Abstract:

The article considers the problem of the quality of service of different - priority network traffic in multiservice communication networks for military purposes. A feature of military communications networks is the differences in the significance of the transmitted information, that is, the need to categorize it, and the clearly expressed hierarchy of the control bodies between which it is transmitted. A technique has been proposed that makes it possible to evaluate the feasibility of using various queuing algorithms at different switching node load levels, taking into account the requirements for the quality of processing and the timeliness of delivery of transmitted heterogeneous and different - priority network traffic. The dependence of the quality of service of different - priority traffic on the degree of loading of the switching node under the conditions of using various queuing algorithms is studied.

Abstract:

The paper proposes an approach to managing a satellite communication system in conditions of bandwidth shortage. A similar situation is predicted during the hours of the greatest load with an increase in the number of subscribers of the satellite communication system. The solution to the presented problem situation is to improve the management methods of the satellite communication system in order to improve the quality of customer service. The proposed approach differs from the known ones in the implementation of satellite communication system control at two levels: physical and logical. At the same time, a comprehensive stability indicator is formulated and justified in the work, the evaluation of which forms the basis for the formation of the chosen method of controlling the communication system. The proposed method of controlling the satellite communication system in conditions of bandwidth shortage allows to achieve an improvement in the quality of customer service in terms of the probability of bringing information.

Abstract:

The article is devoted to the substantiation of the main parameters of informationredundant string converter. The basic requirements for primary string converter designed to operate under conditions of exposure to special loads on launch facilities are formulated. Recommendations are given on the selection of the string material, taking into account the temperature instability of the elastic modulus of the string material.

Abstract:

In the conditions of modern military conflicts, the problem of increasing the efficiency of the functioning of unmanned aerial vehicles (UAVs) due to their group use is being actualized. The solution of specific tasks through the use of UAVs causes the presence of restrictions on time indicators and timely fulfillment of tasks for their intended purpose in the conditions of a suddenly changing situation in the area of reconnaissance and strike operations. The use of network - centric principles of information interaction between the UAVs of the group and the introduction of non - relational databases into the system of their interaction will significantly expand the range of tasks solved using UAVs. The aim of the work is to solve the problem of distributing targets (scanning areas) between groups of UAVs connected by communication channels with ground control points in the conditions of information and technical impacts.

Abstract:

The development of special - purpose information systems contributed to their integration into the concept of network - centric warfare, which became the reason for their active use in the Armed Forces of the Russian Federation. In the concept of network - centric warfare, robotic complexes, from the point of view of information security, can be considered as remote information systems. In the conditions of improving the means of information and technical impact on information systems, threats to the security of information circulating in robotic complexes arise. The analysis of information and technical impacts on special - purpose robotic complexes has been carried out in order to identify their vulnerabilities, as well as the consequences of destructive effects associated with the use of electronic suppression equipment characterized by a violation of the integrity, accessibility and confidentiality of information.

Abstract:

The article is devoted to modeling the process of changing the states of reliability and information security indicators of mobile data centers - complex, managed information storage and processing systems with architectural flexibility and scalability. In the article, the author has attempted to formulate a new approach to modeling the process of functioning of mobile data centers, from the point of view of analyzing their technical reliability and security. The proposed model is based on classical controlled Markov chains in the form of difference stochastic equations and allows us to obtain the current values of reliability and information security indicators taking into account the dynamics of their discrete states change at discrete points in time. It is assumed that the proposed model will form the basis of the methodology of multi - criteria analysis of reliability and information security of mobile data centers developed by the author.

Abstract:

The article presents the results of a computational and theoretical study to establish the regularities of the influence of fuel temperature on the processes occurring in the fuel supply system of a tank power plant with a B-92C2 diesel engine. As a result of the conducted research, the regularities of the influence of fuel temperature on the indicators of processes in the fuel supply system of a diesel engine were revealed. It is revealed that when the fuel temperature decreases from 60 ℃ to 0 ℃, the maximum injection pressure into the combustion chamber can be increased from 100 MPa is up to 118 MPa, and the injection duration is reduced by 0,3 ms, which can favorably affect the quality of the workflow. To reduce the loads on the parts of the high - pressure fuel pump and its drive, an increase in the internal diameter of the high - pressure fuel lines is proposed.

Abstract:

The paper considers results of the experiments, where armored glasses have been irradiated with short wave ultraviolet radiation of a given power. The influence of ultraviolet radiation on the destruction of polymer compositions of armored glasses was noted. The irradiation has been carried out in several stages, after each of which the spectral transmission of the irradiated samples has been measured and the magnitude of the impacting energy flux has been estimated. The layout and characteristics of the installation for irradiating a prototype with ultraviolet radiation are described. The technique for measuring energy flux of laser radiation is described and the measurement results are presented in the paper. А dependence between changes in spectral transmission coefficient and duration of short - wave ultraviolet irradiation has been revealed. The selectivity of the effect of ultraviolet radiation on the transmission of armored glass for different wavelengths has been confirmed.

Abstract:

This article provides an overview of studies on the effects of an air shock wave on the human head. A description of the mechanism is presented and studies of the causes of traumatic brain injury resulting from exposure to air shock waves are considered. Studies on the influence of the presence of a helmet on a person’s head on the magnitude of the shock - wave load are considered. It is shown that the geometry of the helmet affects the nature of shock - wave flows and can contribute to the occurrence of additional shock surges. Based on the studies reviewed, it is concluded that the presence of a helmet not only does not protect a person’s head, since the protection of facial bones and cartilage is not provided, but can also lead to a change in the nature of traumatic brain injury, due to the peculiarities of shock - wave interaction with the helmet.

Abstract:

The paper is concerned with the development of the ballistic torso simulator in order to assess injury prevention when using body armor. Simple device of a mobile simulator is considered. The trunk is made in the form of a cylindrical tank filled with fluid, closed by an elastic membrane, with installed acceleration and intracavitary pressure sensors. The ballistic trunk simulator allows realizing a popular estimation method for injury prevention parameters when there is no any perforation to the armor caused by high speed projectiles, as well as blast wave effect or any secondary fragments impact. This improves an informative value of ballistic tests for the available and perspective armor.

Abstract:

The development of new composite bullet - resistant structures with a record low surface density based on diamond - containing silicon carbide ceramics «Ideal» has been carried out. A method has been developed for testing promising samples of armored structures using a metal frame that limits the free side surfaces of ceramic tiles. The advantage of this method lies in the use of a minimum amount of ceramics while maintaining the protective properties of the armor structure sample. The developed structures have a record low surface density. This value for samples conforming to the protection class Br5 is 30,2 kg/ m2, and for those conforming to the class Br6 - 63,48 kg/m2.

Abstract:

This article presents the results of numerical simulation of the interaction of a shock wave due to an electrohydraulic effect with a fixed thin metal plate. The joint solution of the equations of hydrodynamics, nonlinear acoustics, and mechanics made it possible to estimate the proportion of plastic deformation. A series of parametric studies made it possible to calculate the residual deformation amplitude depending on the distance between the explosion source and the thin plate. Which can act as a simple pressure sensor. The absence of resonant effects due to the damping effect of the environment, which are theoretically possible when the forced oscillation frequency of the plate coincides with one of the natural ones, identified in the preliminary modal analysis, is demonstrated.
