Munition Comprising a Body, an Explosive Charge and Wedging Means Between the Body and the Explosive Charge

Abstract

A munition, such as a missile, a rocket or a projectile, includes a body forming an internal volume and an explosive charge confined in the internal volume. It applies notably, but not exclusively, to munitions of which the explosive charge comprises coated explosive molecules in a polymer binder. The explosive charge substantially conforms to the shape of an internal longitudinal surface of the internal volume, the internal surface being substantially of revolution about an axis and including protruding portions and/or cavities making it possible to keep the explosive charge wedged in the body.

1 . A munition comprising:
 a body forming an internal volume, and   an explosive charge confined in the internal volume, the explosive charge substantially conforming to the shape of an internal longitudinal surface of the internal volume,   the longitudinal surface being substantially of revolution about an axis and comprising protruding portions and/or cavities making it possible to keep the explosive charge wedged in the body.   
     
     
         2 . The munition of  claim 1 , wherein at least one protruding portion or one cavity forms a contact surface capable of preventing the explosive charge from rotating on the axis relative to the body. 
     
     
         3 . The munition of  claim 1 , wherein protruding portions and/or cavities are distributed symmetrically along the axis. 
     
     
         4 . The munition of  claim 1 , wherein at least one protruding portion or one cavity is circular on the axis. 
     
     
         5 . The munition of  claim 1 , wherein at least two protruding portions and/or cavities are not at the same level on the axis. 
     
     
         6 . The munition of  claim 1 , wherein a height of the protruding portions and/or a depth of the cavities are a function of a difference between an expansion coefficient of the body and an expansion coefficient of the explosive charge. 
     
     
         7 . The munition of  claim 1 , wherein the protruding portions are bosses. 
     
     
         8 . The munition of  claim 1 , further comprising a cup closing one end of the internal volume, the explosive charge being bonded to at least one portion of an internal surface of the cup. 
     
     
         9 . The munition of  claim 1 , wherein the explosive charge comprises coated explosive molecules in a polymerized binder.
