ABSTRACT:
A warhead having hollow charge, such as a bomblet as well as a large caliber armor-piercing projectile has an improved detonation wave guide arrangement which preferably produces a high pyrophoric effect at target impact.
The detonation wave guide itself is made of an incendiary-active (flamable) material, whereby a strong exothermal reaction is released by shock waves at target impact in the binding substances which form the wave guide. By exclusively initiating this exothermal reaction and incendiary effect by means of shock waves a rapid and simple introduction of the reaction in a few microseconds is achieved. The binding substance consists of metal particles and gases embedded in matrix. These metal particles have a high combustion enthalpy and the matrix is made of an organic polymer. The shock waves cause a decomposition of the metal particles of the matrix and a simultaneous temperature increase and a chemical reaction is triggered, whereby by means of the reaction products the temperature is further increased and by virtue of the release of large heat energy even poorly flamable substances are burned.
