Abstract

PURPOSE:To reduce the impact pressure of jet, contributing for the penetration of a reaction armor, remarkably and penetrate a main armor surely by the jet by a method wherein a liner for producing jet in a warhead is constituted of a carbon series material such as graphite and the like or an aluminum material. CONSTITUTION:A liner 6 in an advance warhead 1 is constituted of carbon series material or graphite so that an impact pressure against the explosives 63 of reaction armors 62, which is generated by the jet Jp of the warhead, is reduced to a value lower than a predetermined value. When a launched guided projectile impacts the tank of enemy bursting charge 8 is initiated. The liner 6 is collapsed in accordance with the initiation and the jet JP, collimated and ejected forwardly, is produced whereby the reaction armors 62 are penetrated, however, the impact pressure of the produced jet Jp is lower remarkably compared with a jet produced from a liner made of copper since the liner is made of graphite. Since the impact pressure of the jet is low, the explosives 63 of the reaction armors 62 are not initiated by the jet Jp whereby plates 64 are penetrated without initiating any explosive 63 of the reaction armors 62.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention is a molding for anti-reactive armor for penetrating the main armor of a tank, etc. and the reactive armor attached to the surface of the main armor with a jet generated from a liner by detonation of an explosive charge. Concerning explosive warheads.

2. Description of the Related Art As a warhead for an anti-tank shell, an explosive charge is sealed in a liner and filled in the shell, and when the explosive charge is detonated, the liner collapses to generate a high-temperature, high-pressure jet heading forward. There is a so-called shaped explosive warhead that uses this jet to penetrate the armor of tanks and other vehicles.

[0003] The liner in this shaped explosive warhead is exposed to a pressure of more than 1,000,000 atmospheres and a temperature of more than approximately 3,000°C during jet generation, and at this time, fluid viscosity is required as an important factor. Conventionally, it has been made of a metal material such as copper or tungsten.

By the way, for the purpose of reducing the penetration power of such shaped explosive warheads, what is known as reactive armor is known. As shown in Figure 7, this reactive armor (62)
The original armor is the main armor (61), and the upper and lower plates (64),
(64) Explosives (63) are loaded between the main armor (6
1) is attached and fixed. And this is shown in Figure 8 (
As shown in a), the jet (J) from the shaped explosive warhead
When it ejects and perforates the plate (64), as shown in Fig. 8(b)
As shown in the figure, this jet (J) causes the plate (6
The explosive (63) between 4) and (64) reacts and detonates, blowing both plates (64) and (64) up and down, thereby preventing the subsequent penetration contact of the jet (J) with respect to the plate (64). It is designed to reduce its penetrating power. Therefore, it is unavoidable that the penetration power of the above-mentioned shaped explosive warhead will be significantly reduced against this reactive armor.

[0005] Therefore, in order to ensure the ability to penetrate this reactive armor, composite molded explosive warheads have been proposed. This warhead consists of a pioneer warhead and a main warhead, each of which has an explosive charge. As shown in Figure 9(a), first, the jet (Jp) of the pioneer warhead fires the explosive charge (63) of the reactive armor (62).
) to blow off the plates (64), (64), and then, as shown in Figure 9(b), by piercing the main armor (61) with the jet (Jm) of the main warhead with a delay in detonation. , is designed to neutralize reactive armor (62).

[0006]

However, even this composite molded explosive warhead is not perfect and has the following problems. That is, first, as shown in FIG. 10, the optimal value of the difference in detonation time between the pioneer warhead and the main warhead changes depending on the firing angle and position of the jet relative to the reactive armor, so it is difficult to set this optimal value.

Furthermore, the setting of the above-mentioned detonation time difference has a limit depending on the speed and structure of the warhead, and it is difficult to apply it to howitzers for tank guns, which normally have a speed of 1000 m/s or more.

[0008]Furthermore, for multiple reactive armors in which reactive armors are installed in multiple stages, no effect can be expected by simply setting the detonation time difference. In other words, as shown in FIG. 11(a), for example, if the target has two stages of reactive armor (
62), (62), the jet of the pioneer warhead detonates and removes the first stage (outer) reactive armor (62), but then, as shown in Figure 11(b), the main warhead The warhead jet (Jm) has second stage (inner) reactive armor (6
Main armor (61) because the penetration contact point is changed by 2)
will no longer be intrusive.

