Description: In an article, the method for evaluating the reference coverage area value of cassette high-explosive submunition of the multiple launch rocket system is considered. The analysis of existing methods for calculating the reference damage area was carried out, which showed that these calculations do not take into account the incidence angle of cluster munitions to the surface at the target. The necessity of additional consideration the incidence angle to the surface of the high-explosive cluster submunition shell splinters, as well as the height of the vulnerable part of the elementary destruction object relative to the flow of damaging elements when assessing the value of the reference lesion area was confirmed. The methodology of the study is using the methods of numerical integration of a differential equations system describing the movement of the combat element mass center in a vertical plane to obtain the dependence of the area value of grouping the impact incidence points of combat elements from the firing range. The trajectories of the striking elements were described analytically in the range of scattering angles of shell splinters to estimate their possible ranges, spatial geometry for deriving the functional dependence the values of the upper and lower bounds of the striking elements flow relative to the incidence angle values of combat elements to the surface, the spread of the angles and the direction of fragment distribution. The simplest model of the vulnerability of a given elementary object was also used to estimate the reference area of fragmentation damage. The dependence of the reference kills area dimensions of cluster submunition shell splinters which formed when exploding one cassette of a high-explosive cluster submunition on the firing range was obtained. Achieved results can be used at calculating the required number of rocket projectiles for inflicting specified damage to a group object.
