Definitions
- the present invention relates to a pyrotechnic projectile whose orientation is predetermined at the time of its explosion.
- Another technique for orienting a projectile is to use a self-propelled object.
- the invention consists in producing a projectile fired from a mortar, which is oriented in a predetermined direction at the time of its explosion and does not generate blunt fallout likely to cause damage to property or people.
- a pyrotechnic projectile comprising a body containing a bursting charge and a combustible charge intended for the creation of an artifice effect, characterized in that the nose of the body of the device contains a mass of material high density powder to move the center of gravity of the projectile forward, breaking the body and nose caused by the explosion of the bursting charge ensuring the dispersion of the powder in the atmosphere.
- Fig.l is a perspective view with partial cutaway of the projectile next pyrotechnic
- the invention; and - Fig.2 is a sectional view on a larger scale of the pyrotechnic projectile of Figure 1.
- a tubular body 1 made of plastic comprising a head 2 and with which is associated a skirt 3 forming a tail.
- a bursting charge 4 consisting for example of black powder within which is disposed a combustible charge 5 which in the present example is formed of particles of metal such as titanium agglomerated.
- the combustible charge can also be formed from non-agglomerated metal particles judiciously arranged to obtain the desired pattern.
- the body 1 is closed by a cover 6 on which is mounted a container 7 of frustoconical shape and which defines the nose of the projectile.
- the cover 6 forms the base of the container 7.
- a mass 8 of high density metal powder for example iron powder intended to make the head of the projectile heavier and to move its center of gravity forward.
- the body 1 comprises an axial tubular sleeve 9 integrally formed with its bottom
- the sleeve 9 opens out at the center of the skirt 3 forming a tail.
- elongated openings 12 for maintaining the trajectory of the projectile after its launch.
- the tubular body 1, the skirt 3, the cover 6 of the body 1 and the container 7 forming the nose of the projectile are made of plastic material, for example made of polystyrene and fixed together by gluing.
- the skirt 3 is made so as to have sufficient strength not to be destroyed by the projectile launcher, but fragile enough to be reduced like the rest of the projectile envelope into small pieces at the time of the explosion of the craft.
- the nose 2 and the skirt 3 can be an integral part of the body 1 and the mass of iron powder 8 as well as the bursting and combustible charges can be placed successively in the body with the interposition of a partition wall and a bottom provided with an axial sleeve for the pyrotechnic delay.
- the bursting charge 4 has three functions. It causes the explosion of the machine and it ignites and disperses the titanium particles of the fuel charge 5.
- the pyrotechnic delay is a delay of 1 order
- the combined action of the ballast constituted by the mass of iron powder 8 placed in the nose of the projectile and elongated openings 12 formed in its skirt 3 ensures the maintenance of the axis of the projectile on the trajectory which it is intended to follow .
- the bursting charge 4 ignited by the pyrotechnic delay 11 there is destruction of the body 1, of the nose 2 and of the plastic skirt 3, ignition and dispersion of the agglomerated particles of the combustible charge 5 and dispersion of the mass of iron powder 8 which falls without causing the slightest risk of deterioration of objects or injury to persons.
