Armaments are characterized by groups of technical and operational characteristics, each of which is divided into separate indicators. These include effectiveness, ranges of use; combat capability, reliability, operational safety. Under the effectiveness of the missile’s warhead it shall be understood the amount of damage that can cause an explosion in combat environment.
The aim of the work is to evaluate the effectiveness of the blast-fragmentation warhead by modeling and analyzing the damaging of injurious effects.
Primary blast-fragmentation warhead effects are a shock wave, which is characterized by a specific air pressure on its front and a specific impulse, as well as fragments that move at high speed.
Determining the effectiveness of target neutralization by the fragmentation effect of the warhead is described by a set of positions of the j units, each of which is characterized by the fractional volume, the angle of inclination, the type of losses.
Due to the independent impact on the target of several effects, their whole impact can be estimated by the total probability of individual injurious effects.
The effectiveness of warhead is assessed by the probability of hitting the target. It is most rational to achieve the goal by reducing the distance to the explosion while increasing accuracy. This is a global development trend.
Other ways are either to increase its explosive power or structurally - the number of fragments.
It is necessary to indicate experimental data on the number of holes per unit area for a given distance and characteristics of the warhead of the missile.
Assessing the probability of the debris impact requires clarification of the characteristics of the warhead, the characteristics of the vulnerable spots of the target and the angle of the missile approach.
It is advisable to make the trajectory of the missile approach guided, taking into account the modularity of the configuration. This reduces ammunition consumption and increases the efficiency of the warhead.
