Abstract

The present invention belongs to the sector of conventional infantry weapons. Its subject is a spin projectile comprising a one-piece part which has radial tail fins and which contains a standard propellant mortar cartridge and which withstands the explosion of the latter. This projectile is inexpensive, ensures accurate firing and is especially suitable for exercise firing.

Description

Le present certificat d'addition se rapporte à la demande de brevet
d'invention ayant pour titre "Projectile économique pour mortier
déposée en France le 21 mars 1984 sous le numéro 8404369, l'invention se
situant dans le secteur des munitions conventionelles d'infanterie.This certificate of addition relates to the patent application
with the title "Economic projectile for mortar
filed in France on March 21, 1984 under number 8404369, the invention is
located in the sector of conventional infantry ammunition.

Ce certificat concerne un mode de réalisation original de l'invention
principale, laquelle porte sur un projectile équipé d'une cartouche
standard pour le type de mortier utilisé, l'invention étant caractérisée
essentiellement en ce que la partie arrière du projeotile constitue une
queue monobloc 2 contenant ladite cartouche en 3 et comportant extérieu
rement des ailettes radiales 5, et en ce que sa partie avant constitue
un corps monobloc 1 comportant extérieurement des ceintures il au calibre
du mortier et axialement à l'avant un orifice 13 à obturer.This certificate relates to an original embodiment of the invention
main, which relates to a projectile equipped with a cartridge
standard for the type of mortar used, the invention being characterized
essentially in that the rear part of the projeotile constitutes a
monobloc tail 2 containing said cartridge in 3 and comprising exterior
rement of the radial fins 5, and in that its front part constitutes
a monobloc body 1 externally comprising belts il of caliber
mortar and axially at the front an orifice 13 to be closed.

La présente addition concerne une possibilité de communication
entre le corps 1 et la queue 2.This addition concerns a possibility of communication
between body 1 and tail 2.

La figure 3 est une coupe axiale correspondant à la vue longitudinale
de la figure 1 du brevet.Figure 3 is an axial section corresponding to the longitudinal view
of Figure 1 of the patent.

Cette coupe montre, à titre d'exemple comment la cloison 15 séparant
le corps 1 et la queue 2 peut s'ouvrir en 16 sous l'effet de la pression
des gaz produits par la déflagration de la cartouche propulsive.This section shows, by way of example how the partition 15 separating
body 1 and tail 2 can open at 16 under the effect of pressure
gases produced by the explosion of the propellant cartridge.

L'amorce de rupture de la cloison 15 est obtenue notamment par
usinage, sertissage, collage ou amincissement de la cloison.The initiation of rupture of the partition 15 is obtained in particular by
machining, crimping, gluing or thinning of the partition.

Ainsi, les gaz enflammés de cette déflagration peuvent pénétrer
dans le corps 1 et allumer un dispositif pyrotechnique quelconque
(fumigène, lacrymogène etc.) sans avoir à y incorporer un dispositif de mise à feu. Thus, the inflamed gases of this deflagration can penetrate
in body 1 and ignite any pyrotechnic device
(smoke, tear gas etc.) without having to incorporate a firing device.

Claims (2)

REVENDICAT10s S 1. Projectile selon la revendication 1 du brevet principal, caractérisé en ce que sa partie avant constitue le corps du projectile et e ce que la cloison de séparation entre la queue et le corps s'ouvre sous l'effet de la pression des gaz produits par la déflagration de la cartouche propulsive. 1. Projectile according to claim 1 of the main patent, characterized in that its front part constitutes the body of the projectile and e that the partition between the tail and the body opens under the effect of the pressure of the gases produced by the deflagration of the propellant cartridge. 2. Projectile selon la revendication 1, caractérisé en ce que chaque ailette de la queue monobloc a une base incurvée latéralement de façon continue et quelconque.  2. Projectile according to claim 1, characterized in that each fin of the monobloc tail has a curved base laterally continuously and arbitrarily.
