特開2013−231589号公報Japanese Unexamined Patent Publication No. 2013-231589

ところで、弾頭の起爆直前等、弾頭の製造後に、弾殻の破断後の破片形状を、弾頭の標的(ターゲット)等に応じて選択したいという要望がある。しかし、特許文献1では、弾殻の破断後の破片形状が弾殻の溝の配置に応じて決まるので、弾頭の製造後に破片形状を選択できない。 By the way, there is a demand to select the shape of the fragment after the warhead is broken, such as immediately before the detonation of the warhead, after the warhead is manufactured, according to the target of the warhead. However, in Patent Document 1, since the shape of the fragments after breaking of the shell is determined according to the arrangement of the grooves of the shell, the shape of the fragments cannot be selected after the warhead is manufactured.

本開示の目的は、弾頭の製造後に、弾殻の破断後の破片形状を選択できるようにすることにある。 An object of the present disclosure is to make it possible to select the debris shape after breaking of the shell after the warhead is manufactured.

第1の態様は、弾殻(11)と、上記弾殻(11)の内部に充填される主炸薬(16)と、上記主炸薬(16)を起爆させる第1起爆手段(17)とを備えた弾頭であって、表面にV溝(13a)が形成された金属製の長尺状の収容体(13)と、上記収容体(13)に収容された爆薬線用炸薬(14)とを有し、上記V溝(13a)を上記弾殻(11)の内面に向けた状態で上記弾殻(11)の内側に配設された成形爆薬線(12)と、上記成形爆薬線(12)の爆薬線用炸薬(14)を、上記第1起爆手段(17)による上記主炸薬(16)の起爆前に起爆させることが可能な第2起爆手段(18)とを備えていることを特徴とする。 In the first aspect, the shell (11), the main explosive charge (16) filled inside the shell (11), and the first detonation means (17) for detonating the main explosive charge (16) are used. A long metal housing (13) having a V-groove (13a) formed on its surface, and an explosive wire explosive (14) housed in the housing (13). A shaped charge wire (12) arranged inside the shell (11) with the V-groove (13a) facing the inner surface of the shell (11), and a shaped charge wire (12). The explosive line explosive (14) of 12) is provided with a second detonation means (18) capable of detonating the main explosive (16) by the first detonation means (17) before detonation. It is characterized by.

第1の態様では、第1起爆手段(17)による主炸薬(16)の起爆前に、第2起爆手段(18)に爆薬線用炸薬(14)を起爆させると、成形爆薬線(12)のV溝(13a)が外側に飛び出して弾殻(11)の内面にノッチ(N)を形成する。したがって、その後、第1起爆手段(17)に主炸薬(16)を起爆させると、弾殻(11)のノッチ(N)周りに応力が集中するので、弾殻(11)がノッチ(N)を境界として破断しやすい。 In the first aspect, when the explosive wire explosive (14) is detonated by the second detonation means (18) before the main explosive (16) is detonated by the first detonation means (17), the shaped charge wire (12) is detonated. V-groove (13a) protrudes outward to form a notch (N) on the inner surface of the shell (11). Therefore, when the main explosive charge (16) is subsequently detonated by the first detonation means (17), stress is concentrated around the notch (N) of the shell (11), so that the shell (11) becomes the notch (N). Is easy to break with.

一方、第2起爆手段(18)に爆薬線用炸薬(14)を起爆させていない状態で、第1起爆手段(17)に主炸薬(16)を起爆させる場合には、弾殻(11)に上述のようなノッチ(N)が形成されていない状態で主炸薬(16)が起爆するので、爆薬線用炸薬(14)の起爆後に主炸薬(16)を起爆させる場合とは異なる形状の破片に弾殻(11)を破断できる。 On the other hand, when the first detonation means (17) is detonated with the main explosive (16) while the second detonation means (18) is not detonated with the explosive line explosive (14), the shell (11) is used. Since the main explosive (16) is detonated in the state where the notch (N) as described above is not formed, the shape is different from the case where the main explosive (16) is detonated after the detonation of the explosive line explosive (14). The shell (11) can be broken into fragments.

