Description

  The present invention relates to a warhead, and more particularly, to a type in which a liner is injected by an explosion of a glaze.

  Conventionally, as a warhead of this type, a shell with an opening opened on the front side is filled with glaze, and the opening of the shell is sealed with a liner such as copper, and a liner is formed by the explosive energy of the glaze. There is known an EFP warhead that generates an EFP (Explosively Formed Projectile, or Explosively Formed Penetrator) called a molded bullet, and injects the EFP forward at a high speed so as to hit the target.

  And if the same single EFP warhead can be used to effectively destroy many types of targets, it is highly effective in terms of operation and cost effectiveness.

Conventionally, as a technique to disperse multiple pieces from a single liner, metal wire rods are arranged in a grid on the front side of the liner, and when the liner passes the metal rods at the time of warhead detonation Thus, a method of fragmenting has been proposed (see, for example, Non-Patent Document 1).
“New, Selectable, EFP Warhead Concept”, 41st Annual Bomb & Warhead Technical Meeting (1991)

  However, in the proposed method, when a single EFP is generated from the liner instead of debris, the operator needs to perform a switching operation in which the metal rod is removed in advance. There was a problem that it was difficult.

  The present invention has been made in view of such a point, and the object of the present invention is to devise a single EFP while using a single EFP warhead by modifying the liner dividing means arranged on the liner front side of the warhead. It is to be able to automatically switch between a mode for generating and a mode for fragmenting the liner.

  In order to achieve the above object, in the present invention, the liner dividing means is configured to be erasable, and execution or non-execution of the erasure is switched between two modes by control.

  Specifically, in the first invention, in the EFP type warhead, a liner dividing means for breaking the liner (15) ejected with the explosion of the glaze (13) and dividing it into a plurality of pieces (15B) ( 18), a first mode for keeping the liner dividing means (18) in a non-disappearing state, and a second mode for causing the liner dividing means (18) to disappear so that the liner (15) is not divided into a plurality of pieces (15B). And a mode switching means (28) for switching between and.

  In the second invention, the liner (15) is disposed at the front opening of the shell (1) filled with the glaze (13), and the liner (15) is injected to the target as the glaze (13) explodes. A liner dividing means (18) disposed on the front side of the liner (15) for breaking the liner (15) injected to the target and dividing the liner (15B) into a plurality of fragments (15B); Mode switching means for switching between a first mode for keeping the dividing means (18) in a non-disappearing state and a second mode for causing the liner dividing means (18) to disappear so that the liner (15) is not divided into a plurality of pieces (15B). (28) is provided.

  In the first and second aspects of the invention, when the liner dividing means (18) is switched to the non-erased state or the disappearing state by the mode switching means (28), and the liner (15) is fragmented, the mode switching means (28) Is switched to the first mode, and the liner dividing means (18) is kept in the non-erased state. As a result, the liner (15) injected by the explosion of the glaze (13) is broken when passing through the liner dividing means (18) and divided into a plurality of pieces (15B), and these pieces (15B) are targeted. Sprayed on. On the other hand, when generating a single EFP (15A), the mode switching means (28) switches to the second mode, the liner dividing means (18) disappears, and the liner dividing means ( 18) No state. At this time, the liner (15) injected by the explosion of the glaze (13) is injected as it is without breaking to generate a single EFP (15A). Accordingly, a single EFP warhead can be used to automatically and quickly switch between the generation of a single EFP (15A) by the liner (15) and fragmentation of the same liner (15).

  In the third invention, the liner dividing means (18) is made of MDC. This MDC (Mild Detonation Cord) is called a detonation line and disappears instantly by exploding the internal explosive.

  In the fourth invention, the liner dividing means (18) is made of a metallic tubular body containing explosives. This liner dividing means (18) disappears instantly by exploding the explosives contained in the tubular body.

  According to the third and fourth aspects of the present invention, a suitable liner dividing means (18) that disappears instantly can be obtained easily and specifically.

  In the fifth invention, the liner dividing means (18) has a lattice shape.

  In the sixth invention, the liner dividing means (18) has a mesh shape.

  In the fifth and sixth inventions, the liner (15) can be crushed and divided into a plurality of pieces (15B) having a preferable shape by the liner dividing means (18).

  In the seventh invention, a target identification means (27) for identifying the target type is provided, and the mode switching means (28) switches the mode according to the target type identified by the target identification means (27). It is assumed that

  In the seventh invention, the target type is identified by the target identification means (27), and the mode is switched to the first or second mode according to the identified type. Therefore, the mode switching according to the target is automatically performed. Can be done.

  In the eighth invention, the warhead is mounted on the flying object (33).

  In the eighth aspect of the invention, when the flying object (33) flies and approaches the target, for example, the mode switching means (28) switches the liner dividing means (18) to the non-disappearing state or the disappearing state. For example, a piece (15B) of the liner (15) or a single EFP (15A) is injected from above or the like.

  In the ninth invention, the warhead is installed on the ground.

  In the ninth invention, for example, for a target moving on the ground, in the sky, on the water, in the water, etc., the liner dividing means (18) is switched to the non-disappearing state or the disappearing state by the mode switching means (28). A piece (15B) of the liner (15) or a single EFP (15A) is injected towards it.

