En calculant convenablement la. grosseur de grains.du fer fritte, ainsi que la pression de compression requise pour la production de celui. ci, on peut réaliser des bagues ou corps de garniture capables de résister à l'impact du projectile et à la formation primai-

De plus, l'ensemble du revêtement intérieur de la charge creuse peut être réalisé en fer fritte, dans lequel cas on peut renoncer aux bagues des garniture, spéciales, tout
<EMI ID=13.1>
moulage sous pression du fer fritte, en vue de produire de tels revêtements ou chemises de faible épaisseur, est quelque peu compliqué du point de vue de la fabrication, il convient de donner la préférence aux bagues,de garniture.
Donc, grSce à l'emploi du fer fritté, qui se décompose aisément en ses particules primitives, on a la possibilité" d'atteindre avec certitude l'effet incendiaire recherché, sans <EMI ID=14.1>

The shaped charge explosive devices have explosive charges by 1 in the appendix drawing-
<EMI ID = 1.1>
or other material, gets a more intense effect.
<EMI ID = 2.1> <EMI ID = 3.1>
a shaped charge is not sufficient if it is not accompanied by destruction inside the affected Vault.
However, the effect of a shaped charge is precisely '
<EMI ID = 4.1>
very narrow. This in turn determines a small spray angle inside the affected shelter. It therefore seems necessary
<EMI ID = 5.1>
so that it is exerted on the totality of the targeted space.
To this end, gold has already recommended providing the
<EMI ID = 6.1>
However, the effect of this system is insufficient for the following reasons; so as not to hinder the development
<EMI ID = 7.1>
of the cockpit or bombardment room if the special lining is made of a relatively porous sintered iron. By properly calculating the. grain size of the sintered iron, as well as the compression pressure required for the production of it. Here, it is possible to produce rings or packing bodies capable of withstanding the impact of the projectile and the primary formation.
<EMI ID = 8.1>
only after passing through the ejection channel and undergoing the ensuing disintegration.
This disintegration which occurs at maximum temperatures. inside the passenger compartment filled with air, results in the ignition and combustion of the projected particles.

vention of another nature.
In addition, the entire interior lining of the shaped charge can be made of sintered iron, in which case the special packing rings can be dispensed with.
<EMI ID = 13.1>
Die casting of sintered iron, in order to produce such thin coatings or liners, is somewhat complicated from the point of view of manufacture, the rings, packing should be preferred.
So, thanks to the use of sintered iron, which easily decomposes into its primitive particles, we have the possibility "to achieve with certainty the desired incendiary effect, without <EMI ID = 14.1>
