EXPLOSIVE SENSITIVITY INFLUENCE ON ONE-AND TWO-LAYERED REACTIVE ARMORS BEHAVIOUR
The use of different ERA reactive cassettes is shown. Functioning rules of one-(ERAWA-1) and two-layered (ERAWA-2) reactive cassettes arepresented. The paper demonstrates different kinds of tests with ERAWa cassettes. There are some examples of the simulation of impact of differenttypes AP and HEAT ammunition on these cassettes. Simulation was based on free points computer codes. The propagation of the detonative wave in the explosive (PBX 9404 and RDX)has been described with the use of the approximation of so-called the detonative optics, in which the front ofthe detonative wave is a surface of the strong discontinuity, of the well-known shape (for the punctual initiationthe front is spherical), of the propagation speed, and the parameters of the medium on this surface are defined by the ChapmanJouguets point. Scattering of products of detonation and their influence on the liner of the RPG-7M projectile aredescribed with the use of equations of the hydrodynamics for the cylindrical symmetry. The results of simulation process of impact of AP ammunition of 7.62 mm, 12.7 mm 14.5 mm, and 125 mM caliber the type of APFSDS are illustrated in figures.