The purpose of this invention is to change the liner material in the shaped explosive warhead to reduce the impact pressure of the jet, prevent the explosives in the reactive armor from detonating, and ensure that the jet penetrates the main armor. It is in.

[Means for solving the problem] To achieve this purpose,
In this invention, the liner for jet generation in the warhead is made of carbon-based material such as graphite or aluminum material.

That is, in general, the conditions for detonating an explosive charge (explosive charge for reactive armor) include threshold values for each explosive charge with respect to applied energy, pressure, and temperature. It is considered that whether or not the reactive armor is detonated by the jet of the shaped explosive warhead is strongly influenced by impact energy Ec, impact pressure P, and impact force F, and these elements are given by the following equation. First, the impact energy Ec is the impact pulse (
pressure) time t, explosive density ρE, explosive sound speed C
As E, it is expressed as Ec = t・P2/ρE・CE...■. In addition, the impact pressure P is calculated as follows, where V is the jet velocity of the shaped explosive warhead, ρ is the density, and C is the speed of sound, P=V・{
(ρ・C)j ・(ρ・C)T }/{(ρ・C)j
+(ρ・C)T }


...■ (the subscript j indicates the jet, and T indicates the target), and the impact force F is the jet cross-sectional area S
It is expressed as F=P・S...■.

According to these equations, by lowering the impact pressure P, both the impact force F and the impact energy Ec can be reduced. In order to reduce the impact pressure P, it is sufficient to select a material with low acoustic impedance ρ・C for the liner, but as for the sound velocity C, collimating (
3000 m/s to produce a convergent jet
Since the above is necessary, it cannot be lowered, and it is necessary to lower the density ρ. The light metal beryllium (Be) can be used to reduce the density, but it is highly toxic and poses a problem in terms of environmental pollution. Therefore, in the present invention, a carbon-based or aluminum-based material is specified as the low-density material.

In the annular space, there is a booster charge (2) in contact with the above explosive (26).
8) is also attached to the rear surface of the spacer (27) and the detonator holder (25).
) A conductive explosive (29) in contact with the conductive explosive (28) is filled in the gap between the front surface and the front surface. Detonator holder (
A through hole (25a) is formed in the center of the detonator (25), and an electric detonator (30) whose front end is in contact with the detonator (29) is inserted into the through hole (25a).

Therefore, in this embodiment, FIG.
As shown in the figure, the fired guided artillery shells hit the main armor (61).
When approaching or landing within a predetermined distance of an enemy tank equipped with, for example, two stages of reactive armor (62), (62) on the surface of The explosive charge (9) detonates, and the explosive charge (8) is detonated by the detonation of the transfer charge (9). Along with this, the liner (6) collapses and the jet (Jp) is collimated and ejected forward.
) is generated, and this jet (Jp ) reacts with reactive armor (
62) and (62).

[0031] At this time, since the liner (6) of the pioneer warhead (1) is made of graphite as a carbon-based material, the impact pressure of the generated jet (Jp) is significantly greater than that of a liner made of copper. low. In this way, since the impact pressure of the jet (Jp) is low, the jet (Jp) causes each reactive armor (62) to

Furthermore, since the explosives (63) of each reactive armor (62) are not detonated in this way, the plates (64), (

Jet (Jp) of this pioneer warhead (1)
After that, the main warhead (21) is released after a predetermined time delay.

9), then the transfer charge (28) detonates, and this transfer charge (28) detonates.
The explosive charge (26) is detonated by the detonation of 8). Along with this, the liner (23) collapses and a jet (Jm) is generated in the same way as above, and this jet (Jm) blows off the pioneer warhead (1) and shell (19) and collimates it forward. gush.

[0034] At that time, the above-mentioned reactive armor (62), (62)
The explosive (63) is the jet (Jp) of the pioneer warhead (1)
Since the warhead is pushed away from the penetration point of the warhead to the periphery, even if the impact pressure of the jet (Jm) of the main warhead (21) is high, there is no explosive (63) to react to it. As a result, as shown in FIG. 2(b), the jet (Jm) of the main warhead (21) is not inhibited by the reactive armor (62), (62), and the jet (Jm) of the main warhead (21) is 6

(Example 2) FIG. 3 shows Example 2 (in addition,
The same parts as in Figure 1 are given the same reference numerals and detailed explanations are omitted), and the pioneer warhead (1) is replaced by the main warhead (21').
It is placed on the rear side.