このように、第1起爆手段(17)による主炸薬(16)の起爆の前に、第2起爆手段(18)による爆薬線用炸薬(14)の起爆を行った場合と行っていない場合とで、弾殻(11)の破断後の破片形状が異なるので、第1起爆手段(17)による主炸薬(16)の起爆の前に、第2起爆手段(18)による爆薬線用炸薬(14)の起爆を行わせるか否かによって、弾殻(11)の破断後の破片形状を選択できる。 In this way, before the detonation of the main explosive (16) by the first detonation means (17), the detonation of the explosive line explosive (14) by the second detonation means (18) may or may not be performed. Since the shape of the fragments after the shell (11) is broken is different, the explosive line explosive (14) by the second detonation means (18) is before the detonation of the main explosive (16) by the first detonation means (17). ) Can be detonated, or the shape of the fragment after the shell (11) is broken can be selected.

第2の態様は、第1の態様において、 上記弾殻(11)は、円筒形の本体部(11a)を有し、上記成形爆薬線(12)は、螺旋状に巻回された状態で上記本体部(11a)の外周端部に配設されていることを特徴とする。 In the second aspect, in the first aspect, the shell (11) has a cylindrical main body (11a), and the shaped charge wire (12) is spirally wound. It is characterized in that it is arranged at the outer peripheral end portion of the main body portion (11a).

第2の態様では、弾殻(11)の本体部(11a)の内側で成形爆薬線(12)が本体部(11a)の周方向に延びるので、第2起爆手段(18)による爆薬線用炸薬(14)の起爆後の状態で第1起爆手段(17)に主炸薬(16)を起爆させることにより、弾殻(11)の本体部(11a)を軸方向に意図した箇所で破断できる。 In the second aspect, since the shaped charge wire (12) extends in the circumferential direction of the main body (11a) inside the main body (11a) of the shell (11), it is used for the explosive wire by the second detonation means (18). By detonating the main explosive (16) with the first detonation means (17) in the state after the explosive (14) is detonated, the main body (11a) of the shell (11) can be broken at the intended position in the axial direction. ..

第3の態様は、第1又は2の態様において、上記成形爆薬線(12)は、複数設けられ、上記第2起爆手段(18)は、上記成形爆薬線(12)毎に設けられていることを特徴とする。 In the third aspect, in the first or second aspect, a plurality of the shaped charge wires (12) are provided, and the second detonation means (18) is provided for each of the shaped charge wires (12). It is characterized by that.

第3の態様では、複数の第2起爆手段(18)のうち、全部の第2起爆手段(18)に起爆を行わせるか、一部の第2起爆手段(18)に起爆を行わせるかによって、弾殻(11)の破断後の破片の形状及び大きさを選択できる。 In the third aspect, of the plurality of second detonation means (18), whether all the second detonation means (18) are to be detonated or some of the second detonation means (18) are to be detonated. Allows you to select the shape and size of the debris after breaking of the shell (11).

第4の態様は、第1〜3のいずれか1つの態様において、上記主炸薬(16)と上記成形爆薬線(12)との間には、緩衝材(15)が介在していることを特徴とする。 A fourth aspect is that, in any one of the first to third aspects, a cushioning material (15) is interposed between the main explosive charge (16) and the shaped charge wire (12). It is a feature.

第4の態様では、主炸薬(16)と成形爆薬線(12)との間には、緩衝材(15)が介在しているので、成形爆薬線(12)の爆薬線用炸薬(14)の爆発によって主炸薬(16)の爆発が誘発されない。 In the fourth aspect, since the cushioning material (15) is interposed between the main explosive (16) and the shaped charge wire (12), the explosive wire explosive (14) of the shaped charge wire (12) Explosion does not trigger the explosion of the main charge (16).

The missile (1) is equipped with a sensor (2) to identify the target. The sensor (2) is composed of, for example, an image sensor, an acoustic sensor, a vibration sensor, or the like, and outputs a signal necessary for detecting a target and identifying its type. Hereinafter, the rear of the missile (1) is referred to as "rear", and the front (direction of travel) of the missile (1) is referred to as "forward".

