Abstract

The explosive shell with different charges, is enclosed by a detachable sleeve matching its shape. The sleeve has longitudinal grooves or other weak zones, for disintegration soon after firing. The bottom of the sleeve interlocks with a base which also forms a connection with the bottom of the shell. - The shell can be one of two specified types, and can have an explosive charge behind at least one incendiary charge. The explosive charge is not detonated by a fuse and is detonated after a delay.

Description

       

  Obus à effets combinés Obus à effets combinés.

  
L'invention concerne un obus à effets combinés.

  
On connaît déjà des obus à sabot détachable APDS (Armour Piercing Discarding Sabot) consistant substantiellement en

  
un noyau sous-calibré en métal lourd et un sabot qui se détache quand l'obus quitte le canon.

  
L'un des grands avantages d'un tel obus est que le temps de vol pour une distance donnée, en comparaison à un obus classique, est plus court en raison de la vitesse initiale plus élevée et du rapport de la masse du noyau par unité de surface transversale.

  
Un autre avantage de ces obus se trouve dans leur effet perforant élevé, ceci par suite du rapport favorable de l'énergie disponible par unité de surface transversale du noyau.

  
Toutefois l'inconvénient de cet obus est que l'effet en cible se limite à un effet perforant ou perforant/incendiaire.

  
On connaît également des obus multipurpose ou PIE (Pyrotechnically Initiated Explosive), notamment des obus à effets combinés ou multiples, de forme extérieure semblable aux obus classiques, sans fusée habituelle. Ces projectiles sont caractérisés en ce que l'effet de fragmentation est obtenu par l'intermédiaire d'une charge explosive disposée derrière des charges incendiaires, cette charge explosive pouvant détoner sans aucun moyen fusant et ne détonant qu'après un certain retard. Un exemple d'un tel obus est décrit dans le brevet belge no 740.309. Une autre configuration d'un tel obus est décrite dans le brevet belge no 856.378.

  
Un premier avantage de ce type d'obus est son effet multiple; il présente notamment, à la fois, un effet perforant, incendiaire et explosif (fragmentation).

  
Un autre avantage de cet obus se trouve dans le fait que les effets explosif et incendiaire sont retardés, ce qui influence favorablement l'efficacité de l'obus surtout dans le cas du tir contre véhicules légèrement blindés et contre aéronefs.

  
Un autre avantage encore réside dans le fait que le prix de

  
ce type d'obus est relativement réduit en raison de l'absence d'une fusée.

  
Les inconvénients d'un tel obus multipurpose sont, en ordre principal, que l'obus est relativement lent, c'est-à-dire que la vitesse est la même que celle des obus classiques et qu'il existe, de par sa conception, des problèmes de sécurité, notamment qu'il est sensible aux chocs provenant e.a. de l'ali-mentation des obus dans les canons, des chutes lors des transports et manipulations en général.

  
Le but de l'invention est de fournir un obus présentant, à

  
la fois, les avantages des susdits obus à sabot détachable

  
et multipurpose tout en en écartant les inconvénients.

  
L'obus selon l'invention présente, à cet effet, les avantages suivants:
- temps de vol court;
- effet perforant;
- effet incendiaire;
- effet explosif retardé;
- sécurité accrue.

  
Ledit but est atteint par la combinaison d'un projectile à effets multiples proprement dit et d'un élément entourant,

  
au moins partiellement, ce projectile, cet élément étant constitué par un sabot et une base.

  
Afin de mieux faire ressortir les caractéristiques et avantages de l'invention, deux exemples de mise en oeuvre sont décrits ci-après avec référence aux dessins annexés, dans lesquels:
la figure 1 représente en coupe longitudinale un obus selon l'invention; la figure 2 est une coupe selon la ligne II-II de la figure 1 ; la figure 3 représente une variante de la figure 1; la figure 4 est une coupe selon la ligne IV-IV de la f igure 3 .

  
L'obus tel que représenté dans les figures 1 et 2 est constitué par la combinaison d'un projectile 1 à effets multiples connu en soi et d'un élément formé par un sabot 2 en matière plastique entourant au moins partiellement ledit projectile et une base 3, également connue en soi.

  
En l'occurrence, le projectile 1, par exemple selon le brevet belge no 856.378, est emprisonné sur toute sa longueur dans ledit sabot, lequel est fixé sur une base 3, par exemple en aluminium.

  
Dans cette exécution, la partie avant du sabot 3 est creusée afin de former un logement 4 pour l'extrémité arrière du projectile. Une rondelle à dents est prévue entre ladite extrémité du projectile et le fond du sabot 2.

  
Il est à remarquer que le sabot 2 présente, à l'intérieur, sur toute sa longueur, des rainures 5, réalisant ainsi des lignes de déchirage 6 permettant, d'une manière connue, sous l'influence de forces radiales extérieures et au moment du départ de l'obus du canon, le dépeçage du sabot 2 et, ainsi, la séparation de la base 3 du projectile 1.