[0036] In this embodiment, the pioneer warhead (1) is the same as in Example 1, and the main warhead (21') is partially different. That is, a bullet shell (19') is attached to the front end of the pioneer warhead (1).
) The shell (22) of the main warhead (21') is concentrically joined together. The bullet shell (19') is of Example 1.
The detonator holder (25) serves as a detonator holder (25), and a retaining ring (42) as a partition wall is formed at the center in the longitudinal direction. The void on the front side of this retaining ring (42) is filled with a conductive charge (29) via a cushion (33), and this conductive charge (29) is detonated with an electric detonator (30).

2a) is formed through it. The rear end of a cylindrical liner (35) communicates with the center hole (42a) of the retaining ring (42), and the front end of this liner (35) is connected to the rear end of the liner (23) that constitutes the front wall of the explosive chamber.

Therefore, in this embodiment, as shown in FIG. 2, when the explosive charge (8) of the pioneer warhead (1) is detonated,
The jet (Jp) generated along with this is the through hole (3

After this, the explosive charge (26) of the main warhead (21') detonates and the liners (23) and (35) collapse to generate a jet (Jm), which causes the reactive armor (62), It is possible to reliably penetrate the main armor (61) without being hindered by (62), and thus the same effect as in Example 1 can be obtained.

(Embodiment 3) FIG. 4 shows Embodiment 3 of the present invention, which is applied to a single shaped explosive warhead. In this embodiment, a liner (52) is placed inside a bottomed cylindrical bullet shell (51).

) is filled. A spacer (5
8) is arranged, and the outer periphery of this spacer (58) and the bullet shell (5
1) The space between the inner periphery and the inner periphery is filled with a booster explosive (54). The gap between the rear surface of the spacer (58) and the front surface of the bottom wall of the shell (51) is filled with a lead explosive (55), and this lead explosive (55) is a detonator that penetrates the center of the bottom wall of the shell (51).

In this embodiment, when the detonator (56) is energized, the conducting charge (55) and the booster charge (54) detonate and the explosive charge (53) is detonated, as shown in FIG.
53), the main liner (52a) collapses and a jet (Jm) is ejected, but the main liner (52a)
Since a graphite sub-liner (52b) is joined to the center of the jet (Jm), the graphite sub-liner (52b) penetrates the reactive armor (62), (62) before the jet (Jm) ejects. A jet (Jp) (see Fig. 2(a)) with reduced impact pressure that contributes to
2), (62) can be perforated without detonating. Therefore, even if the target has reactive armor (62), (62), the jet (Jp) will pierce the plate, and the pressure of penetrating the plate will cause the reactive armor (62), (62) to explode ( 63) from the penetrating contact to the periphery, and the subsequently generated main liner (52
The main armor (61) can be reliably penetrated by the jet (J) (see Figure 2(b)) produced by a).

(Example 4) FIG. 5 shows Example 4 (in addition,
(The same parts as in FIG. 4 are given the same reference numerals and detailed explanations thereof are omitted.) This is the single-head molded explosive warhead of Example 3 with an increased number of secondary liners. In this embodiment, the liner (52) includes a main liner (52a) made of copper that generates a jet (Jm) that penetrates the main armor (61), and a cone-shaped first and Second two sub liners (52b), (52c

The jet (Jm) is attached integrally so as to be generated on the same axis as the jet (Jm). Of the two secondary liners (52b) and (52c), the main liner (52
The second sub-liner (52c) on the rear side near a) is made of an aluminum-based material, and the first sub-liner (52b) adjacent to the front side of this second sub-liner (52c) is made of a second sub-liner ( 52c) are each composed of graphite having a different density.