弾頭(10)は、略円筒形の弾殻(11)を備えている。弾殻(11)は、後方に解放する有底円筒形の本体部(11a)と、当該本体部(11a)の解放側を塞ぐように本体部(11a)に後方から取り付けられ、前方に解放する略有底円筒形の取付部(11b)とを有している。本体部(11a)の解放側端部の外周面には、雄ねじ部(図示せず)が設けられ、取付部(11b)の解放側端部の内周面には、雌ねじ部(図示せず)が設けられている。本体部(11a)の雄ねじ部を、取付部(11b)の雌ねじ部に螺合締結することで、本体部(11a)及び取付部(11b)が一体に組み付けられている。なお、本体部(11a)と取付部(11b)の組み付け方法はこれに限定されない。 The warhead (10) has a substantially cylindrical shell (11). The bullet shell (11) is attached to the bottomed cylindrical main body (11a) that is released rearward and the main body (11a) so as to block the release side of the main body (11a), and is released forward. It has a substantially bottomed cylindrical mounting part (11b). A male screw portion (not shown) is provided on the outer peripheral surface of the release side end portion of the main body portion (11a), and a female screw portion (not shown) is provided on the inner peripheral surface of the release side end portion of the mounting portion (11b). ) Is provided. The main body portion (11a) and the mounting portion (11b) are integrally assembled by screwing and fastening the male screw portion of the main body portion (11a) to the female screw portion of the mounting portion (11b). The method of assembling the main body portion (11a) and the mounting portion (11b) is not limited to this.

弾殻(11)の本体部(11a)の内側の外周端部には、図3及び図4にも示すように、長尺状の成形爆薬線(12)が螺旋状に複数回巻回された状態で配設されている。成形爆薬線(12)は、表面にV溝(13a)が形成された金属製の長尺状の収容体(13)と、上記収容体(13)に収容された爆薬線用炸薬(14)とを有している。収容体(13)を構成する金属としては、アルミ又は銅等の純金属が採用される。また、成形爆薬線(12)の径方向の幅Wは、弾殻(11)の本体部(11a)の周壁の厚さT1よりも短く設定され、例えば厚さT1の約1/2に設定される。収容体(13)は、そのV溝(13a)を本体部(11a)の内面に全周に亘って向けている。収容体(13)の外周面、すなわちV溝(13a)形成面と、弾殻(11)の内面とは、互いに当接しているか、又は間に微小な間隔を有している。成形爆薬線(12)は、LSC(Linear Shaped Charge)である。 As shown in FIGS. 3 and 4, a long shaped charge wire (12) is spirally wound a plurality of times around the inner outer peripheral end of the main body (11a) of the bullet shell (11). It is arranged in a state of being. The shaped charge wire (12) consists of a long metal housing (13) having a V-groove (13a) formed on its surface and an explosive wire explosive (14) housed in the housing (13). And have. As the metal constituting the housing (13), a pure metal such as aluminum or copper is adopted. Further, the radial width W of the shaped charge wire (12) is set shorter than the thickness T1 of the peripheral wall of the main body portion (11a) of the bullet shell (11), and is set to, for example, about 1/2 of the thickness T1. Will be done. The housing body (13) has its V-groove (13a) directed toward the inner surface of the main body portion (11a) over the entire circumference. The outer peripheral surface of the containment body (13), that is, the V-groove (13a) forming surface and the inner surface of the bullet shell (11) are in contact with each other or have a minute gap between them. The shaped charge line (12) is an LSC (Linear Sharped Charge).

成形爆薬線(12)の内側には、両端部が解放し、かつ本体部(11a)の内周面と平行な円筒形のシート状の緩衝材(15)が、本体部(11a)の軸方向全体に亘って配設されている。緩衝材(15)は、樹脂又はゴムで構成されている。緩衝材(15)の内部全体には、主炸薬(16)が充填されている。緩衝材(15)の厚さT2は、成形爆薬線(12)の径方向の幅Wよりも短く設定される。 Inside the shaped charge wire (12), a cylindrical sheet-shaped cushioning material (15) whose both ends are open and parallel to the inner peripheral surface of the main body (11a) is the shaft of the main body (11a). It is arranged in the entire direction. The cushioning material (15) is made of resin or rubber. The entire inside of the cushioning material (15) is filled with the main explosive charge (16). The thickness T2 of the cushioning material (15) is set shorter than the radial width W of the shaped charge wire (12).

