Description

       

  Bombe d'exercice pour mortier.

  
La présente invention se rapporte à une bombe destinée aux exercices de tir au mortier.

  
Pour les exercices de tir au mortier, on utilise

  
 <EMI ID=1.1> 

  
laires qui ont l'inconvénient de se rompre quand elles sont projetées ou quand elles touchent le sol. Il est impossible par conséquent d'utiliser la même bombe plus d'une fois et, en outre, même si la bombe n'est pas détruite, elle se perd très souvent, car rien ne dénonce son point de chute, sauf un soulèvement de terre momentané qui se produit au moment du contact avec le sol.

  
La bombe d'exercice selon l'invention comprend un corps creux partiellement rempli d'une substance de ballast et est caractérisée en ce qu'elle présente au moins une ouverture dans la partie avant de la paroi du corps, communiquant avec une chambre comprise à l'intérieur de ce corps, &#65533;=&#65533; 

  
un couvercle placé à la partie avant du corps et fermant la dite ouverture, une fusée et une charge explosive dans la dite chambre, qui détone sous l'action de la dite fusée

  
 <EMI ID=2.1> 

  
s'échappant par la dite ouverture en déformant le couvercle, qui prend ainsi une forme empêchant la pénétration de la bombe dans le sol au lieu de percussion, pour permettre la récupération du corps susdit.

  
La bombe selon la présente invention présente l'avantage que son corps au moins est récupérable et utilisable un grand nombre de fois pour les exercices de tir, permettant ainsi d'assurer l'instruction des servants de mortiers avec une dépence très réduite. Ce type de bombe peut être fabriqué dans n'importe quel calibre.

  
Cette bombe est projetée de la même manière que les bombes normales.

  
La figure unique du dessin annexé représente, à titre d'exemple, une forme d'exécution de la bombe objet de l'invention, vue en coupe longitudinale.

  
La bombe comprend un corps 1 pourvu à sa partie supérieure (ogive) de plusieurs ouvertures 2 qui communiquent avec la partie intérieure du corps. L'espace compris dans ce dernier est rempli en partie par du lest 3, maintenu en place par du plomb ou une matière similaire 4, ce

  
lest étant prévu pour donner à la bombe un poids normal.

  
Sur cet élément de retenue 4 on dépose une petite cartouche 5 d'un explosif approprié, par exemple de la poudre noire ou de la poudre à base de nitrocellulose. La bombe comporte

  
une fusée 6, de préférence une fusée normale du type instantané, sans détonateur. Cette fusée est vissée sur le corps et sert à fixer un couvercle 7 en métal laminé qui couvre la partie supérieure ogivale du corps et ferme hermétiquement



  Exercise bomb for mortar.

  
The present invention relates to a bomb intended for mortar firing exercises.

  
For mortar firing exercises, we use

  
 <EMI ID = 1.1>

  
strips which have the disadvantage of breaking when they are thrown or when they hit the ground. It is therefore impossible to use the same bomb more than once and, moreover, even if the bomb is not destroyed, it gets lost very often, because nothing denotes its point of fall, except an uprising of momentary earth that occurs upon contact with the ground.

  
The exercise bomb according to the invention comprises a hollow body partially filled with a ballast substance and is characterized in that it has at least one opening in the front part of the wall of the body, communicating with a chamber included in inside this body, &#65533; = &#65533;

  
a cover placed at the front part of the body and closing said opening, a rocket and an explosive charge in said chamber, which detonates under the action of said rocket

  
 <EMI ID = 2.1>

  
escaping through the said opening by deforming the cover, which thus takes a shape preventing the penetration of the bomb into the ground instead of percussion, to allow the recovery of the aforesaid body.

  
The bomb according to the present invention has the advantage that its body at least is recoverable and usable a large number of times for shooting exercises, thus making it possible to ensure the instruction of mortar gunners with a very low expenditure. This type of bomb can be made in any caliber.

  
This bomb is thrown in the same way as normal bombs.

  
The single figure of the appended drawing represents, by way of example, an embodiment of the bomb object of the invention, seen in longitudinal section.

  
The bomb comprises a body 1 provided at its upper part (warhead) with several openings 2 which communicate with the interior part of the body. The space included in the latter is partially filled with ballast 3, held in place by lead or a similar material 4, this

  
ballast being provided to give the bomb a normal weight.

  
On this retaining element 4 is deposited a small cartridge 5 of a suitable explosive, for example black powder or powder based on nitrocellulose. The bomb has

  
a fuse 6, preferably a normal fuse of the instantaneous type, without a detonator. This rocket is screwed onto the body and is used to fix a laminated metal cover 7 which covers the ogival upper part of the body and closes tightly

Claims

the openings 2. The cover has on its front part

an inwardly directed flange which is clamped between the front surface of the bomb body and the opposing surface

of the rocket. To make the closure more perfect, the

body of the bomb comprises a groove 8, immediately above the striped part of the body indicated by 9, this groove 8 receiving the free edge of the cover 7. It is also placed inside the body, for example next to the cartridge 5, a smoke-producing substance intended to produce smoke for a relatively long time. The body of the

bomb is of the type of war bombs and resists the maximum pressure which is established in the mortars. Finally, a coat of varnish is applied to the joints.

In almost all cases, the body and tail of the bomb can be recovered, as are most parts of the rocket.

It is understood that the present invention is in no way limited to the example described and shown, various modifications of shape and / or detail being able to be made without departing from the scope of the invention.

CLAIMS.

1.- Exercise bomb for mortar, comprising a hollow body partially filled with a ballast substance, characterized in that it has at least one opening in the front part of the wall of the body, communicating with a chamber included in inside this body, a cover placed

the front part of the body and closing it. called opening, a

rocket and an explosive charge in said chamber, which detonates under the action of said rocket when the bomb strikes, the gases produced by the explosion escaping through said opening, deforming the cover, which thus takes a shape preventing the penetration of the bomb into the ground instead of percussion,

to allow recovery of the aforesaid body.
