Description

  The present invention relates to a rocket-mounted child bullet emitting device used to discharge a bullet loaded on a rocket at a destination.

  As a conventional rocket-mounted bullet discharge device, there are those equipped with a plurality of stages of combustors arranged in series on an axle, a discharge explosive arranged at the end of each combustor, and its igniter. Each combustor is provided with a gas injection hole communicating with the inside of each container, and a container containing a plurality of bullets is disposed around the combustor. In this rocket-mounted shell release device, an explosive is ignited by an igniter, the combustion gas is injected from a gas injection hole, and a bullet is released by the pressure of the combustion gas.

In addition, the other rocket-mounted unit bullet discharge devices are equipped with a combustor similar to the above-mentioned device and a container for the unit bullets, and provided with a point-in-time fire mechanism that sequentially burns the explosives discharged from each combustor (patents) There are some which operate the first-stage combustor and sequentially operate the second-stage and lower combustors using the combustion gas (see Patent Document 2).
British Patent No. 1434034 JP 2004-44884 A

  However, in the conventional rocket-mounted shell release device, each explosive is loaded with explosives and individually ignited, or the explosive explosives of each combustor are sequentially burned by a time-ignition mechanism. In either case, the structure tends to be complicated, and there has been a demand for improvements in the simplification of the structure and the improvement of the operation reliability.

  The present invention has been made in view of the above-described conventional situation, and an object of the present invention is to provide a rocket-mounted reaming device capable of realizing a simplified structure and improved reliability.

  The rocket-mounted child bullet discharge device of the present invention is a device for discharging a bullet loaded on a rocket, and includes a combustor loaded with explosives for discharging a bullet and a bullet housing chamber in which a bullet is releasably accommodated. In addition, the combustor and the shell housing chamber are in communication with each other through the gas injection hole, and the combustion chamber is provided with a linearly held explosive wire and its igniter, and around the explosive wire. The explosive for expelling ammunition is arranged, and the above-mentioned constitution is used as a means for solving the problem.

  According to the rocket-mounted bullet discharge device of the present invention, the structure can be greatly simplified and the reliability of operation can be further improved. With these advantages, a plurality of bullets can be loaded and discharged. Can also be easily dealt with.

Hereinafter, an embodiment of a rocket-mounted reaming device of the present invention will be described with reference to the drawings.
A rocket-mounted shell release device 1 shown in FIG. 1 releases a plurality of slave bullets S mounted on a rocket R, and releases a combustor 3 loaded with explosives 2 for releasing a bullet, and a bullet S. It has a structure in which a bullet housing chamber 4 that can be accommodated is provided, and the inside of the combustor 3 and the bullet housing chamber 4 are in communication with each other via a gas injection hole 5.

  The rocket-mounted shell discharge device 1 of this embodiment has three combustors 3 arranged in series on the axis L of the rocket R, and three flat cylindrical containers C centering on each combustor 3. I have.

  The container C has a plurality of bullet housing chambers 4 in the circumferential direction, and is arranged side by side in the axis direction of the rocket R. Thereby, the bullet housing chambers 4 are arranged in the axis direction and the circumferential direction of the rocket R.

  Each of the bullet housing chambers 4 accommodates the bullet S in a releasable manner, and is provided with an outer plate or the like that can be opened or separated at the outer periphery of the rocket. As described above, by arranging the bullet housing chambers 4 in the axial direction and the circumferential direction of the rocket R and housing the bullets S, it is possible to more effectively spray the bullets S. The secondary bullet S may be held in the secondary bullet storage chamber 4 with, for example, a shear pin.

  Each combustor 3 is a cylindrical container and is connected in order. As shown in FIG. 2, the explosion line 6 is held linearly on the center line. The explosive wire 6 is a common component that is continuous with each combustor 3 and is mounted in a state of penetrating the center of each combustor 3.

  In the combustor 3 on the left side of the rocket head in FIG. 1, an igniter 7 is provided at the end of the explosive wire 6. In each combustor 3, a child is disposed around the explosive wire 6. An explosive for explosive discharge 2 is arranged. The gas injection holes 5 are provided in the combustor 3 at positions where they do not interfere with the explosives 2 for releasing the bullets.

  In the rocket-mounted bullet discharge device 1 having the above-described configuration, when the rocket R flies and reaches the destination, the explosive wire 6 is detonated by the igniter 7 and the child of each combustor 3 is used by the explosion energy. The bullet explosive 2 is ignited almost simultaneously. Thereby, in each combustor 3, the combustion gas of the explosives 2 for ejecting the bullets is injected from the gas injection holes 5, and the bullets S are simultaneously released from the respective bullet storage chambers 4 by the pressure.

  As described above, the above-described rocket-mounted bullet discharge device 1 has a very simple structure because the ignition system includes only one igniter 7 and one explosive wire 4 regardless of the number of combustors 3. And it is excellent in productivity. Moreover, since the burning speed of the detonation wire 6 is very fast, even when operating the plurality of combustors 3, the uniformity is excellent and the operation reliability is extremely high.

  By the way, as described above, a discharge device using an explosion line in an ignition system, for example, when scattering a large number of small pieces or powders such as a radar chaff, removes small pieces or powders only by the explosion energy of the explosion line. Although it is possible to make the structure to be scattered, it is difficult to release a bullet having a mass obviously larger than these at a sufficient speed.

  On the other hand, the rocket-mounted bullet discharge device 1 releases the bullets S at a sufficient speed by disposing the explosives 2 for discharging the bullets around the detonation wire 6 in each combustor 3. It is possible to generate the pressure of the combustion gas necessary for this.

  FIG. 3 is a view for explaining another embodiment of the rocket-mounted bullet discharge device of the present invention. Note that the same components as those of the previous embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the illustrated embodiment, the rocket-mounted bullet release device 1 is loaded with the same amount of explosives 2 for ejecting bullets in each combustor 3, whereas the explosives for ejecting bullets in each combustor 3 are shown in FIG. The amount of 2 is different. In this embodiment, the amount of explosives 2 for releasing the bullets is increased in order from the rocket head side on the left side in FIG.

  The above-described rocket-mounted bullet discharge device 1 can obtain the same operation and effect as the previous embodiment, and also has a different amount of the bullet discharge explosives 2 in each combustor 3, In particular, when the amount of explosives 2 for increasing the number of bullets is increased in order as shown in the drawing, the discharge distance increases as the latter stage is reached. S can be effectively dispersed without interfering with each other.

  In addition, the structure of the rocket-mounted bullet discharge device according to the present invention is not limited to the above embodiment, and for example, the configuration details such as the shape and number of the combustor and the bullet storage chamber may be changed as appropriate. Can do.

It is a sectional view of an important section explaining one embodiment of a rocket loading bullet discharge device of the present invention. It is an expanded sectional view of a combustor. It is sectional drawing of the principal part explaining other embodiment of the rocket on-board bullet discharge apparatus of this invention.
