CA 2592760

The invention relates to a reactive protective device that does not cause end- ballistically relevant splintering for an object to be protected, characterized in that two pyrotechnic layers (2, 3) slanted in the active area of the threat are placed on both sides of a rigid or flexible, single layer or multilayer support (4) of any shape so that shock waves and reaction gases are formed once both layers are ignited and these shock waves and reaction gases are accelerated at a very high speed at an angle both against as well as in the direction of the penetrating threat in such a manner that the pyrotechnic protective surface is in a dynamic balance for almost the entire active time.

L'invention concerne un dispositif de protection réactif n'induisant pas de fragmentation significative en termes de balistique terminale au niveau de l'objet à protéger. Ledit dispositif de protection réactif se caractérise en que, dans la zone active du danger, deux couches (2, 3) pyrotechniques inclinées sont disposées de part et d'autre d'un support (5) rigide ou flexible, mono- ou multicouche de n'importe quelle configuration, de sorte à former des ondes de choc et des gaz réactifs, après mise à feu des deux couches, et que lesdites ondes de choc et lesdits gaz réactifs soient accélérés à très grande vitesse, aussi bien à l'encontre, qu'en direction du danger marqué, afin que la surface de protection pyrotechnique se trouve en équilibre dynamique pendant pratiquement tout le temps d'action.
