Abstract

The present invention relates to a system for launching a charge or projectile ( 40 ), characterized in that it comprises: a means ( 10, 12 ) of launching a charge ( 40 ), at least one line ( 20 ) fixed by a first end ( 21 ) to a body ( 10 ) connected to the launch means and by a second end ( 22 ) to the charge ( 40 ), and a slowing device ( 30 ) associated in a controlled manner with the line ( 20 ).

1 . System for launching a charge or projectile ( 40 ), characterized in that it comprises: 
 a means ( 10 ,  12 ) of launching a charge ( 40 ),    at least one line ( 20 ), wound into a coil, fixed by a first end ( 21 ) to a body ( 10 ) connected to the launch means and by a second end ( 22 ) to the charge ( 40 ), and    a slowing device ( 30 ) associated in a controlled manner with the line ( 20 ) so as to carry out controlled slowing of the charge or projectile ( 40 ).    
     
     
         2 . System according to  claim 1 , characterized in that the slowing device ( 30 ) is associated with a limited portion of the line ( 20 ).  
     
     
         3 . System according to one of claims  1  and  2 , characterized in that the slowing device ( 30 ) is associated with a region of the line ( 20 ) that is some way between its two ends ( 21 ,  22 ).  
     
     
         4 . System according to  claim 3 , characterized in that the two portions of line ( 23 ,  24 ) located on each side of the slowing device ( 30 ) are each respectively coiled ( 25 ,  26 ).  
     
     
         5 . System according to one of  claims 1  to  4 , characterized in that the slowing device ( 30 ) is of the friction type.  
     
     
         6 . System according to  claim 5 , characterized in that the slowing device ( 30 ) is made up of a rigid structure ( 32 ) equipped with a series of through-perforations perforations ( 34 ) through which the line ( 20 ) is engaged, for example in a spiral, in a loop, in a sinusoid, or alternatively in any other appropriate configuration.  
     
     
         7 . System according to one of claims  5  and  6 , characterized in that the slowing device ( 30 ) comprises a rigid annular roundel ( 32 ) which has through-orifices ( 34 ), through at least some of which an intermediate region of the line ( 20 ) is wound, for example in a spiral, in a loop, in a sinusoid or alternatively in any other appropriate configuration.  
     
     
         8 . System according to  claim 7 , characterized in that the roundel ( 32 ) has no sharp edges in the running path of the line ( 20 ).  
     
     
         9 . System according to  claim 8 , characterized in that the passages ( 34 ) formed in the roundel ( 32 ) widen at their respective entries and exits on the faces of the roundel ( 32 ) so that they meet these faces approximately tangentially and avoid damaging the line ( 20 ) as it runs, and likewise the internal periphery ( 33 ) of the roundel ( 32 ), over which the line ( 20 ) runs is rounded, for example in the form of a torus-shaped cap.  
     
     
         10 . System according to one of  claims 1  to  9 , characterized in that it comprises several lines ( 20 ) associated with a common charge ( 40 ).  
     
     
         11 . System according to one of  claims 1  to  10 , characterized in that it comprises several slowing devices ( 30 ) inserted selectively along the length of the line ( 20 ) so as to control the slowing-down dynamics.  
     
     
         12 . System according to one of  claims 1  to  11 , characterized in that the launch means comprises a body ( 10 ) forming a mortar and a pyrotechnic chain ( 12 ) capable, when implemented, of launching or propelling a charge or projectile ( 40 ).
