  "Projectile explosible à charge éclairante, comportant un conducteur métallique pour le logement de la charge détonante dans la charge éclairante" 

  
On connaît, des projectiles explosibles à trace lumineuse, dont l'allumage s'opère par la charge éclairante qui se consume.

  
Dans ce cas, il est d'usage de transmettre la chaleur de la charge éclairante par l'intermédiaire d'un conducteur métallique, à la charge détonante. La mise en place de la charge détonante donne

il a déjà été proposé d'introduire la charge détonante ou la charge percutante prévue au lieu de la charge détonante, dans une cavité en forme de cloche prévue dans une douille formée sans bavures, qui contient la charge éclairante, la douille étant alors placée par l'arrière, dans le projectile. La fabrication d'un tel projectile' est coûteuse.

  
La fabrication du projectile et de l'amorce d'éclatement est, i selon l'invention, simplifiée grâce au fait que le conducteur métal-

  "Explosive projectile with an illuminating charge, comprising a metallic conductor for accommodating the detonating charge in the illuminating charge"

  
We know explosive projectiles with luminous traces, the ignition of which takes place by the illuminating charge which is consumed.

  
In this case, it is customary to transmit the heat of the illuminating charge via a metallic conductor, to the detonating charge. The placement of the detonating charge gives

  
 <EMI ID = 1.1>

  
it has already been proposed to introduce the detonating charge or the percussion charge provided instead of the detonating charge, into a bell-shaped cavity provided in a socket formed without burrs, which contains the illuminating charge, the socket then being placed by the rear, in the projectile. The manufacture of such a projectile is expensive.

  
The manufacture of the projectile and of the bursting primer is, according to the invention, simplified thanks to the fact that the metal conductor

  
 <EMI ID = 2.1>

  
either pressed into an inner annular groove of the projectile case, or pressed firmly against the inner wall of the projectile case.

  
Examples of embodiments of the invention are described below with reference to the accompanying drawing.

  
In Figs. 1 to 3, the projectile 1 is provided with a bottom
