  However, in the liquid retraction method described in the above-mentioned Patent Document 1, when an empty hose is projected by a rocket bullet, an event such as twisting or folding of the hose occurs, and liquid fuel is supplied to the hose. There is a possibility that the injection cannot be performed smoothly.

  In addition, since a fuel filling device for injecting liquid fuel into the hose is required, the system becomes larger, and the process of filling the liquid fuel after projecting and expanding an empty hose is essential, so it is responsive. Has the disadvantage of lacking.

On the other hand, it has sufficient strength against the tension caused by projection / expansion in a state filled with liquid fuel in advance, and has sufficient flexibility / flexibility for storage / projection to lifting. It is difficult to use a hose structure / material.
At the time of projection / lifting, the liquid fuel oscillates within the long hose, so that the rocket projectile cannot be stably projected.
If a liquid fuel having a degree of freedom in a long hose is subjected to sudden adiabatic compression due to the acceleration of firing, there is a risk of explosion.

  Therefore, the present invention does not need to fill the sleeve with liquid fuel after the projection, and has a flexible, flexible, and a stable and safe flight, and can reduce the size and weight of the system configuration. The purpose is to provide an explosive projection system using this.

The explosive line for solving the above-mentioned problems is used for projecting to explode landmines in a minefield, and a plurality of powerful bodies filled with liquid fuel in a case are formed in a cylindrical sleeve. It is characterized in that a shock-absorbing member that relaxes the contact force applied to these powerful bodies is interposed between the adjacent powerful bodies .
A detonation projection system for solving the above-described problem is characterized by having the detonation described above, a rocket for coasting the detonation, and a launching device for firing the rocket.

According to the present invention, it is not necessary to fill the liquid fuel to the sleeve after the projection, flexibility, stability has flexibility and flying, it is possible to reduce the size and weight of the system configuration with safety, also , by the buffer member, Ru can be relaxed abutment force applied to power body adjacent to each other.

  As shown in FIG. 1, the explosive projection system 1 includes an explosive A according to an embodiment of the present invention, a rocket 2 for coasting the explosive A, and a launching device 3 for firing the rocket 2. doing.

  The launching device 3 has a function of launching the rocket bullets 2 and is reduced in size by adopting a simple configuration that eliminates a filling mechanism for injecting liquid fuel into the sleeve 10 to be described later. is there.

As shown in FIG. 2, the explosive A according to the embodiment of the present invention mainly includes a sleeve 10, a power body 20, a buffer member 30, a connection band 40, and a detonation / priming agent 50.
The sleeve 10 has a cylindrical shape having a required inner diameter of about several tens of millimeters and a predetermined length of about several tens of meters.
The sleeve 10 has a strength that can withstand the cable tension during projection. Specifically, it is made of a material such as Kevlar having a strength capable of withstanding an external force received from the rocket bullet 2 that coasts the explosive A.

As shown in FIGS. 2 and 3A to 3C, the powerful body 20 shown in the present embodiment is a liquid fuel F filled in a case 21 and sealed.
“Liquid fuel F” is, for example, nitromethane, propylene oxide, or the like.
The case 21 shown in this embodiment is made of metal, has a cylindrical shape with a required length L, and has an outer diameter D slightly larger than the inner diameter of the sleeve 10.
Specifically, it has a substantially spherical shape in which end wall portions 21b and 21b formed as convex curved surfaces are combined on both sides of the central wall portion 21a having a constant outer diameter.

  A part of the case 21 is formed with a filling hole for filling the liquid fuel F and an air vent hole (both not shown), and before the power body 20 is loaded into the sleeve 10 described above. The liquid fuel F is filled.

Through holes 21c and 21c are formed in the end wall portions 21b and 21b so as to penetrate the explosive / primer 50 in alignment with the axis O of the central wall portion 21a.
In addition, on the outer wall surfaces of the end wall portions 21b and 21b, four hooking protrusions 22 for hooking the connecting band 40 at intervals of 90 degrees are provided at opposite positions on both sides of the axis O.

As shown in FIG. 2, the connecting band 40 is for elastically connecting the power bodies 20 and 20 with the following buffer members 30 interposed between the power bodies 20 and 20 adjacent to each other. For example, it is formed of a rubber material.
In the present embodiment, the hooking holes 41 and 41 for inserting and hooking the hooking protrusions 22 are formed at a required length for elastically connecting the adjacent power bodies 20 and 20 to each other at both ends. Has been drilled.