Therefore, in this embodiment, the two sub liners (52b) and (52c) are integrally attached to the front side of the central part of the main liner (52a) made of copper, overlapping in the front and rear direction. When the explosive charge (53) is detonated, jets (Jp) and (Jp) are first generated by the first sub-liner (52b) on the front side, then the second sub-liner (52c) on the rear side, and finally A jet (Jm) of the main liner (52a) is generated. The second sub-liner (52c) on the rear side is made of an aluminum-based material, and the first sub-liner (52c) on the front side is made of an aluminum-based material.
2b) are each composed of graphite, so
Jet (Jp) by the first sub-liner (52b)
) is low, and the impact pressures of the jets (Jp) and (Jm) gradually increase from the second sub liner (52c) to the main liner (52a). For this reason, a plurality of (three or more) reactive armors (62), (62), ... are stacked in multiple stages on the surface of the main armor (61), and each of them has a different reaction sensitivity (explosive ignition sensitivity). Main armor (
Even if the jets (Jp) of the two sub liners (52b) and (52c) are different from each other so that the more sensitive the side (61)
), so the reactive armor (62), (6
2),... with the corresponding sub liners (52b), (5
2c) jet (Jp) can be used to penetrate without detonation. As a result, a multi-stage reactive armor (62
), (62), ... can all be neutralized, and the subsequent jet (Jm) of the main liner (52a) can reliably penetrate the main armor (61).

[0044] In this case, reactive armor (62), (62
),..., as mentioned above, is not in the order in which the main armor (61) side is more sensitive, and is expected to be different from that order, the reaction sensitivity of the first and second sub liners ( The materials of 52b) and (52c) may be changed.

Furthermore, the number of sub liners is not limited to two as in the above embodiment, but can be increased to three or more depending on the number of stages of the reactive armor (62).

(Example 5) FIG. 6 shows Example 5 (FIG. 4
The same parts are given the same reference numerals), and in the above single-head molded explosive warhead, the secondary liners (52b), (52c)
The mounting structure has been changed. That is, an opening (52a') is formed in the center of the main liner (52a) made of copper, that is, in the part that is involved in the jet initially generated by the detonation of the explosive charge (53). Further, the second sub-liner (52c) extends rearward to the main liner (52c).
It has a tapered cylindrical shape that converges at the same taper angle as a),
And the diameter of the larger diameter side is the opening of the main liner (52a) (
It has the same diameter as the opening (52a'), and its large diameter part has the same diameter as the opening (52a').
') in a substantially airtight manner. Further, the first sub liner (52b) is connected to the main liner (52a) toward the rear.
It has a cone shape that converges at the same taper angle, and its opening side diameter is the same as the small diameter part of the second sub liner (52c), and its opening side end is converged at the same taper angle as the second sub liner (52c).
) is engaged in a substantially airtight manner with the small diameter portion of the The two sub liners (52b) and (52c) each have a jet (
Jp ), (Jp ) are generated on the same axis as the jet (Jm ) of the main liner (52a) and
They are lined up in series from front to back and are integrally fitted to close the opening (52a') of 2a). The second sub-liner (52c) on the front side is made of an aluminum-based material, and the first sub-liner (52b) on the rear side adjacent to the second sub-liner (52c) is different from the second sub-liner (52c). Each is composed of graphite with different densities.

In this example, the main liner made of copper (
Since the two sub-liners (52b) and (52c) are integrally fitted into the center opening (52a') of 52a), unlike the above-mentioned Example 4, the detonation of the explosive charge (53) first causes , jets (Jp ) and (Jp ) are generated by the first subliner (52b) on the rear side, then the second subliner (52c) on the front side, and finally the main liner (52a) generates jets. (Jm) is generated. The first sub-liner (52b) on the rear side is made of graphite, and the second sub-liner (52c) on the front side is made of an aluminum-based material, so that the jet by the first sub-liner (52b) is (JP)
The impact pressure is low, and as it goes from the second sub liner (52c) to the main liner (52a)
) the impact pressure increases. For this reason, the above Example 4
Similarly, there are multiple reactive armors (61) on the surface of the main armor (61).
2), (62), ... are installed in multiple stages, and the reaction sensitivity (explosive ignition sensitivity) of each of them differs so that the side closer to the main armor (61) is more sensitive, By neutralizing all of these multi-stage reactive armors (62), (62), etc., the jet (Jm) of the main liner (52a) can reliably penetrate the main armor (61).