取付部(11b)の内部には、主炸薬(16)を起爆させる第1起爆手段としての第1起爆装置(17)と、爆薬線用炸薬(14)を起爆させる第2起爆手段としての第2起爆装置(18)とが収容されている。第1起爆装置(17)及び第2起爆装置(18)は、それぞれ、起爆薬等を内蔵した電気雷管等で構成される。第2起爆装置(18)は、爆薬線用炸薬(14)を、第1起爆装置(17)による主炸薬(16)の起爆前に起爆させることが可能である。第1起爆装置(17)及び第2起爆装置(18)の配置は、図1に例示した配置に限られない。 Inside the mounting part (11b), there is a first detonator (17) as the first detonator to detonate the main explosive (16) and a second detonator as the second detonator to detonate the explosive wire explosive (14). 2 Detonator (18) is housed. The first detonator (17) and the second detonator (18) are each composed of an electric detonator or the like containing a detonator or the like. The second detonator (18) can detonate the explosive line explosive (14) before the main detonator (16) is detonated by the first detonator (17). The arrangement of the first detonator (17) and the second detonator (18) is not limited to the arrangement illustrated in FIG.

第1起爆装置(17)及び第2起爆装置(18)は、図2に示す起爆コントローラ(3)に接続されている。起爆コントローラ(3)は、ミサイル(1)に内蔵され、上記センサ(2)の出力信号を受け付けるようになっている。 The first detonator (17) and the second detonator (18) are connected to the detonator controller (3) shown in FIG. The detonation controller (3) is built into the missile (1) and receives the output signal of the sensor (2).

起爆コントローラ(3)の処理動作を図5により具体的に説明すると、最初のステップS101では、起爆コントローラ(3)は、センサ(2)の出力信号に基づいて、標的の脆弱性を推定する。脆弱性は、例えば、標的の色彩、サイズ等に基づいて推定される。S102において、起爆コントローラ(3)は、S101で推定した脆弱性に基づいて、弾殻(11)の破片サイズの調整が必要か否かを判定する。標的が所定の基準よりも脆弱である場合には、弾殻(11)の破片サイズの調整が必要であると判定し、標的が所定の基準よりも脆弱でない場合には、弾殻(11)の破片サイズの調整が必要ないと判定する。弾殻(11)の破片サイズの調整が必要でない場合には、S103に進む一方、弾殻(11)の破片サイズの調整が必要である場合には、S104に進む。 To specifically explain the processing operation of the detonation controller (3) with reference to FIG. 5, in the first step S101, the detonation controller (3) estimates the vulnerability of the target based on the output signal of the sensor (2). Vulnerability is estimated based on, for example, the color, size, etc. of the target. In S102, the detonation controller (3) determines whether or not it is necessary to adjust the fragment size of the bullet shell (11) based on the vulnerability estimated in S101. If the target is more vulnerable than the prescribed criteria, it is determined that the shell (11) debris size needs to be adjusted, and if the target is not more vulnerable than the prescribed criteria, the shell (11) It is judged that the adjustment of the fragment size is not necessary. If it is not necessary to adjust the fragment size of the bullet shell (11), the process proceeds to S103, while if the fragment size of the bullet shell (11) needs to be adjusted, the process proceeds to S104.

S103では、起爆コントローラ(3)は、第1起爆装置(17)に主炸薬(16)を起爆させる。これにより、弾殻(11)を、破片サイズを調整しない状態で主炸薬(16)の爆轟の衝撃圧によってランダムなサイズの破片に破断できる。 In S103, the detonator controller (3) causes the first detonator (17) to detonate the main explosive charge (16). As a result, the shell (11) can be broken into pieces of random size by the detonation pressure of the main explosive charge (16) without adjusting the piece size.

S104では、起爆コントローラ(3)は、第2起爆装置(18)に爆薬線用炸薬(14)を起爆させる。これにより、成形爆薬線(12)のV溝(13a)がメタルジェット化して外周側に(図3において矢印Xで示す方向)飛び出して弾殻(11)の内面に周方向に螺旋状に延びるノッチ(N)を外側に凹むように形成する。図3中、ノッチ(N)を二点鎖線で示す。このとき、主炸薬(16)と上記成形爆薬線(12)との間に、緩衝材(15)が介在しているので、成形爆薬線(12)の爆薬線用炸薬(14)の爆発によって主炸薬(16)の爆発が誘発されない。その後、起爆コントローラ(3)は、処理をS103に進める。 In S104, the detonator controller (3) causes the second detonator (18) to detonate the explosive line explosive (14). As a result, the V-groove (13a) of the shaped charge wire (12) becomes a metal jet, protrudes to the outer peripheral side (direction indicated by the arrow X in FIG. 3), and spirally extends to the inner surface of the shell (11) in the circumferential direction. The notch (N) is formed so as to be recessed outward. In FIG. 3, the notch (N) is indicated by a chain double-dashed line. At this time, since the cushioning material (15) is interposed between the main explosive (16) and the shaped charge wire (12), the explosive wire explosive (14) of the shaped charge wire (12) explodes. Explosion of main explosive (16) is not triggered. After that, the detonation controller (3) advances the process to S103.

