Abstract

The invention is directed to the provision of a safety device to prevent premature detonation of ammunition, particularly low spin projectiles of the type in which a primer pellet is positioned in a rotor which rotates from an unarmed to an armed position upon firing. The safety device is biased under the action of the spring to project into a groove in the rotor so as to be engageable with an end face of the groove. If the projectile is fired with normal acceleration, the resulting force will cause the safety device to become disengaged from the groove in the rotor against the action of the spring. If acceleration is below normal, the safety device will engage the rotor and lock it in an unarmed position. An inertial mass lock is also provided as an additional measure against accidental or premature arming of the projectile. A retard mechanism delays rotation of the rotor to an armed position for a selected time period sufficient for the projectile to advance a safe distance from a gun or launcher before becoming armed.

Description

The present invention relates to a device for securing and sharpening an electrically ignitable ammunition body, with a squib installed in a squib, the squib carrier being secured by the inertial action of masses and being delayed by a mechanical inhibitor into the focus position.

The problem of securing ammunition bodies in projectiles, grenades, missiles etc. is gaining particular importance with the development of new high-performance explosives and weapon systems with increased ballistic performance. Accordingly, the security requirements have been increased, for example, NATO's MIL-STD (Military Standard) 1316 B of February 15, 1977 requires that at least two (physically) independent safeguards must be installed in an ammunition. This requirement has so far been difficult to meet, especially with low-swirl projectiles, so that in practice a second safety device has mostly been dispensed with.

An initial fuse fuse (DE-OS 1 912 750) of an igniter with a rotor with radial bores and a disk with radial slots (springs, tongues with a wedge effect) is known. This combination of safeguards ensures that minor bumps during transport do not cause unwanted firing and that the detonator is only unlocked in the area of about 7 m to 15 m from the muzzle of the gun barrel.

This known initial fuse fuse does not meet today's safety requirements, in particular the fuse is armored at a safety distance that is too short from the gun.

It is therefore an object of the present invention to provide a device for securing and sharpening an electrically ignitable ammunition body, which brings about a higher degree of security and can also be used in particular with low-swirl ammunition bodies.

The aforementioned object is achieved according to the invention in that a bolt which is longitudinally and partially transversely movable in a bore is arranged at least approximately in the line of the direction of the main acceleration of the ammunition body, that the bolt is loaded by a spring at least on one end face in the direction of the main acceleration and engages in a groove located in a part of the circumference of the squib support with a projection flange provided on the second end face. This solution allows a reliable control of the acceleration behavior of the ammunition body and prevents unwanted focusing. Due to the longitudinally and partially transversely movable bolt mentioned in the patent claim, transverse accelerations can be absorbed without the latter becoming jammed and thus impairing its functionality.

Advantageous developments of the subject matter of the invention are characterized in the dependent claims.

The device according to claim 2 is characterized by its simplicity and economy.

The embodiment according to claim 3 prevents the bolt from blocking even in the case of transverse accelerations which act on the ammunition body.

The solution shown in claim 4 is used for additional centering and guidance of the bolt, which is particularly advantageous in the case of an unstable flight of the ammunition body.

The device according to claim 5 ensures a defined support of the bolt and is therefore of great mechanical stability.

A particularly advantageous and space-saving solution is shown in claim 6.

The embodiment according to claim 7 is used in particular to supplement previous slider-like squib carriers with a retardation lock.

A relatively long groove according to claim 8 allows a correspondingly long monitoring of the rotation of the rotor.

The solution according to claim 9 prevents a jerky breakaway at the beginning of the rotary movement of the rotor and brings about a high degree of operational safety even in the case of the necessary, premature locking.

A groove designed according to claim 10 prevents further rotation of the rotor, even with high mechanical shock loads. A spring drive has proven to be particularly simple and reliable for moving the squib support into the armed position, see claim 11.

The inhibitor described in claim 12 allows a simple, system-dependent setting of the desired front pipe security.

The double mass lock described in claim 13 serves primarily to secure the transport and ensures safe unlocking in the direction of its main acceleration fired ammunition; it can also be coordinated with regard to the minimum acceleration values required for secure unlocking.

A variant executed according to claim 14 is particularly easy to manufacture in terms of manufacturing technology.

The embodiment according to claim 15 is advantageous in the cases in which the retardation lock has to work with a slide over a wide acceleration range.

The further development according to claim 16 is expedient in the case of limited space.

An embodiment according to claim 17 improves the functional reliability even with large changes in the lateral acceleration.