[0048] Also in this case, the reactive armor (62),
When it is expected that the reaction sensitivity of (62), ... will be different from the order in which the main armor (61) side becomes more sensitive, the materials of the first and second sub liners (52b), (52c) will be adjusted accordingly. Just replace it. In addition, the number of secondary liners may be increased or decreased to one or three or more depending on the number of stages of the reactive armor (62), in addition to two.

In each of the above embodiments, jet (Jp
) liner (6), (52b
) is made of graphite, but it can be changed to other carbon-based compounds including organic polymer compounds such as polycarbonate, nylon, and fluorine-based resins. Also,
Carbon may be mixed with other elements to achieve performance comparable to graphite. Furthermore, it may be constructed from an aluminum-based material instead of a carbon-based material. In short,
When generating a jet, a collimated jet with a high melting point and high sound velocity is obtained, and the jet (Jp)
Any material may be used as long as it can reduce the impact pressure of the reactive armor (62), (62) against the explosive (63) to a predetermined level or less.

Furthermore, in each of the above embodiments, the liner (6)
, (52b), and (52c) have a tapered shape with a constant inclination angle, but the present invention is not necessarily limited thereto. That is, the present invention also includes a liner having a shape in which the inclination angle changes midway in the front-rear direction depending on the jet to be generated, for example, a trumpet shape such as the liner (23) in FIG. 1. do. In that case, by making the taper angles of the main liner (52a) and the sub liners (52b), (52c) different from each other in Example 5, each liner (52a), (52b), (
52c) It is also possible to change the inclination angle at the engaging portions between the two.

Furthermore, it goes without saying that the present invention can be applied to warheads other than anti-tank guided artillery shells.

Incidentally, when the present inventor conducted tests on warheads having the configurations of the above embodiments, the following was confirmed.

1. Graphite liners provide well-collimated jets similar to metal liners.

2. The following types of warheads can pierce reactive armor without detonating it.

Explosive diameter (mm) 25 35 40
50 test quantity 2 6
2 23. A static explosion test of a composite molded explosive warhead with a graphite liner attached to a pioneer warhead with an explosive diameter of 35 mm against reactive armor showed that the jet of the main warhead passed through the hole drilled by the pioneer warhead, and the penetration length did not decrease. do not have.

[0056]

As explained above, in the invention according to claim 1 or 2, the liner of the pioneer warhead for penetrating the reactive armor in a composite molded explosive warhead is destroyed by the jet generated as the liner collapses. It is made of carbon-based or aluminum-based material so that the impact pressure against the explosive is reduced to a predetermined level or less. Further, in the invention of claim 3, 4, 5, 6 or 7, the liner of the part that generates the jet that contributes to the penetration of the reactive armor in the single-head molded explosive warhead is made of a similar carbon-based or aluminum-based material. . Therefore, according to these inventions, it is possible to significantly reduce the impact pressure of the jet that contributes to the penetration of the reactive armor, and to prevent the jet from detonating the reactive armor. Therefore, even if there are multiple layers of reactive armor on the surface of the main armor at the target, the jet pierces the plate, and the pressure during penetration of the plate pushes the explosives in the reactive armor away from the penetration point to the surrounding area, and the subsequent jets can reliably penetrate the main armor.

In particular, in the invention of claim 5, the front surface of the main liner that generates the jet that penetrates the main armor and the part that initially generates the jet upon detonation of the explosive charge is made of a carbon-based or aluminum-based material. In the seventh aspect of the invention, a jet is initially generated in the main liner by detonation of an explosive charge. Two or more sub-liners made of carbon-based or aluminum-based materials are fitted in series in front and back to close the opening of the part, and the adjacent sub-liners are made of different materials with different densities. It was composed of Therefore, according to these inventions, even in a multi-stage reactive armor in which a plurality of reactive armors having different reaction sensitivities (explosive ignition sensitivities) are stacked on the surface of the main armor, the materials of the plurality of secondary liners are By selecting each of the jets so that the reaction sensitivity is less than or equal to the reaction sensitivity of each reactive armor, each reactive armor can be penetrated without exploding by the jet of the corresponding secondary liner, neutralizing the multi-stage reactive armor, and then The main liner's jet can reliably penetrate the main armor.
