Description

[Detailed description of the invention] This invention relates to an aerial barrage bullet used for special filming for movies, television, etc. More specifically, colored powder is filled into a glass hollow spherical shell with a diameter of 40 mm or less. This invention also relates to an aerial barrage projectile constructed by loading an explosive device into the center of the colored powder.

Previously, this type of aerial barrage projectile used so-called fireworks, so when they were launched into the air and exploded, the paper shell would become debris and fall like a cocoon, so this was photographed. In this case, there was a drawback that the screen effect was significantly impaired.

This invention is a completely new projectile that fundamentally improves the shortcomings of the conventional projectiles.In particular, when the projectile explodes, the remains of the shell are scattered as fine powder so that they cannot be identified with the naked eye. This is about the bullet that made this possible.

One embodiment of the present invention will be explained in detail with reference to the drawings. In the drawing, A is a glass bulb outer shell with a diameter of 30 m and a thickness of 0.05 mm, and inside the glass bulb outer shell A is a dye, A colored powder 1 such as pigment 9 and colored cement is filled, and an explosive charge 2 is further charged in the center of the colored powder 1.

3 is an ignition charge, and the ignition charge 3, the explosive charge 2, and the time delay conductor 4 are connected to each other.

The glass bulb outer shell A used in the above embodiment preferably has a wall thickness that allows it to be scattered into extremely small pieces in the event of an explosion, and according to the inventor's experiments, it is ideally 0.1 rran or less; If the thickness is 001 m or less, the diameter of the outer skin A must be less than 40 m1, and it has been found that if the diameter is greater than this, there is a risk that the outer skin A may be damaged when the projectile is launched.

When a bullet satisfying the above-mentioned conditions for the glass bulb outer shell A was used, the outer shell A was scattered extremely finely upon explosion so that it could not be discerned with the naked eye, and good results were obtained.

As mentioned above, the projectile according to the present invention uses a glass bulb outer shell, so when it explodes, it scatters finely and cannot be seen with the naked eye or through a lens, and the outer shell becomes debris and falls like a cocoon, as in the past. There is no fear, and the glass bulb envelope is 40m long enough to be launched even with an extremely thin wall thickness.
The diameter of the projectile is less than 1.5 m, so the launch process is simple and reliable.The shell is thin, so the shell can be dispersed as extremely fine powder when it explodes, and there are no pigments, etc. Since it is filled with colored powder, it has various effects such as being able to effectively scatter this powder over a wide range when it explodes.