A simple optimization of the retardation behavior of the device results from claim 18.

In all drawings, the same parts are provided with the same reference numerals.

Fig. 1 shows a double, mechanically secured device in an electrically ignitable ammunition body M, which often occurs in its kind in projectiles, missiles, etc., ie in ammunition to be fired at high accelerations.

1, 1 denotes a conical bore 1 in a housing 7. A threaded ring 1a closes the bore 1 and at the same time centers a spring 8 which acts on a likewise conical bolt 2 with an end flange 3. The bore 1 has a cylindrical part 4 in addition to its conical part.

In the center of the housing 7 there is a squib 6, which is designed as a rotor with a pivot point D. The squib support 6 has a groove 5 on part of its circumference, which has an outgoing part 5a on one end side and an end face 5b on its other end side.

In the interior of the squib support 6 there is a squib 9 known per se, from which an insulated pin 10 protrudes. The outer sleeve of the squib 9 is connected to the ground via the bore 11 of the metallic squib support 6; The pole pin 10 protrudes into the tapered bore 12 of the squib support 6 in an electrically insulated manner.

On one end of the ammunition body M, in the direction of the main acceleration b _N , there is an electrical energy generator 13 known per se, consisting of an ignition generator with a safety and storage scarf device and target sensor.

The energy generator 13 has a telescopic contact 14, which rests with its contact surface 15 on the squib support 6.

On the opposite side there is an amplifier charge 16 (booster) which, with its initiation point 17, also projects into the housing 7 in the direction of the pivot point D of the squib support 6.

The right-angled coordinate system shown in FIG. 1 a shows the direction of the main acceleration b _{N of} the ammunition body M in the positive part of the abscissa. The ammunition body M is in this acceleration range when it is fired. After leaving the tube or its runway, the ammunition body M experiences a flow resistance, so that after a certain flight duration the positive acceleration values, which were continuously increasing before, become relatively negative values, ie for retardation. This area is designated by -b _N. During a real launch, an ammunition body experiences different angular positions on its ballistic trajectory, which result in components of its lateral accelerations b _Q (positive and negative).

If an ammunition body M flies on a conventional ballistic trajectory, the squib 6, initially locked by a double mass lock, is unlocked in a first step and learns from its starting position, FIG. 1, about the pivot point D a clockwise rotation. The acceleration forces, which unlock the double mass lock, also act on the conical bolt 2, whereby this is pressed due to its inert mass in the direction of the threaded ring 1a and thus is pulled out with its projection flange 3 from the groove 5 in the manner shown in Fig. 2. This enables the squib Carrier 6 in the predetermined time a rotation of 270 °, whereby the armored state shown in Fig. 2 occurs.

Here, the telescopic contact 14 of the energy generator 13 is spring-loaded into the bore 12 of the squib support 6 and contacts the pole pin 10, as a result of which the circuit is closed when the target sensor (impact contact, etc.) is closed and the ignition charge provided with an electrically conductive glow plug is ignited. The shock wave generated in the squib 9 causes a detonation transmission at the initiation point 17 of the booster charge 16.

If the flight of the ammunition M canceled for any reason prematurely, this rebounds for example, premature ti ^g an obstacle, so the 2'einwirkenden on the bolt acceleration forces change, so this again by the spring 8 causes in its final position in the Hole 1 is pressed; Now the projection flange 3 engages again in the peripheral, annular groove 5 and in turn acts tangentially on the squib support 6.

Before the predetermined pre-pipe time expires, the squib support 6 is now stopped in its rotation on the end face 5b by the projection flange 3. - Armoring without renewed acceleration of the ammunition body M is no longer possible. The state shown in FIG. 3 arises.

Further details of the subject matter of the invention can be described with reference to the device successfully tested in practice according to FIGS. 4-12. For reasons of clarity, the energy generator 13 and the booster charge 16 are only symbolized in FIGS. 4 and 5 by arrows.

4 shows a balance 18, which is surrounded by four balls 19, in a vertical sectional view. The balls 19 are concentric to the cylindrical balance 18 by a ball ring 20 and a clamping ring 21 guided. A mounting pin 22 serves as a hold-down device for this arrangement which represents an inhibitor.

In the same FIG. 4, the squib carrier 6 with its squib 9 is again visible, which is fixed in the bore 11 by means of a threaded pin 23.

In the squib support 6, a so-called closing piston 24 of a double mass lock can also be seen, which is guided into a large bore 27 which opens into the housing 7. A conical rotation 25 facilitates the partial sliding of the closing piston 24 from the squib support 6 into the housing 7. Another small bore 28 serves to exchange air in the bore 27 of the squib support 6 and limits its sliding path on one side.

