Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projectile having a core, and when the target is reached, the projectile is adapted to penetrate the target by the kinetic energy at that time.

[0002]

2. Description of the Related Art Conventionally, as the above-mentioned flying body, for example, there is one shown in FIG.

A flying body 51 shown in the figure has a motor portion 5 inside a case 52 as a thrust source for generating a flying thrust.
3 and the case 52, a core 54 having a diameter considerably smaller than that of the case 3 and the case 52 is housed, and the core 54 is located at the head of the case 52 partitioned by a partition wall 52a.

The projectile 51 gives all the kinetic energy that it has at the time of reaching the target to the small-diameter core 54 so that the core 54 rushes into the target.

This projectile 51 is an INTERAVIA
3/1986.

[0006]

However, in the conventional flying body 51 described above, when the launcher launches at high speed,
Since the impact load applied to the core 54 transmitted through the partition wall 52a is received by the entire case 52, the case 5
It was necessary to make the No. 2 a robust structure that can withstand buckling, which necessitated an increase in weight.

Further, since the core 54 is housed separately in the head of the case 52, there is a problem that the flying body 51 becomes large accordingly.

Further, in the flying object 51, when it reaches the target, it collides from the core 54, so that it may not be possible to penetrate the target having a bulletproof steel plate having explosive charge on its surface, for example. There is a problem that there is, and it has been a conventional problem to solve these problems.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art, and provides a flying body which can be made small and lightweight, and which can surely penetrate a target. Is intended.

[0010]

SUMMARY OF THE INVENTION According to the present invention, in a projectile in which a thrust source for generating flight thrust and a core are housed inside a case, when the core is positioned on the tail side of the case, the target is reached. It is characterized by being configured to support kinetic energy so that it can move in the flight direction,
Such a structure of the flying body is used as a means for solving the above-mentioned conventional problems.

Further, in one embodiment, the thrust source is provided with a sustainer propellant.

[0012]

In the projectile according to the present invention, since the core is located on the tail side of the case, the total length is short, and when the launcher fires at high speed, the core hits the core. Since the impact load is received only on the tail side of the case, it is not necessary to make the entire case a solid structure,
Therefore, the size and weight of the case can be reduced.

Further, when the target is reached, since the bullet core collides with the head of the case after a short time, the collision occurs.
For example, for a target having a bulletproof steel plate equipped with an explosive charge on the surface, the bullet core maintains the kinetic energy and collides with the bulletproof steel plate after removing the explosive charge on the surface with a case. It's easier to stick to your goals.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

1 to 6 show an embodiment of a flying object according to the present invention.

As shown in FIG. 1, this flying body 1 has a motor case 1 in which a solid propellant (booster booster propellant and sustainer propellant) 2 as a thrust source for generating flying thrust is produced.
No. 12 and stabilizing vanes 1 are provided in the tail portion 11 of the motor case 10 by filling the interior of the motor case 10 over almost the entire length.
4 is provided.

Further, the flying body 1 is provided with a penetrator (bullet core) 3 made of tungsten. In this embodiment, the penetrator 3 is in the form of a rocket, and its diameter is significantly smaller than the diameter of the motor case 10. The tail portion has four fixed blades 3a at 90 ° intervals. It is arranged. In this case, the tail portion 11 of the motor case 10 is, as shown in an enlarged manner in FIGS. 2 to 4, a cylindrical portion 13a which is located on the axis of the motor case 10 and which fits and supports the tail portion of the penetrator 3.
A heat-resistant penetrator support portion 13 including a groove portion 13b, which is arranged around the cylindrical portion 13a at an interval of 90 ° and supports and fixes the fixed blade 3a, is integrally provided. 3 is supported on the axis of the motor case 10 by fitting the tail portion to the cylindrical portion 13a of the penetrator support portion 13 and fitting the four fixed blades 3a to the groove portions 13b, respectively. I am doing it. The penetrator 3 is separably fixed to the motor case 10 by fitting the shear pin 4 penetrating the cylindrical portion 13a of the penetrator support portion 13 into the tail portion.

That is, the penetrator 3 is fixed to the tail portion 11 of the motor case 10 by the penetrator support portion 13 and the shear pin 4 at the stage of being launched and flying, and at the stage of reaching the target, the shear pin 4 is cut by inertial force. The kinetic energy at this time is maintained to move in the flight direction.

As shown in FIG. 5, this projectile 1 is launched by a launcher 5 with a large initial velocity (T1 in the figure) and accelerated by the combustion of the booster propellant component of the solid propellant 2 (in the figure). At the same time as T2), the velocity is maintained (T3 in the figure) by the combustion of the sustainer propellant component of the solid propellant 2 and the aircraft flies to reach the target 20 (T4 in the figure).

During this time, the penetrator 3 is connected to the motor case 1 by the penetrator support portion 13 and the shear pin 4.
Since it is fixed to the tail portion 0 of 0, the impact load applied to the penetrator 3 at the time of firing or acceleration does not reach the entire motor case 10, and the penetrator support portion 1
Since 3 is heat-resistant, it does not hinder the support of the penetrator 3.

When the target 20 is reached (T4 in the figure), as shown in FIG.
The head side collides and causes damage. At this moment, the penetrator 3 moves by the inertial force, so that the shear pin 4 is moved.
Is cut to separate from the penetrator support 13.

Next, the penetrator 3 maintains the kinetic energy at this time and moves in the flight direction, and the bulletproof steel plate 21 damaged by the collision of the motor case 10.
Through.

At this time, even if the target 20 is a bulletproof steel plate 21 provided with an explosive charge 22 on its surface so as to induce the penetrator 3 to explode by a sensor (so-called reactive armor), the motor case 10 After the explosive charge 22 on the surface is removed by the collision, the penetrator 3 maintains the kinetic energy and collides with the bulletproof steel plate 21, so that the penetrator 3 surely penetrates the target.

Further, in this embodiment, since the solid propellant 2 having the sustainer propellant component is used as the thrust source, the high velocity is maintained until the projectile 1 reaches the target 20. Therefore, the damage given to the target 20 by the collision of the motor case 10 becomes large.

Therefore, in this flying vehicle 1, since the penetrator 3 is fixed to the tail portion 11 of the motor case 10, the total length can be shortened, and the impact load applied to the penetrator 3 at the time of launching or accelerating the motor case 10 can be reduced. Since it is not received as a whole, it is not necessary to have a robust structure,
The weight will be reduced.

Next, when the total weight of the flying body 1 and a flying body having a conventional core on its head were compared, the results shown in FIG. 7 were obtained.

As a result, for example, in order to obtain the same increase speed of 7 Mach after launch, the flying body 1 which does not require a robust structure has a fully equipped weight of about 43 × 9.8 N, whereas It was found that the total weight of the flying body was about 90 × 9.8 N, and it was proved that the flying body 1 is significantly lighter than the conventional flying body.

The detailed structure of the flying object according to the present invention is not limited to the above embodiment.

[0029]

As described above, according to the flying object of the present invention, since it has the above-described structure, the total length is short and the case does not need to have a solid structure.・ It is possible to reduce the weight, and at the time of reaching the target, the bullet collides with the head of the case after a short period of time, so that it is possible to reliably penetrate the target. Has an excellent effect on.
