Abstract:

Modern geopolitical challenges require the creation of a system of aboard military bases (AMB) to protect and promote Russia's national interests. At the same time, the AMB itself is a limited «resource» that requires optimal distribution, so the synthesis of a system of aboard military bases is the improvement task in a complex systems theory. The proposed concept for the synthesis of the AMB system is based on the General principles of the system approach, but at the same time includes a number of features that are characterized by the synthesized system. The solution of the synthesis problem is reduced to the need to determine both the location of aboard military facilities and their type. The solution to the problem of choosing the locations of the AMB it is possible on the basis of the identification of cores of the centers of power, and the analysis of the detected «cores» will help to determine the type of AMB, it is required to find the optimal distribution of resource in the form of the AMB equally the obje

Abstract:

The article is devoted to the development of a method for guaranteed estimation of the reliability of mechanical parts of technical systems structures at the early stages of development. The main difference of the developed algorithm from the results of previous studies is that it reflects a new approach to reliability estimation based on the use of extreme distributions of extreme random variables. This allows to claim a method for a guaranteed reliability estimation of mechanical parts of structures on the basis of a comparative estimation of the probability of failure - free operation using a variety of information situations.

Abstract:

An algorithm for estimating the spatial coordinates and current time of the consumer in conditions of limited visibility of spacecraft of global navigation systems in the absence of a priori information about the discrepancy between the receiver time scale and the system scale is proposed. To solve the navigation problem, optimization algorithms based on the use of empirical search methods are proposed. The calculation of the accuracy of estimating the position vector of the consumer in visibility conditions from one to three navigation spacecraft with an unknown mixing of the receiver time scale relative to the system one is made. The algorithm for estimating the spatial coordinates and the current time of the consumer is recommended to be used as a backup, forming a reserve of stability in case of poor observability of the vector of the estimated parameters, which is currently relevant.

Abstract:

A model of the space object recognition system is proposed, which, unlike the existing ones, makes it possible to form the reflection spectra of space objects and, taking them into account, to determine the type of space objects. The formation of reflection spectra is performed according to a linear law based on the mixing of laboratory reflection spectra of materials and coatings, which makes it possible to reproduce the spectral distribution of the optical radiation flux reflected from an artificial earth satellite in the visible range. The article substantiates the impossibility of currently existing ground - based observation facilities to provide the resolution required for separate observation of individual structural elements of an artificial earth satellite, which determines the need to study and analyze spectrophotometric information, namely reflection spectra. The model is based on the assumption that if the surface of an artificial earth satellite reflecting at the time of observation is divided proportionally in accordance with the content of the materials and coatings of which it consists, then the reflected radiation transmits the spectral characteristics of these materials in the same proportions.

Abstract:

The results of physical and mathematical modeling of the development of thermal gravitational convection of smoke inside boxes of different sizes are compared. Physical modeling was performed inside the boxes in the form of a rectangular parallelepiped with a volume of 29,7 m3, as well as 0,55 and 0,16 m3. The experiments evaluated the temperature and mass concentration of smoke. Numerical calculations were performed on threedimensional finite - difference grids. The averaged three - dimensional convection motion of air was described by Reynolds equations in the variables speed - pressure - temperature. The turbulent characteristics of the air were determined using a two - parameter k - ε turbulence model. The results of the comparison show the reliability of the original differential equations of air motion, boundary and initial conditions, and their finitedifference approximation. It is shown that it is necessary to use equations that assume its inertial but passive behavior when describing the movement of smoke. The results will be useful in developing ways to use smoke grenades in protected areas.

Abstract:

The article presents the results of a study of the dependence of the radiation pattern parameters of phased antenna arrays on their size and construction method. The analysis of the studied dependencies shows that due to a more rational placement of antenna elements, the number of the latter, and, consequently, the overall weight characteristics and power consumption can be significantly reduced without changing the specified energy parameters of the antenna. The paper also considers the possibility of redistributing the energy of the side lobes by using a lattice geometry other than the square one. This characteristic allows you to take into account the features of the radio - electronic environment to reduce the level of interference (or unwanted radiation).

Abstract:

Currently, management of complex organizational and technical objects is difficult to imagine without an automated management system based on an information subsystem. In turn, to organize effective work with the information subsystem, it is necessary to create an information management network. This article offers a methodological approach to the mathematical description of the functioning of an information management network with distributed heterogeneous information and computing resources in the interests of a special - purpose support and decision - making system. The necessity of creating an information management network to provide the required values of the stability indicator for the functioning of the information subsystem of the Unified information space for special purposes is justified.

The results of physical and mathematical modeling of the development of thermal gravitational convection of smoke inside the protected area are compared. Physical modeling was performed inside a rectangular compartment with a volume of 31,7 m3.The experiments evaluated the mass concentration of smoke and the range of visibility in it. Mathematical modeling was performed in a three - dimensional setting. The averaged motion of air was described by Reynolds equations in the variables speed - pressure - temperature. The turbulent characteristics of the air were determined using a two - parameter k - ε turbulence model. The movement of smoke was described by equations that assume its inertial, but passive (due to the low volume concentration) behavior. The results of the comparison show the reliability of the original differential equations of smoke motion, boundary and initial conditions, and their finite - difference approximation. The results will be useful in developing ways to use smoke grenades in protected areas.

Abstract:

The article discusses the model and algorithm for substantiating the composition of equipment and specialists for conducting field tests of artillery weapons systems. The model is based on the representation of the procedure for forming equipment and specialists in the form of a discrete mathematical programming problem. Within the framework of the model, a variant of representing labor costs in the form of fuzzy variables set by intervals of possible values is considered. To solve the problem of discrete programming related to the NP complexity class, an iterative algorithm for sequentially forming a plan for attracting equipment and specialists for testing is proposed. The proposed model and algorithm are the basis for creating specific methods for forming the optimal composition of equipment and specialists when planning appropriate tests.

Abstract:

The article considers a passive range - finding method for estimating the location of a moving correction projectile at discrete time points. The analysis of existing developments aimed at improving the effectiveness of the use of artillery systems when firing ammunition in conventional equipment and the accuracy of artillery fire. An approach is proposed to improve the efficiency of artillery firing by implementing the developed method, which provides the construction of the projectile flight path from the initial to the probable point of fall. The method is based on the hypothesis that the use of a correction projectile on the intended target is fixed on the trajectory at certain discrete times. A sequential solution to the problem of determining the position of the correction projectile on the trajectory is presented.

Abstract:

The issue of assessing the thermal state of the barrels of small - caliber automatic weapons during firing is considered. To this end, the article investigates the effect of heating the barrels of automatic weapons on the initial velocity of the projectile. Based on this, an algorithm is proposed for assessing the thermal state of the barrels of small - caliber automatic weapons based on the determination of thermal processes occurring in the barrel bore during firing. The proposed algorithm for assessing the thermal state of barrels makes it possible to analyze their performance based on determining the change in the temperature field of the barrel unit heated during firing, taking into account the firing mode.

Abstract:

The paper proposes the use of the Yakheev relative comparison criterion to assess the impact hazard of the stowage massif in comparison with the rock and ore massif. In the results of calculations of this criterion using physical and mechanical properties, it is established that the impact hazard of the rock is 14,91, and the ore is 13,05 relative units compared to the 1st relative unit of the stowing array. From this, it was concluded that the stowing array is not a shock hazard, which was confirmed by the statistics of mining bumps at the Oktyabrsky mine. Based on the article, the following conclusions are made: for predicting the impact hazard, we can recommend the relative multidimensional of comparison criterion of Yakheev, and as a way to combat mountain impacts, we can place workings in the stowing array.