Furthermore, the closing piston 24 has indentations into which the balls 42 of the double mass lock shown in FIGS. 9 and 10 engage. The central end of a reinforcement spring 29 engages in a peg-like part 32 (see FIG. 6) of the squib support 6 which has a slot 33 and which can cause the previously described rotation of the squib support 6.

5 - a view of the object of FIG. 4 from above - the design of the escapement with the balance 18 can be seen again. In addition, a stop pin 30 can be seen here, which acts on its cam-like stop 31 to limit the rotational path of the squib support 6.

The squib support 6 (rotor) shown in FIG. 6 is guided and centered in the housing 7, FIG. 4 through its cylindrical portions 36 and has the cam-like stop 31 on one end face and a pin 32 on its lower end face. The pin 32 is provided with a slot 33 into which the central end shown in Fig. 8 29a of the reinforcement spring 29 engages.

Also visible is the one-sided, slot-like recessed bore 11 for receiving the squib 9, as well as a thread 34 leading into this bore 11 and arranged perpendicular thereto, into which the threaded pin 23 serving to fix the squib can be screwed.

Four receiving bores 35 arranged at angles of 90 ° form the storage and retention for the four balls 19 known from FIGS. 4 and 5.

Above the pin 32 there are three further bores 27 and 27 'which are parallel to one another and which each merge into smaller bores 28 and 28' over a step. Transversely to this drilling is situated at the front of the Kugellauf- _'bore 37. - The distribution of all holes at this level 7 can be seen from the sectional view Fig where the overlying annular groove 5 with its end face 5b. See. Fig. 6, and its outgoing part 5a drawn in dashed lines, can be seen.

The reinforcement spring 29 shown in FIG. 8 and already mentioned is a clockwork spring which, in the housing 7, cf. Fig. 4, is hooked with its outer end 29b in the wound state.

The illustration in FIG. 9 shows the locking pins 38, 39 consisting of the masses 1 and 2, together with the central closing piston 24 in the locked state. The conical projection 25 and the tips 38 ', 39' of the locking pins 38 and 39 engage in the bores 27 and 27 "in the housing 7.

The locking pins 38 and 39 provided with identical masses are 38 ", 39" at their ends by likewise identical springs 40 and 41 with the same spring constants in the ge drawn position pressed. There is mechanical contact between the recess 26 in the closing piston 24 and the locking pins 38 and 39 by means of two balls 42 inserted in the ball barrel bore 37.

• Im Ruhezustand, d.h. bei der Lagerung und dem Transport der Munition, ist der in Fig. 9 gezeigte verriegelte Zustand ; vorhanden. Der Rotor - Zündpillenträger 6 - kann nicht in die Scharfstellung gedreht werden. Wird der Munitionskörper mit hoher Beschleunigung abgeschossen, so wirkt diese umgehend auf die beiden Massen der Sperrstifte 38 und 39 und entriegelt diese in der in Fig. 10 dargestellten Weise. Die Entriegelung ist aufgrund der beiden in der Kugellauf-Bohrung 37 vorhandenen Kugeln 42 einmalig; die Kugeln blockieren die Bewegung an den Stirnflächen des Schliesskolbens 24 und den Sperrstiften 38 und 39 (Teile 25, 38' und 39') und verhindern somit ein Rückfedern in die Position der Verriegelung.

This double mass barrier works as follows:

• In the idle state, ie during the storage and transportation of the ammunition, the locked state shown in FIG. 9 is; available. The rotor - squib support 6 - cannot be turned to the arming position. If the ammunition body is fired with high acceleration, it acts immediately on the two masses of the locking pins 38 and 39 and unlocks them in the manner shown in FIG. 10. The unlocking is unique due to the two balls 42 present in the ball barrel bore 37; the balls block the movement on the end faces of the closing piston 24 and the locking pins 38 and 39 (parts 25, 38 'and 39') and thus prevent springing back into the position of the locking.

The rotatable squib support 6 in the unlocked state, FIG. 10, experiences a torque in the clockwise direction through the spring 29. The resulting rotary movement is braked by the escapement with its balance 18, FIGS. 4 and 5, in that the balls 19 are pressed alternately into opposite recesses in the spherical ring 20 by the balance 18, which carries out an oscillating movement. A predetermined delayed rotary movement of the squib support 6 can thus be realized, in accordance with the required precoil security.

