged particularly easily in the receiving device. In particular, in this way a plane can be predefined in which the spring hook or the snap device hooks or snaps onto the upper edge of the longitudinal component for fixing the parallelogram.

According to a further preferred embodiment, the spring or spring hooks are formed from a spring steel. By spring steel reliability of the safety gear can be increased. Spring steel is also stainless and heat resistant, making spring steel particularly suitable for use as a safety gear.

According to a further preferred development, the parallelogram can be controlled by an integrated communication device. For example, the integrated communication device is arranged on the longitudinal component of the parallelogram. In particular, the parallelogram can be decoupled from its holding position by the integrated communication device which, for example, communicates with the parallelogram via a common interface shortly before the projectile leaves. Thus, the projectile can be adjusted safely in the launch tube during transport as well as during a briefing phase of a shoot.

According to a further preferred development of the pin is formed on one of the transverse recess facing side spherical. Due to the spherical configuration of the pins, tilting of the pins during insertion into the recess can be avoided.

1a-1c show schematic representations of a conventional holding device in a holding position ( Fig. 1a ), in a position during a departure of a projectile ( Fig. 1b ) and an end position ( Fig. 1c ).

Exemplary shows the 1a a holding device 100 and a projectile 50 in a holding position. The projectile 50 may, for example, be a missile and is located in a launching tube 4. The holding device described here is particularly suitable for use in guided missile systems 200. The reference numeral 20 of the holding device 100 denotes a parallelogram, wherein a longitudinal component 22 of the parallelogram 20 extends parallel to a receiving device 30. The longitudinal component 22 may be connected, for example, by means of two connecting legs 23 with the receiving device 30.

As in Fig. 1a shown on the longitudinal component 22, a pin 21 is arranged. The pin 21 is in the holding position in a recess 10 of the projectile 50. Further, the parallelogram 20 comprises four joints G1, G2, G3, G4, wherein by the four joints G1, G2, G3, G4, a movable, parallel true displacement of the pin 21 is feasible.

In the holding position, the connecting legs 23 make a right angle to the longitudinal component 22, the projectile 50 being adjustable by the pin 21 in the launching tube 4. That is, by the pin 21, the projectile 50 is held in the launching tube 4.

The longitudinal component 22 of the parallelogram 20 further includes an integrated communication device 60 through which the parallelogram 20 is controllable. The Fig. 1b shows the holding device 100 during a departure of the projectile 50 in the firing direction A1. The connecting legs 23 incline here in the firing direction A1 or exit direction of the projectile 50. As a result, the parallelogram 20 is lowered into the receiving device 30 and the pin 21 leaves the recess 10 of the projectile 50th

The Fig. 1c shows the holding device 100 in the end position. This means that the parallelogram 20 is completely lowered into the receiving device 30 and the connecting legs 23 extend substantially parallel to the upper edge 25 of the longitudinal component 22. However, before the end position of the holding device 100 sets, the parallelogram 20 is accelerated so much by the exit of the projectile 50, which hits it so strongly at its end position that in particular the pin 21 is catapulted back in the direction of the projectile 50 (see arrow in the direction of Projectile Z1). As a result, the pin 21 again strikes the projectile 50 still located in the firing tube 4, whereby a pitch down moment is induced. In particular, the pitch-down moment can bring the projectile from a trajectory calculated in advance of the departure.

In order to avoid in particular the pitch-down moment, the holding device 100 according to the invention comprises the receiving device 30 with a safety gear 40, wherein the parallelogram 20 can be fixed after lowering by the safety gear 40 (see Fig. 2a-2b . 3 and 4 ). In other words, the safety gear 40 prevents the return of the pin 21 after lowering the parallelogram 20 in the receiving device 30 and reaching the end position.

The receiving device 30 has a bottom surface 32, a bottom surface 32 opposite the top 33 and an end face 31, wherein the end face 31 connects the bottom surface 32 with the top 33 of the receiving device 30.

2a . b show schematic representations of a holding device with a detailed representation of a safety gear in a holding position ( Fig. 2a ) and an end position ( Fig. 2b ) according to a first embodiment.

