Description: In the article methodology of analytical determination of the required minimum expense of large caliber rockets with the cassette warhead equipped by blast fragmentation battle elements is considered. The subject of research is a required minimum expense of rockets calculation process. A research object is a process of analytical estimation the adduced area of defeat. This adduced area of defeat is formed at the explosion of a few blast fragmentation battle elements that get on position of group object at firing on the define distance. Methodology consists of methods: points of battle elements falling grouping centers dispersion indexes estimation; complete starting data preparation errors estimation; battle elements falling grouping centers area estimation; models of elementary object vulnerability; value of the adduced area over of fragment defeat estimation; middle amount of battle elements that get on group object position estimation. Basic hypotheses stay in basis of analytical calculations: smooth dispersion of elementary objects on the position and battle elements across area of their dispersion. The error values of the complete preparation of data for launching rockets for the reference values of firing ranges were estimated. For two groups of errors of the dispersion components, the values of the dispersion indicators of the centers of grouping of the points of incidence of combat elements relative to the aiming point for the reference values of the firing ranges are estimated. On the basis of the considered methodology the calculation of the required minimum expense of large caliber rockets with cassette battle parts equipped by blast fragmentation battle elements, for suppression (eliminations) of calculated group object for the basic values of firing range is conducted. Polynomial interpolation of the obtained data for the estimation of the required minimum rockets expense for firing on any distance is performed. The estimation of complete data preparation errors influence degree on the required expense of rockets is carried out. Corresponding tables and charts are given.


Keywords: rocket, cassette battle part, blast fragmentation battle elements, required expense of rockets, adduced square of fragment defeat area