S104の動作を実行した後の状態で、S103の動作を実行した場合、ノッチ(N)が弾殻(11)の内面に形成された状態で主炸薬(16)が起爆する。このとき、ノッチ(N)周りに応力が集中するので、弾殻(11)がノッチ(N)を境界として破断しやすい。したがって、S104の動作を実行していない状態でS103の動作を行う場合に比べ、弾殻(11)が軸方向に意図したサイズに破断される。 When the operation of S103 is executed after the operation of S104 is executed, the main explosive charge (16) is detonated with the notch (N) formed on the inner surface of the shell (11). At this time, since stress is concentrated around the notch (N), the shell (11) is likely to break with the notch (N) as a boundary. Therefore, the bullet shell (11) is broken to a size intended in the axial direction as compared with the case where the operation of S103 is performed without executing the operation of S104.

一方、S104の動作を実行していない状態で、S103の動作を実行する場合には、弾殻(11)に上述のようなノッチ(N)が形成されていない状態で主炸薬(16)が起爆する。したがって、弾殻(11)が、S104の動作後にS103の動作を行う場合に比べ、ランダムなサイズの破片に破断する。 On the other hand, when the operation of S103 is executed without executing the operation of S104, the main explosive charge (16) is used in a state where the notch (N) as described above is not formed in the shell (11). Detonate. Therefore, the shell (11) breaks into pieces of random size as compared with the case where the operation of S103 is performed after the operation of S104.

このように、第1起爆装置(17)による主炸薬(16)の起爆の前に、第2起爆装置(18)による爆薬線用炸薬(14)の起爆を行った場合と行っていない場合とで、弾殻(11)の破断後の破片形状が異なるので、第1起爆装置(17)による主炸薬(16)の起爆の前に、第2起爆装置(18)による爆薬線用炸薬(14)の起爆を行わせるか否かによって、弾殻(11)の破断後の破片形状を選択できる。 In this way, before the detonator of the main explosive (16) by the first detonator (17), the explosive line explosive (14) was detonated by the second detonator (18) and the case where it was not detonated. Since the shape of the fragments after the shell (11) is broken is different, the explosive line explosive (14) by the second detonator (18) is before the detonation of the main detonator (16) by the first detonator (17). ) Can be detonated, or the shape of the fragment after the shell (11) is broken can be selected.

本実施形態1によると、螺旋状をなす成形爆薬線(12)を1本だけ設けたので、環状の成形爆薬線を複数設ける場合に比べ、弾殻(11)の内側に成形爆薬線(12)を設置する作業が容易になるとともに、部品点数を削減できる。また、各成形爆薬線を起爆させるための第2起爆装置を複数設けなくて良いので、弾頭(10)の構造を簡素化できる。 According to the first embodiment, since only one spiral shaped charge wire (12) is provided, the shaped charge wire (12) is provided inside the shell (11) as compared with the case where a plurality of annular shaped charge wires are provided. ) Can be easily installed and the number of parts can be reduced. Further, since it is not necessary to provide a plurality of second detonators for detonating each shaped charge wire, the structure of the warhead (10) can be simplified.

また、標的の脆弱性に応じて、弾殻(11)の破断後の破片形状を選択できるので、弾殻(11)の破断後の破片形状を、標的に適した形状にできる。 Further, since the shape of the broken pieces of the bullet shell (11) can be selected according to the vulnerability of the target, the shape of the broken pieces of the bullet shell (11) can be made into a shape suitable for the target.

《実施形態2》
図6は、本発明の実施形態2に係る弾頭(10)を示す。本実施形態2では、成形爆薬線(12)が2本設けられている。両成形爆薬線(12)は、全長に亘って軸方向に隣り合うように互いに平行に螺旋状に配設されている。また、第2起爆装置(18)が、成形爆薬線(12)毎に設けられている。
<< Embodiment 2 >>
FIG. 6 shows a warhead (10) according to the second embodiment of the present invention. In the second embodiment, two shaped charge wires (12) are provided. Both shaped charge wires (12) are spirally arranged parallel to each other so as to be adjacent to each other in the axial direction over the entire length. In addition, a second detonator (18) is provided for each shaped charge wire (12).