In Fig. 2a , Reference numeral 100 denotes a holding device in the holding position. The safety gear 40 is designed as a snap device 45 with a shaft 46 on the end face 31 of the receiving device 30. The end face 31 of the receiving device 30 is arranged in the firing direction A1 of the projectile 50. The connecting legs 23 in the holding position with the top 33 of the receiving device 30 form a right angle. As in Fig. 2a 1, a corner region 27 of the longitudinal component 22 facing away from an upper edge 25 of the longitudinal component 22 is rounded off in the lowering direction of the parallelogram 20. This makes it easier to hook in particular when lowering the parallelogram 20.

In Fig. 2.b Reference numeral 100 denotes a holding device in the end position. In the end position, the connecting legs 23 are substantially parallel to the upper side 33 of the receiving device 30. The snap device 45 holds the pin 21 in its final position after lowering the parallelogram 20. Advantage halter manner, the snap device 45 has a slight resistance, so that the snap device 45 is wegdrückbar when lowering the parallelogram 20 with as little force. At the same time, however, it is necessary to set the resistance such that snapping the Snap device 45 is correspondingly fast in order to prevent the slinging back, recoil or Zurückkatapultieren the parallelogram. For this purpose, in particular, a torsion spring 47, for example a coil spring or bar spring can be used, which can be integrated over a pivot point of the snap device 45. At the snap device itself, a contact surface 48 is formed, which is aligned in the unloaded state in the 90 ° position to the bottom surface 32 of the receiving device 30. The snap device 45 also has a projection 49, which projects at least partially over the contact surface 48 and is provided for hooking or snapping the snap device 45 on the upper edge 25 of the longitudinal component 22. In particular, the projection 49 with the contact surface 48 encloses a right angle.

Fig. 3 shows a schematic representation of a holding device with a detailed illustration of a safety gear according to a second embodiment.

In Fig. 3 Reference numeral 100 denotes a holding device in the end position. The safety gear 40 is attached as a spring hook 16 on the end face 31 of the receiving device 30. The spring hook 16 hooks at least partially on the upper edge 25 of the longitudinal component 22 of the parallelogram 20 a. On the upper edge 25 of the pin 21 is arranged. By the spring hook 16, the parallelogram 20 can be caught or fixed in its final position. In this case, the spring hook 16 is pressed during the lowering of the parallelogram 20 in the direction of the end face 31, and as soon as the spring hook 16 slips over the upper edge 25 of the longitudinal component 22, it springs back into its original position. That is, the spring hook 16 prevents the Zurückkatapultieren the parallelogram 20 and the pin 21st

As in the FIGS. 2b and 3 shown, the upper edge 25 of the longitudinal component 22 is flush after lowering the parallelogram 20 flush with the top 33 of the receiving device 30 from. As a result, the safety gear 40 can be arranged particularly easily in the receiving device 30. In particular, a plane E1 can thereby be predefined in which the spring hook 16 or the snap device 45 hooks or snaps onto the upper edge 25 of the longitudinal component 22 for fixing the parallelogram 20.

Figure 4 shows a schematic representation of a holding device with a detailed illustration of a safety gear according to a third embodiment.

In Fig. 4 Reference numeral 100 denotes a holding device in the end position. The safety gear 40 is in Fig. 4 as a spring 15, which is arranged between a bottom 26 of the longitudinal component 22 and the bottom surface 32 of the receiving device 30 is formed. Thus, by contracting the spring 15, for example a helical spring, after lowering the parallelogram 20, a return catapulting of the pin 21 can be prevented.

Although the present invention has been described above with reference to preferred embodiments, it is not limited thereto, but modifiable in a variety of ways. In particular, the invention can be varied or modified in many ways without deviating from the gist of the invention.

Because the concept of the receiving device 30 with the catcher 40 can be extended to a variety of other applications such as mechanical components and is therefore not limited to missile systems.

The invention described above accordingly relates to a holding device 100 for adjusting a projectile 50 in a launching tube 4 with a parallelogram 20 with a parallel to a receiving device 30 longitudinal component 22, wherein on the longitudinal component of a pin 21 is arranged, the pin 21 in a transverse Recess 10 of the projectile is adjustable, and the pin 21 during a departure of the projectile 50 by the parallelogram 20 is lowered into the receiving device 30 and the receiving device 30 has a safety gear 40, wherein the parallelogram 20 is fixed by the safety gear 40 after lowering. Furthermore, the invention relates to a method for operating a guided missile system 200 with a holding device 100.