  In the tenth aspect of the invention, on the front side of the liner (15) covering the opening to the front side of the shell (1), the disappearance state or non-disappearance based on the detection operation or manual operation of the sensor (25) for identifying the target The MDC that can be switched to a state is arranged in a grid pattern.

  In the tenth aspect of the invention, when the MDC is switched to the non-disappearing state or the disappearing state based on the detection operation or manual operation of the sensor (25) for identifying the target, and the liner (15) is fragmented, the MDC is in the non-disappearing state. The liner (15) to be ejected is broken when it passes through the MDC arranged in a grid and is divided into a plurality of pieces (15B). On the other hand, when the single EFP (15A) is generated, the MDC disappears instantaneously, and there is no MDC on the front side of the shell (1), and the liner (15) is injected as it is without breaking. A single EFP (15A) is generated. This makes it possible to automatically and instantaneously switch between generation of a single EFP (15A) and fragmentation of the liner (15) using a single EFP warhead.

  As described above, according to the first, second, and tenth inventions, it is possible to automatically and instantaneously switch between generation of a single EFP and fragmentation of a liner while using a single EFP warhead. .

  Further, according to the third and fourth inventions, the erasable liner dividing means can be obtained specifically easily.

  According to the fifth and sixth aspects of the invention, the liner is crushed by the liner dividing means to obtain pieces having a plurality of preferable shapes.

The liner (15) seals the opening to the front so that the glaze (13) is filled in the shell (1). The liner (15) has a substantially arc-shaped cross section from the center toward the front. It is curved and its outer peripheral edge is fixed to the inner peripheral surface of the side wall (2) of the bullet shell (1). Without the liner splitting device (18) described later, the explosive of the glaze (13) (warhead ( The liner (15) is ejected as a single EFP (15A) (see FIG. 4 (f)) with the initiation of (A).

  As a feature of the present invention, on the front side of the liner (15), the liner (15) injected to the front side in accordance with the explosion of the glaze (13) is broken to obtain a plurality of pieces (15B) (FIG. 4C). The liner dividing device (18) is divided into a reference end), and the liner dividing device (18) covers the opening of the side wall (2) of the bullet shell (1) and adheres, for example, to the front end surface thereof. It is fixed by mounting. The liner splitting device (18) includes a vertical portion (19) composed of one continuous MDC (explosion line) and a horizontal portion (20). In this MDC, for example, a thin aluminum tube having a wall thickness of about 0.5 mm and an outer diameter of about 3 mm is filled with explosives. The vertical portion (19) and the horizontal portion (20) are, for example, as follows: They are laid out and arranged in a vertical and horizontal grid pattern.

  That is, the vertical portion (19) has one end portion disposed at, for example, the upper end of the side wall portion (2) of the bullet shell (1), and extends from the upper end of the side wall portion (2) along the peripheral edge portion of the side wall portion (2). In FIG. 2, it extends in the counterclockwise direction to about ¼ of the outer peripheral length, and then extends downward in a straight line across the opening of the bullet shell (1), and then on the peripheral edge of the side wall (2). 2 extends in a counterclockwise direction in FIG. 2 and then extends upward in a straight line parallel to the lower straight portion so as to cross the opening of the bullet shell (1), and further along the peripheral edge of the side wall (2). After extending in the clockwise direction in FIG. 2, it extends linearly in parallel with the lower straight part (upper straight part) to cross the opening of the bullet shell (1). 2) extends to the right in FIG. 2 while meandering across the opening in a straight line, and the other end extends down to cross the opening of the shell (1). The The vertical portion (19) is attached and fixed to the front end surface of the side wall (2) at a portion along the peripheral edge of the side wall (2) of the shell (1).

  On the other hand, the lateral portion (20) has one end portion disposed at, for example, the upper end of the side wall portion (2) of the bullet shell (1), and extends from the upper end of the side wall portion (2) to the peripheral edge portion of the side wall portion (2). After extending in the clockwise direction in FIG. 2 by a predetermined length, it extends in a horizontal straight line on the left side of FIG. 2 so as to cross the opening of the shell (1), and then along the peripheral edge of the side wall (2) in FIG. After extending in the counterclockwise direction, it extends in a straight line parallel to the horizontal straight portion on the right side of FIG. 2 so as to cross the opening of the bullet shell (1), and further along the peripheral edge of the side wall portion (2) in FIG. After extending in the direction of rotation, it extends linearly in parallel to the horizontal straight line portion on the left side of FIG. 2 so as to cross the opening of the bullet shell (1), and thereafter crosses the opening of the bullet shell (1) linearly in the same layout. The other end extends to the left side of FIG. 2 so as to cross the opening of the bullet shell (1). The horizontal portion (20) is attached and fixed to the front surface of the vertical portion (19) at the portion intersecting with the vertical portion (19) (therefore, the side wall portion (2) front end surface via the vertical portion (19)).