また、起爆コントローラ(3)が、図7に示すように、S102において、破片サイズの調整が必要であると判定した場合に、S201に進む。そして、S201において、破片の細分化が必要であるか否かを判定する。破片の細分化が必要である場合には、S202に進む一方、破片の細分化が必要でない場合には、S203に進む。ここで、破片の細分化が必要であるか否かの判定は、S101で推定した標的の脆弱性に基づいて行われる。 Further, as shown in FIG. 7, when the detonation controller (3) determines in S102 that the debris size needs to be adjusted, the process proceeds to S201. Then, in S201, it is determined whether or not it is necessary to subdivide the fragments. If it is necessary to subdivide the debris, the process proceeds to S202, and if it is not necessary to subdivide the debris, the process proceeds to S203. Here, the determination as to whether or not the fragmentation of the fragments is necessary is performed based on the vulnerability of the target estimated in S101.

S202では、両第2起爆装置(18)に爆薬線用炸薬(14)を起爆させる。これにより、両成形爆薬線(12)のV溝(13a)が外側に飛び出して弾殻(11)の内面に周方向に螺旋状に延びるノッチ(N)を形成する。その後、S103に進む。 In S202, both second detonators (18) are detonated with explosive line explosives (14). As a result, the V-groove (13a) of both shaped charge wires (12) protrudes outward to form a notch (N) extending spirally in the circumferential direction on the inner surface of the shell (11). Then, the process proceeds to S103.

一方、S203では、両第2起爆装置(18)のうち一方の第2起爆装置(18)だけに爆薬線用炸薬(14)を起爆させる。これにより、一方の成形爆薬線(12)のV溝(13a)が外側に飛び出して弾殻(11)の内面に周方向に螺旋状に延びるノッチ(N)を形成する。その後、S103に進む。 On the other hand, in S203, only one of the second detonators (18) of the two second detonators (18) is detonated with the explosive line explosive (14). As a result, the V-groove (13a) of one of the shaped charge wires (12) protrudes outward to form a notch (N) extending spirally in the circumferential direction on the inner surface of the shell (11). Then, the process proceeds to S103.

S202で両第2起爆装置(18)に起爆を行わせた場合、S203で一方の第2起爆装置(18)だけに起爆を行わせた場合に比べ、ノッチ(N)が弾殻(11)の軸方向により密に形成されるので、弾殻(11)を軸方向により細かく破断できる。このように、両第2起爆装置(18)に起爆を行わせるか、一方の第2起爆装置(18)だけに起爆を行わせるかによって、弾殻(11)の破断後の破片の大きさを選択できる。 When both second detonators (18) were detonated in S202, the notch (N) was the shell (11) compared to the case where only one second detonator (18) was detonated in S203. Since it is formed more densely in the axial direction, the shell (11) can be broken more finely in the axial direction. In this way, depending on whether both second detonators (18) are detonated or only one of the second detonators (18) is detonated, the size of the debris after the shell (11) is broken. Can be selected.

また、上記実施形態1,2では、S102,S201における判定を、標的の脆弱性に基づいて行った。しかし、標的のその他の属性や、弾殻(11)が破壊されているか否か等の弾殻(11)の状態に基づいて行ってもよい。また、ユーザの指令を無線によって受信する受信手段をミサイル(1)に設け、S102,S201における判定を、上記受信手段によって受信された指令に基づいて行ってもよい。 Further, in the first and second embodiments, the determinations in S102 and S201 are performed based on the vulnerability of the target. However, it may be done based on other attributes of the target and the state of the shell (11), such as whether the shell (11) has been destroyed. Further, the missile (1) may be provided with a receiving means for receiving the user's command wirelessly, and the determination in S102 and S201 may be performed based on the command received by the receiving means.

また、上記実施形態2では、弾頭(10)に成形爆薬線(12)を2本設けたが、3本以上の複数設け、第2起爆装置(18)を成形爆薬線(12)毎に設けてもよい。 Further, in the second embodiment, two shaped charge wires (12) are provided on the warhead (10), but a plurality of three or more molded explosive wires (12) are provided, and a second detonator (18) is provided for each shaped charge wire (12).