The delay times required in practice range from a few milliseconds to several seconds, depending on the type of ammunition and the design of the escapement.

The retar now controls physically irrespective of the rotary movement of the squib support 6 that has been initiated dation lock according to FIGS. 1 to 3, the rotary movement in relation to an acceleration behavior of the ammunition body contrary to the system.

The conical configuration of the bore 1, cf. Fig. 1, and the rotationally symmetrical conical bolt 2 prevent unwanted sticking of the bolt due to the selected cone angle in the range of 10 ° to 30 °, preferably 15 °.

The fact that this type of retardation lock is largely insensitive to transverse accelerations of the ammunition has proven to be a particular advantage.

Through the choice of material and the size of the bolt 2 and the spring 8, the retardation effect can also be predetermined within wide limits.

11 shows the rotationally symmetrical bolt 2 with its spring 8 in the coordinate system; the angle formed between the direction of the main acceleration b _N and the actual direction of acceleration is denoted by alpha.

The diagram in FIG. 12 shows the resulting values as multiples n of the normal acceleration g (= 9.81 m / sec ² ) as a function of the angle alpha for the materials aluminum, Al (p = 2.7 g / cm ³ ), steel, St (p = 7.8 g / cm ³ ) and Reconit (commercially available alloy of 92.5% W, 7.5% Ni / Cr / Cu; Güggi AG, Grenchen, Switzerland), Re (p = 18 g / cm ³ ).

This diagram shows that a floor can be safely reinforced and checked even under extreme acceleration conditions if the necessary absolute values are reached.

As the above explanations show, the subject matter of the invention can be integrated almost universally into existing electrical ignition systems. The practical dimensions of a cylindrical housing 7 are of the order of 20 mm in diameter and of the same length.

Nevertheless, if desired, slide-shaped squib carriers according to the invention can also be equipped in an analogous manner with a retardation lock, as shown in FIGS. 13 and 14 in a simplified form.

In an ammunition body M belonging to FIG. 13, the axis of symmetry S is identical to the direction of the main acceleration b _N. A slider-like squib support 6 'is arranged at an angle of 90 ° to the axis of symmetry S. In this - drawn in a secured position - there is a primer 9 with a pole pin 10, a keyway-like groove 5 'and a blind hole 43. In this hole, a reinforcement spring 29' (tension spring) is suspended at the end, which is also attached to a housing 7 'is attached.

The bolt 2 with its projection flange 3, which is identical to FIG. 1, lies in the groove 5 'and is also supported by a spring 8 on a threaded ring 1a.

In the axis of symmetry S, on the front side in the ammunition body M, is the energy generator 13 with its telescope contact 14 'resting on the squib support 6'. On the side opposite the power generator, the booster charge 16 'is at a small distance from the squib holder 6'. The inhibitor mechanism H acting on the long side of the squib carrier is symbolized by an arrow.

The operation of this device is analogous to that described above: The Be acting on the bolt 2 Be Acceleration forces move the projection flange 3 out of the groove 5 '. As a result, the reinforcement spring 29 'pulls the slide in the direction of the focus, where the pole pin 10 of the squib 9 is electrically connected via the contact surface 15. The squib 9 also ignites the booster charge 16 'in a manner already known.

If the acceleration forces acting on the bolt 2 experience an interruption, the projection flange 3 can likewise prevent the detonator from being focused in good time in a known manner on the end face 5b '.

The device according to FIG. 14 is constructed analogously to that according to claim 13, only to reduce the space requirement here the bolt 2 is arranged at an angle alpha to the axis of symmetry S of the ammunition body M and thus to the direction of the main acceleration b _N.

In order nevertheless to be able to guarantee reliable and axially accurate ignition of the booster charge 16 ', which is not shown here, the squib 9 is inclined, i.e. axially parallel to the axis of symmetry S, installed in the squib support 6 ".

The projection flange 3 'of the bolt 2 is designed like a pawl; The end face 5b "is also at the same angle in the groove 5" of the squib support 6 ". This ensures, if necessary, that the squib support 6" is securely and positively locked.

The optimal choice of the angle alpha, i.e. the installation position of the retardation lock can be optimized in a simple manner with the aid of the diagram in FIG. 12 and the dynamic flight behavior of the ammunition body M.

The device according to the invention ensures a high level of security even in cases where the ammunition holding (projectiles and missiles with boosters etc.) has relatively high lateral accelerations. It is also characterized by its simplicity, small size and the possibility of integrating it into existing or newly designed ignition systems.
