The article describes the results of simulation of the interaction of the striking element with a flexible link structure in the form of chain mail. A three-dimensional model of interacting bodies with high simulation accuracy for a bullet (a three-layer shell with a 5.45 mm core) was developed. As a result of modeling the step experiment is carried out and the most vulnerable points of the link structure are determined, which determine the probabilistic nature of formation of processes of deviation and crushing of the drummer. The presented model proves the possibility of a positive effect on the resistance to the effects of kinetic damaging elements of structures with irregular surface and volume, having the properties of shaping. The probabilistic outcome of the resistance relative to the coordinates of the surface, suggests the need to develop new methods for assessing resistance, based on the fractal geometry of self-similar systems.

Abstract:

Changes in the nature of military dangers and threats to the Russian Federation that have arisen in recent years impose new requirements on the content and order of the activities of military command and control bodies in solving problems in the field of defense and state security. The experience of carrying out operational training activities has shown that the amount of information that must be taken into account by the governing persons of these bodies in order to form rational decisions is steadily growing, and the applied models, methods and technologies do not ensure its full and sufficiently adequate accounting. The article presents the algorithm of the work of the military command and control bodies, taking into account the use of information-analytical support tools, and also describes the requirements for these tools and the features of their construction. In general, the results of the research are a contribution to the management theory in terms of creating tools for providing information and analytical support for the activities of military command and control bodies.

Abstract:

Explosives are a particularly important energy component of many economies and manufacturability of systems for the initiation of explosives affects the defense of the state as well as safety in handling and storage of ammunition. Some of primary explosives used today are extremely unsafe and vulnerable to external influences, what leads to increased injury risk at the enterprises, involved in their manufacture, which bounded with a high probability of unauthorized explosion. The solution to this important problem may be a different approach to the method of explosives initiation based on the exclusion of primary explosives from projectile design, replacing it with safer laser initiation system for explosives. This decision was taken into account for a long time, however until relatively recently time dimensions, power, weight and price of laser machine were unacceptable for effective explosives initiation.

In the present article the basic algorithm of decoding DTMF-signal in receivers of improvised radio-controlled explosive devices is considered. To do this, first of all, it is necessary to allocate the energy of eight frequency components in the received signal: four for the lower part and four for the upper part of the spectral region of the main harmonics. The article deals with the calculation of the energy spectrum of signals using fast Fourier transform (FFT). It also shows the calculation of the spectrum, using filters Hertzel, tuned to these frequencies. The resulting expressions for their definition are derived. Their comparison is carried out and advantage of the decoder on the basis of the Gertzel filter is established.

Hit probabilities to different areas of a shooting target «breast silhouette with circles» using dispersion parameters corresponding semi-automatic Makarov pistol on the basis of formulas for Rayleigh and Rice distribution and the two-dimensional Laplace- Gaussian distributions have been estimated. The hit probability calculation method is based on the numerical integration of the double integral, in which the integrand is the probability density function, and the limit corresponds to a closed contour of the target. A mathematical interpretation of the «hit probability» is the volume of a figure that is bounded from above by the two-dimensional Laplace-Gaussian distribution, and from below by a geometric plane with a contour corresponding to the silhouette of the shooting target.

The article describes the summary results of experimental studies of the characteristics of resistance to the impact of a porous cast aluminum (PСA) striker strengthened by microarc oxidation. In the preliminary experiment, the method of microarc oxidation PСA was confirmed and the resistance to the impact of the drummer relative to non-oxidized samples was determined. The positive effect of the growth of ballistic resistance of the hardened PСA is confirmed, as well as the fundamental design factors determining its dissipative properties are determined. The depth of penetration of a heavy impactor into porous aluminum strengthened by microarc oxidation is determined. The approbation of one of the methods of PСA oxidation confirmed the necessity of electrolyte cooling and technological production of the current line in the body of the oxidized sample.

The paper discusses the design and effect on target of non-lethal ammunition made by «active shell» scheme. Paper shows the influence of load coefficient (the ratio of the composition mass to the shell mass) on ammunition acoustic and light action. The light effect is characterized by the dependence of energy illumination on time. At low load coefficients the combustion of «active shell», which is dispersed by the explosion, is out of compression phase of weak shock wave and last one does not receive extra energy. The intensity of the wave generated by such explosion is significantly reduced compared to the explosion of explosive charge without an «active shell». In addition, at a lower maximum value of irradiation, the integral characteristic of radiation will be higher, which allows to achieve a longer time of «temporary blinding» of the target with a lower probability of irreversible damage to the eye.

Abstract:

To date, in the military and civil satellite radio communications systems, wide-band phaseshifted signals are widely used (DSSS - Direct sequence spread spectrum). The principle of their formation consists in multiplying the carrier signal by a pseudo-random sequence (PNP) with a clock frequency much exceeding the bandwidth of the information signal. The effect of multiple spreading of the spectrum makes it possible to achieve the required reliability of information transmission, even at small signal-to-noise ratios, which makes it possible to use the RSSMS to transmit information critical to the user (for example, control commands and overheads) in a complicated interference situation. In this article, the issues of noise immunity of FMBSs under the influence of stationary interference, including obstructive, band-centered and narrow-band interference.
