Numerical analysis of the inhomogeneous obstacle influence on the precursor shaped charge warhead performance
Апстракт
Purpose of the precursor shaped charge warhead is to initiate the Explosive Reactive Armor (ERA) and thus
provide an unobstructed path to the jet of the main shaped charge. The precursor warhead is most commonly placed in
the front of the missile where it is surrounded by other subsystems. All of the subsystems which lay on the path of the
precursor warhead’s shaped charge jet represent the obstacle that will decrease its efficiency. The goal of this paper is
to analyze the precursor warhead’s performance in a case where the inhomogeneous obstacle is placed in front of it.
The numerical analysis of the obstructed formation process was performed in order to determine the properties of the
formed jet using ANSYS AUTODYN 2D software. For the existing missile configuration, jet formation process and
precursor warhead's performance against ERA were analyzed numerically. Significant differences in formed jet's
properties were observed for the simulations with and without the inhomoge...neous obstacles. In the case of
inhomogeneous obstacle it is present decreasing of jet tip velocity for around 23%, decreasing of jet tip dimaeter for
around 50% and jet time are delayed in contact with ERA front panel for around 10 µs. Obtained results indicate that
in the observed cases, formed jet has enough energy to initiate the explosive reactive armor.