  
L'obus selon les figures 3 et 4 se différencie de celui des figures 1 et 2 par le fait que le projectile 1, par exemple selon le brevet belge no 740.309, est emprisonné dans un sabot 2 pourvu de rainures extérieures 7 de manière que les zones affaiblies ou lignes de déchirage

  
se situent à l'intérieur du sabot.

  
Il est évident qu'on obtient ainsi un obus englobant, à

  
la fois, tous les avantages des obus sous-calibrés et multipurpose tout en évitant les inconvénients de tels obus en soi.

  
L'invention n'est pas limitée aux exemples de réalisation susdécrits, de nombreuses modifications pouvant y être apportées, dans le cadre des revendications suivantes. 

  
Revendications.

  
1.- Obus à effets combinés, caractérisé en ce qu'il consiste substantiellement en la combinaison d'un projectile (1) à effets multiples, plus spécialement un projectile présentant, à la fois, un effet perforant, incendiaire et explosif et un élément entourant, au moins partiellement, ce projectile,

  
cet élément étant constitué par un sabot détachable (2) et une base (3).



  Combined effect shell Combined effect shell.

  
The invention relates to a combined effect shell.

  
APDS (Armor Piercing Discarding Sabot) shells are already known which consist substantially of

  
a sub-calibrated core in heavy metal and a sabot which detaches when the shell leaves the barrel.

  
One of the great advantages of such a shell is that the flight time for a given distance, compared to a conventional shell, is shorter due to the higher initial speed and the ratio of the mass of the nucleus per unit. cross-sectional area.

  
Another advantage of these shells is found in their high perforating effect, this as a result of the favorable ratio of the energy available per unit of transverse surface of the core.

  
However, the drawback of this shell is that the target effect is limited to a piercing or piercing / incendiary effect.

  
Multipurpose or PIE (Pyrotechnically Initiated Explosive) shells are also known, in particular shells with combined or multiple effects, of external shape similar to conventional shells, without the usual rocket. These projectiles are characterized in that the fragmentation effect is obtained by means of an explosive charge placed behind incendiary charges, this explosive charge being able to detonate without any fusing means and detonating only after a certain delay. An example of such a shell is described in Belgian patent no. 740.309. Another configuration of such a shell is described in Belgian patent no. 856.378.

  
A first advantage of this type of shell is its multiple effect; it presents in particular, at the same time, a perforating, incendiary and explosive effect (fragmentation).

  
Another advantage of this shell lies in the fact that the explosive and incendiary effects are delayed, which favorably influences the effectiveness of the shell especially in the case of shooting against lightly armored vehicles and against aircraft.

  
Yet another advantage is that the price of

  
this type of shell is relatively small due to the absence of a rocket.

  
The disadvantages of such a multipurpose shell are, in main order, that the shell is relatively slow, that is to say that the speed is the same as that of conventional shells and that it exists, by design , security problems, in particular that it is sensitive to shocks resulting from the feeding of shells into the barrels, falls during transport and handling in general.

  
The object of the invention is to provide a shell having, at

  
the advantages of the above detachable sabot shells

  
and multipurpose while avoiding the disadvantages.

  
The shell according to the invention has the following advantages for this purpose:
- short flight time;
- perforating effect;
- incendiary effect;
- delayed explosive effect;
- increased security.

  
Said aim is achieved by the combination of an actual multiple-effect projectile and a surrounding element,

  
at least partially, this projectile, this element consisting of a shoe and a base.

  
In order to better highlight the characteristics and advantages of the invention, two examples of implementation are described below with reference to the appended drawings, in which:
Figure 1 shows in longitudinal section a shell according to the invention; Figure 2 is a section along the line II-II of Figure 1; Figure 3 shows a variant of Figure 1; FIG. 4 is a section on the line IV-IV of FIG. 3.

  
The shell as shown in FIGS. 1 and 2 is formed by the combination of a multi-effect projectile 1 known per se and an element formed by a plastic shoe 2 at least partially surrounding said projectile and a base 3, also known per se.

  
In this case, the projectile 1, for example according to Belgian patent no. 856.378, is trapped over its entire length in said shoe, which is fixed on a base 3, for example made of aluminum.

  
In this embodiment, the front part of the shoe 3 is hollowed out in order to form a housing 4 for the rear end of the projectile. A toothed washer is provided between said end of the projectile and the bottom of shoe 2.

  
It should be noted that the shoe 2 has, inside, over its entire length, grooves 5, thus producing tear lines 6 allowing, in a known manner, under the influence of external radial forces and at the time from the start of the cannon shell, butchering of shoe 2 and, thus, separation of base 3 from projectile 1.

  
The shell according to FIGS. 3 and 4 differs from that of FIGS. 1 and 2 by the fact that the projectile 1, for example according to Belgian patent no. 740.309, is trapped in a shoe 2 provided with external grooves 7 so that the weakened areas or tear lines

  
are located inside the hoof.

  
It is obvious that one thus obtains an encompassing shell, with

  
at the same time, all the advantages of under-calibrated and multipurpose shells while avoiding the disadvantages of such shells in themselves.

  
The invention is not limited to the abovementioned exemplary embodiments, numerous modifications that can be made thereto, within the framework of the following claims.

  
Claims.
