Abstract:

The article presents a prognostic method for estimating the severity of a person’s lesions by an air shock wave based on the duration of its positive phase and overpressure, which allows to calculate the probability of lesions of each of the five classes of human lesion severity (baroinjury, mild lesions, moderate lesions, severe and fatal lesions, fatal injuries). Comparison of the results of calculations with experimental results extrapolated from animals to humans (112 calculations) showed that the proportion of errors made in determining the probability of occurrence of primary injuries caused by exposure to an air shock wave was 0,19, all errors were errors of the first kind. The developed method is recommended for application for solving applied problems of ensuring the safety of blasting operations and measures to counteract terrorism in the context of a shortage of time.

Abstract:

The paper shows the mathematical description of kerosene ignition, combustion and fire decay processes located over confined space floor. The heat exchange process among the structures located in the confined space and the chemical reactions describing the combustion process are considered. The suggested mathematical model (programmed by code) is a 0-dimensional and does not consider fire front propagation. The obtained results show the relationships between thermo-dynamic and gas-dynamic parameters versus time, which are the initial conditions for subsequent reliability and strength calculations.

Abstract:

A task of a semi-spheric and flat impact of a solid object against incompressible liquid followed by inertial movement and temporary cavity formation is investigated. We received the analytic statements describing: a change of traveling speed of environments’ boundaries; the maximum movement of a semi-spheric and flat object inside incompressible liquid; the law of enlargement of the cavern and inertial liquid movement, which describes temporary cavity formation. From a practical point of view, the possibility of calculating the parameters of the temporary cavity (cavern) such as maximum depth, projection area, volume, etc. allows you to evaluate the influence of various factors on the predicted severity of post-injury contusion injury (PCI) when the body armor does not penetrate with a striking element of ammunition.

The paper provides a brief overview of the existing thin-layer thermal insulation coatings. Presents modern methods of camouflage painting of buildings and structures, as well as ground infrastructure insulating coatings. A new composition of thin-layer heat-insulating coating is proposed, which can be recommended for hiding military ground infrastructure objects (buildings, structures and external life support systems) from detection by infrared reconnaissance equipment. From the point of increase of heat-shielding properties, the introduction into it of solid phases of non-autoclaved foam concrete of average density D150, which have high values of standard entropy of formation, is scientifically justified. The calculation of the coefficient of thermal conductivity of the resulting composition was made according to the classical Van Vleck formula. The results of X-ray studies of samples of foam concrete.

Abstract:

The classification of ballistic fiber-reinforced ceramic-matrix composites (KMC) is distinguished, and the review and analysis of the current state and trends in the development of ways to improve ballistic characteristics based on the formation of a CMC with a homogeneous fibrous or hybrid (dispersed and fibrous filler) structure, creating materials with varying properties in the bulk (layered and gradient). It is shown that the greatest ballistic effect can be obtained in the direction of creating functionally graded and layered CMCS. The analysis of methods for producing CMC shows that solid-phase methods and methods based on liquid-phase processes of infiltration of melts of reaction metals are the most preferable in terms of economic and ballistic efficiency.

In this article, we consider the results of experimental studies describing the influence of the vibrational effect of an aircraft on the concentration of anti-liquid crystal liquid in jet fuel. The order of carrying out the full factorial experiment, the multidimensional regression model, as well as information sources for constructing the multidimensional regression model, the mathematical model are described. A preliminary experiment is considered in which the temperature of the beginning of the crystallization of the tested fuels is determined, and the limitations (lower and upper limits) of the factors and the hypothesis about the presumed form of the regression equation are then revealed. Based on the study, the author proves the relationship between three factors: the frequency of vibration, the temperature of the mixture of fuel for jet engines and anti-wax liquid, the temperature of the beginning of the crystallization of fuel for jet engines.

The paper considers the features of information exchange between autonomous underwater vehicles during their operation in a group. Using the example of using a group of devices for conducting seismic surveys, the most acute problems are considered, the solution of which is impossible without information exchange: navigation, coordination and reconfiguration of the group. Various situations are analyzed that require mutual information exchange between the devices. Algorithms for navigation, coordination and reconfiguration using information exchange between devices are proposed. The effect of time delays caused by the exchange of information on the efficiency of conducting seismic prospecting is assessed. The received estimations allow to generate algorithms of behavior of devices at the decision of tasks of navigation, coordination and reconfiguration of group, and also to approach consciously to a choice of modems for realization of information exchange between devices in a group.

Abstract:

In modern conditions, the development of the military organization of the state is inextricably linked with the improvement of the system of material security for servicemen, which entails a multiple increase in the range of supplies to the troops and their value. These issues are typical for the Armed Forces of the Russian Federation, the troops of the national guard of Russia and other special consumers. In this regard, the most important direction of the development of the material support system over the past years is the increase in the efficiency of the use of allocated resources, the rational use of material assets and the avoidance of losses, losses and shortages. One of the solutions to these tasks may be the introduction of control identification marks based on radio frequency labels and the formation of a system of operational automated accounting.

Abstract:

The article presents the results of an anonymous questionnaire of 83 servicemen aged 19 to 45 years who are on military service under a contract. The questionnaire contained groups of questions reflecting the acoustic load, the level of professional knowledge related to the use of personal protective equipment (PPE) of the hearing organ, the presence in the history of cases of acute acoustic trauma, treatment in medical institutions, etc. All interviewed stated that they had no PPE hearing organ. The presence of an acute acoustic trauma in the anamnesis was noted by 6 people. 76,2% of servicemen after shooting without PPE, there were signs of adverse impact of impulse noise on the body: ringing, stuffing, tinnitus lasting up to one day. To prevent the adverse effects of impulse noise, it is proposed to provide servicemen with effective hearing protection equipment, to raise the level of professional knowledge of servicemen, to convince them of the mandatory application of PPE during shooting, and to introduce responsibility for refusing to use them.