  The vertical portion (19) and the horizontal portion (20) form a square-shaped mesh having the same size in a portion excluding the peripheral portion, and a substantially triangular or trapezoidal shaped mesh in the peripheral portion. The liner (15) injected to the front side with the explosion of the glaze (13) is broken by the vertical part (19) and the horizontal part (20) which are relatively stationary with respect to the liner (15). A plurality of pieces (15B) are generated at a portion passing through the space between the vertical portion (19) and the horizontal portion (20).

  One end of each of the vertical part (19) and the horizontal part (20) of the liner dividing device (18) is arranged on the outer periphery of the side wall part (2) of the shell (1), for example, at the upper end, for example, from an electric detonator, etc. Connected to the detonator (21). This detonator (21) is accommodated inside the cylindrical body (21a) fixed to the outer peripheral surface of the bullet shell (1) so as to be continuous with the explosives in each one end of the vertical part (19) and the horizontal part (20). By the ignition of this detonator (21), the combustion is transmitted to the explosives in each one end of the vertical part (19) and the horizontal part (20) to explode, so that the liner divider (18) (from the MDC) The vertical part (19) and the horizontal part (20) are blown up and disappeared.

  In addition, a target sensor (25) for identifying the target of the warhead (A) is attached to the lower surface of the outer periphery of the side wall (2) of the shell (1). This sensor (25) consists of an image sensor, an acoustic sensor, a vibration sensor, etc., for example, and the warhead (A) detects a target target and outputs a signal necessary for identifying the type.

  The warhead (A) is provided with a detonation controller (not shown). The sensor (25), the detonator (11) of the warhead (A), and the detonator (21) of the liner splitting device (18) are provided in this controller. In the controller, based on the detection operation of the sensor (25) and the identification result of the target, the vertical part (19) and the horizontal part (20) comprising the MDC of the liner dividing device (18) are Switching to the disappeared state or the non-disappeared state due to non-blasting.

  The processing operation in the controller will be described in detail with reference to FIG. 3. In the first step S1, it is determined whether or not there is target detection by the sensor (25). When the sensor (25) outputs a signal indicating that the target has been detected and the determination is YES, in step S2, based on the detection result of the sensor (25), it is identified whether the target is, for example, a heavy armored vehicle. When this determination is NO (when the target is a light armored vehicle, for example), it is necessary to inject a fragment (15B) instead of a single EFP (15A) on the target, and The mode is shifted to the multi-EFP generation mode (first mode) in which the liner dividing device (18) is maintained in the non-erasure state. In this multi-EFP generation mode, in step S3, the detonator (11) of the warhead (A) is detonated as it is, and the liner (15) that is injected with the explosion of the glaze (13) It breaks by the vertical part (19) and horizontal part (20) which consist of MDC, and divides | segments into several fragments (15B), and these fragments (15B) are sprayed toward a target.

  On the other hand, when the determination in step S2 is YES, it is assumed that it is necessary to inject a single EFP (15A) instead of a fragment (15B) to the target. Transition to one EFP generation mode (second mode). In this single EFP generation mode, first, in step S4, the detonator (21) of the liner divider (18) is detonated. As a result, the explosives in the vertical portion (19) and the horizontal portion (20) made of the MDC explode, and the vertical portion (19) and the horizontal portion (20) disappear due to blasting. Next, the process proceeds to step S5, and when a predetermined time (for example, several tens of microseconds) has passed since the initiation of the liner dividing device (18) (disappearance of the vertical part (19) and the horizontal part (20)), the warhead ( The detonator (11) of A) is detonated, and the liner (15) is injected as it is by the explosion of the glaze (13) to generate a single EFP (15A), and this EFP is made to fly toward the target.

  In this embodiment, the sensor (25) and steps S1 and S2 in the flowchart constitute a target identification means (27) for identifying the type of target.

  Also, in steps S3 to S5, a multi-EFP generation mode (first mode) for keeping the liner dividing device (18) in a non-erased state, and a single EFP generation mode (second mode) for erasing the liner dividing device (18). ) And mode switching means (28) for switching the initiation mode of the warhead (A).

In this mode, the detonator (11) of the warhead (A) is detonated as it is to explode the glaze (13), and the liner (15) that is ejected along with this explosion consists of the MDC of the liner divider (18). It is broken by the vertical part (19) and the horizontal part (20) and divided into a plurality of pieces (15B), and these pieces (15B) are sprayed toward the target.

  On the other hand, when the target is to eject a single EFP (15A), as shown in FIG. 4 (a) → FIG. 4 (d) → FIG. 4 (e) → FIG. ) Is used in the single EFP generation mode (second mode) in which the liner divider (18) disappears. In this single EFP generation mode, the detonator (21) of the liner dividing device (18) is detonated prior to the detonation of the warhead (A). As a result, the vertical part (19) and the horizontal part (20) made of MDC are blown out by the explosion of the internal gunpowder and disappear without damaging the other parts of the warhead (A). Subsequently, when a predetermined time (for example, several tens of microseconds) elapses, the detonator (11) of the warhead (A) is detonated and the glaze (13) explodes, and the liner (15) is broken and broken by this explosion. Without being injected, a single EFP (15A) is generated, and this EFP (15A) flies toward the target.
